When Did Mount Saint Helens Last Erupt

1980 Cataclysmic Eruption

At least in part, the Catholic Church recognized the importance of the Protestant Reformation when it erupted in Western Europe in the sixteenth century. Pope Paul III convened a council to examine the possibility of reforming some aspects of the Catholic Church as well as attempting to stem the tide of competing Christian sects that were springing up all over the country. In some ways, the Council of Trent improved the organization, but it also reinforced many of the practices that Martin Luther and other reformers found objectionable.

  • In Europe, people were experimenting with new foods and spending more time in cities, while also making strides in commerce and legal protections for some individuals.
  • Historical scholars were once convinced that the Protestant religion was a proponent of free enterprise capitalism.

Others, on the other hand, believe that Martin Luther’s other worldly interests extended to this worldly activities such as reading, in ways that aided the country’s economic progress.

This occurred in non-Protestant communities as well, to be sure.

Were they prepared to simply relinquish their position as a dominant force in European culture?

No.

A strong, even strident Catholic-Reformation or Counter-Reformation was forged by leaders among the faithful, and this movement also contributed to the advancement of commerce.

To Pope Paul the Third, who, like many other Renaissance popes, lived a life of luxury and engaged in corrupt practices such as appointing two of his grandsons to the cardinalate when they were still in their adolescent years, the task of reform fell upon his shoulders.

The great Irish poet Brendan Behan’s final words come to mind when I hear this.

Wishing you the best for all your sons.” His death followed shortly after.

Many attempts to enact reforms in formal meetings were thwarted, however, by powerful individuals who preferred the status quo to remain in place.

However, the Church had grown tired of seeing its overall power diminish, and so in 1545, the Council of Trent, which was composed of high church officials, convened to put a stop to the Protestant upsurge in the Church of England.

Certainly, I’ve sat through meetings that felt like they went on for an eternity.

As a result, among the adherents of Protestantism were some of Europe’s most powerful princes and members of the nobility, and some Catholic leaders wished to have those Protestants on their side as well.

As a result, the Council of Trent issued pronouncements that were direct and forceful.

However, the Inquisition now targeted Protestants and looked for heresy among conquered peoples in the New World, as well as within the European community.

The centrality of the Seven Sacraments was upheld in this document, and the practice of selling indulgences was maintained as well as possible.

And, unlike the Protestants, all Catholics were to continue to live by faith and do good works as their path to salvation, rather than by faith alone, as they had done previously.

Protestant reformers believed that such training was desperately needed for priests because they were being confronted by complex Protestant challenges to Catholic doctrine.

Aside from that, when the Church began to further regulate marriages, it extended its influence even further into society.

The foundations of what would become a major bulwark of Catholicism and its Counter-Reformation were being laid even before these events occurred.

A charismatic leader, Ignatius of Loyola endured spiritual agonies in the same way that Martin Luther struggled with his faith.

The Society of Jesus, also known as the Jesuits, was established by the Pope in 1540 as a religious order dedicated to Ignatius.

However, given the challenges posed by Protestantism in the 1520s and beyond, Loyola’s approach proved particularly effective.

This was all timely given the Church’s reputation for corruption and lax morals, as well as in many cases, priestly incompetence, such as a lack of knowledge of Latin language.

To complement religious instruction with humanistic education, the Jesuits established educational institutions.

And it was important because one of the attractions of Protestantism was its emphasis on broader literacy, which allowed everyone to connect directly with the Bible on a personal level.

The Jesuits are now the subject of our final point about them.

Their efforts resulted in Catholicism truly becoming a world religion, spreading to places like India, Japan, Africa, and the Americas.

To the ThoughtBubble we shall proceed.

However, they also desired to shape the way that young people learned, and thus their perspective on the world, through the establishment of educational institutions such as schools.

Learning about a subject influences how you perceive the rest of the world.

In addition, as their order spread across the globe, they modified their strategies to suit the needs of different regions.

They were successful in this endeavor.

A total of 38,000 converts to Catholicism were recorded in China by the year 1633.

Once the Jesuits established these global contacts, they produced reports, first in Latin and then in local European languages, and their work contributed to the creation of a Eurocentric globalization that eventually extended far beyond religious matters.

Although their primary mission was to spread Catholicism, the Jesuits were also active in promoting commercial and agricultural development.

Many Catholics took the Church’s reforms to heart, deepening their devotion and, in some cases, doing so in ways that helped the religion’s influence spread throughout the world even further.

Teresa of vila, a Spanish mystic and nun, was among the most well-known of them.

It’s true that I enjoy mispronouncing words, but there’s no reason to continue down this path.

But once there, she was put off by the superficiality and high society lifestyle, which included constant visits and a lot of gastronomic extravagance.

As a proponent of self-flagellation ceremonies, she believed that hitting one’s own body with a whip in imitation of Christ’s suffering on the cross was a good way to honor Christ.

Meanwhile, she set about establishing newdiscalceate Carmelite religious orders, which are characterized by their lack of shoes or bare feet, and thereby restoring austerity and strictness to monastic life.

Rather than attempting to develop nuanced or intellectual symbolism, the goal was to elicit strong emotional responses by instilling awe and portraying the might and majesty of the divine.

A dramatic atmosphere for papal rite is created by the large number of columns in the structure.

Catholicism, on the other hand, embraced imposing religious interiors, accentuating figures via the use of light and shade in paintings of Jesus, angels, and saints, and in representations of royal families around the holy.

Is it possible that the world has suddenly opened?

The Infant of Prague, or at the very least a three-dollar facsimile of it, is in fact on display.

As well as some other things.

Listen up!

You’ll know what I mean if you’ve ever read the Gospels.

While it is very Baroque in style, it is also quite religious in content, highlighting the glory of God.

For example, Bernini’s statue of Saint Teresa of vila, although it appears to be in opposition to the asceticism of refusing one’s shoes, still showed an ecstatic contact with the divine as well as an overflow of emotion and faith.

Artemesia Gentileschi was one artist who embraced the Baroque style wholeheartedly, some would say with a fury.

She herself was tortured with thumbscrews by the court in order to ensure that she was speaking the truth when her father filed a lawsuit against the perpetrator of the rape in her home.

Painting.

It is a visual and emotional experience that draws people into God’s word.

People were feverishly confronting some of the most important concerns of human life between the Reformation and the Counter-Reformation during that time period, correct?

We’re still debating faith, the Divine, and the human action that should accompany religious conviction.

Many of individuals who pioneered fresh ideas about what counts in human existence are still living in our shadow.

Which were also prominent belief systems in early modern Europe, and ones that co-existed alongside Christianity, according to the authors.

Until then, we’ll meet again.

Crash Course: World History, for example, is a great resource.

Mount St. Helens erupts

When the Protestant Reformation erupted across Western Europe, the Catholic Church finally got the message, if only in part. Pope Paul III convened a council to examine the possibility of reforming some aspects of the Catholic Church as well as attempting to stem the tide of competing Christian sects that were springing up all over the world. In some ways, the Council of Trent changed the organization, but it also reinforced many of the practices that Martin Luther and other reformers had criticized.

Furthermore, it occurred in non-Protestant communities.

Were they prepared to simply relinquish their position as a dominant force in European society?

No.

Catholic-Reformation or Counter-Reformation leaders built a strong, even strident, Catholic-Reformation or Counter-Reformation movement that also served to grease the wheels of commerce.

Pope Paul the Third was given the task of reforming the church, despite the fact that he, like many Renaissance popes, lived in luxury and engaged in corrupt practices such as appointing two of his grandsons to the cardinalate when they were still in their teens.

Also, why does this pope have grandsons, you may wonder.

He was getting an injection from a nun when he said: “Thank you, sister.

However, Pope Paul the Third recognized, in part as a result of external pressure, that the Catholic Church needed to change its ways.

This is the greatest love story of this generation or any other time in history.

And this council continued until 1563, a series of meetings that lasted so long that both Pope Paul the Third and his successor Julius the Third had died by the time it was completed.

I’m not sure if they were, to be truthful.

The Council, on the other hand, ultimately decided not to compromise.

The papacy had already expanded the work of the Inquisition, which had been established in the 13th century to stamp out heresies in southern France and Italy, while waiting for a council to be convened in person.

Transsubstantiation was also affirmed by the Council, which means that the blood and wine of the communion sacrament are believed to be the actual body and blood of Jesus.

Unlike most Protestant clerics, the clergy were expected to maintain their celibacy and chastity.

The Church also began to establish seminaries where priests could receive more in-depth training in Catholic theology, which reformers believed was desperately needed because priests were being confronted with complex Protestant challenges to Catholic doctrine.

In addition, when the Church began to further regulate marriages, it penetrated society at a deeper level.

Early on, what would become a major bulwark of Catholicism and its Counter-Reformation was taking shape, thanks to a Spanish nobleman who, after being shot as a soldier in one of Spain’s wars, took up the challenge to fortify Catholicism in the 1520s.

The Catholic Church, on the other hand, remained loyal to Ignatius and his followers, in contrast to Luther.

Many pre-existing Catholic religious orders were rededicating themselves to the protection and nourishment of their faith.

First and foremost, because he organized and managed his group in the manner of an army, with a strict hierarchy of command; joining required several years of training and adherence to a strict code of conduct.

That wasn’t an issue for the Jesuits.

In this way, the most recent developments in intellectual practice were brought together with the revitalization and reaffirmation of Catholic theology.

They believed that Catholics could also spread education, which is why there are so many Loyola Universities all over the world, as an aside.

Through them, Catholicism truly became a world religion, spreading to India and Japan, as well as Africa and the New World, among other places.

Go ahead and visit the ThoughtBubble.

The goal was not only to convert souls, but they also hoped to influence the way young people learned and, as a result, their worldview.

What you learn about shapes your perspective on the world.

As their order spread across the globe, they also adapted different strategies to suit the needs of different parts of the world.

And it was very effective.

By 1650, the population had risen to over 100,000.

For example, when it came to porcelain production, they served as an early version of industrial spies, reporting back to Europe on the processes that went into producing high-quality porcelain from China.

Thank you for your help, ThoughtBubble.

Among the most well-known was the Spanish mystic and nun, Saint Teresa of vila, who was born with a very long given name that I will not attempt to pronounce.

She left the confines of her home, where she was recovering from one of her many and lifelong bouts of illness, at the age of 20 to join the Carmelite Order of Nuns, but once there, she was put off by the superficiality and high society lifestyle, which included constant visits and upscale dining.

  • As a proponent of self-flagellation ceremonies, she believed that hitting one’s own body with a whip in imitation of Christ’s suffering on the cross was a good way to honor God.
  • At the same time, she began the process of establishing newdiscalceate Carmelite religious orders, which are Carmelite religious orders that do not wear shoes or walk barefoot, in order to restore austerity and strictness to religious life.
  • The goal was not to produce subtle or erudite symbolism, but rather to elicit strong emotional responses by instilling awe and evoking the might and majesty of the divine power.
  • A dramatic setting for papal ritual is created by the large number of columns in the building.
  • Catholics, on the other hand, embraced opulent religious interiors, enhancing figures through the use of light and shade in paintings of Jesus, angels, and saints, as well as the royalty that surrounded the divine.
  • Is it possible that the world has just opened up?
  • It is, in fact, the Infant of Prague, or at the very least a three-dollar recreation of the figure.

And I, uh, pay attention.

However, if you’ve read the Gospels, you’ll be familiar with this.

It is, on the other hand, extremely Baroque, emphasizing the majesty of God.

For example, Bernini’s statue of Saint Teresa of vila, while it appears to be in opposition to the asceticism of refusing one’s shoes, still showed an ecstatic contact with the divine as well as an overflow of emotion and belief.

Artemesia Gentileschi was one of the artists that embraced the Baroque style, some would say with a fury.

When her father filed a lawsuit against the rapist, the court tortured her with thumbscrews to ensure that she was speaking the truth.

Painting.

This artwork exemplifies Counter-Reformation art in every way, from the dramatic imagery to the stark contrast between dark and light.

& it ain’t no euphemism.

There has been much discussion about faith, the Divine, and the human action that should be associated with religious belief, and we are still not through with the ramifications of that inquiry and the replies to it.

We are still living in the shadow of people who pioneered new conceptions of what is important in human existence.

Which were also prominent belief systems in early modern Europe, and ones that co-existed alongside Christianity.

I’ll meet you at that point.

For example, you may look into Crash Course: World History.

Decades after catastrophic 1980 eruption, Mount St. Helens is ‘recharging’

— – — – — – — – — – — – — – — – — – — – — – — – — – — – — – — – — – — – — – — – — – — – — – — – — – — – — – — – After two months of growing volcanic activity, Mount St. Helens erupted on May 18, 1980, causing widespread devastation. Since Mount St. Helens’ most recent eruption in 2008, there has been an unusually large number of earthquakes that are believed to be the consequence of the magmatic system’s “recharging,” according to the Pacific Northwest Seismic Network. It was discovered that similar seismic swarms occurred during recharge periods before to a modest eruption in 2004 and during a period of volcanic activity that concluded in 2008, respectively.

  • Seismic swarms may not necessarily signal that an eruption is impending, according to the United States Geological Survey, due to the difficulty of predicting volcanic activity.
  • It claimed the lives of 57 people and destroyed hundreds of homes, 57 bridges, and almost 200 miles of roads, as well as razing tens of thousands of acres of forest in the process.
  • According to the United States Geological Survey, fine ash reached the northeastern United States two days later and circled the globe in 15 days.
  • A succession of earthquakes produced breaches in the snow and ice at the mountain’s summit, causing it to collapse.
  • Many scientists were taken completely by surprise by what transpired next.
  • on the day of the great eruption, and the mountain’s peak and part of its northern flank fell, sending a massive explosion out from the north side instead of the usual eruption from the top.
  • Streets and buildings were completely buried, and it is believed that the eruption cost $1 billion in damage.

Helens is operating at “normal background levels of activity.” “However, many earthquake swarms of modest size occurred from March to May 2016, November 2016, and April 16 to May 5, 2017, which were out of the typical.

According to Westby, these swarms are incredibly intriguing and beneficial to scientists since each geophysical signal provides them with a greater knowledge of how a volcano behaves, which is extremely important.

Mount St. Helens’ most recent eruption, which occurred in 2008, was small when compared to the catastrophic eruption that occurred in 1980.

Mount Saint Helens

Mount Saint Helens is a volcano in the Cascade Range in southern Washington State, United States. In 1980, the volcano erupted in one of the most powerful volcanic explosions ever recorded in North America, the May 18th eruption. Take, for example, the volcanic eruption of Mount Saint Helens and the resulting flooding caused by glaciers that have melted. Mt. Saint Helens erupted in a massive explosion on May 18, 1980, drawing the attention of geologists across the world. Encyclopaedia Britannica, Inc.

  • Helens had been dormant since 1857, when it was given its name by the English sailor George Vancouver in honor of a British envoy.
  • Extensive cracks and the formation of a bulge on the north side of the volcano were produced by pressure from rising magma within the volcano.
  • The earthquake was felt as far away as Alaska.
  • The blast reached temperatures of 660 degrees Fahrenheit (350 degrees Celsius) and traveled at speeds of at least 300 miles (500 kilometers) per hour.
  • Helens were submerged in deep layers of mud and debris that reached as far as 17 miles (27 km) away as a result of mudflows, pyroclastic flows, and floods caused by the avalanche and side-blast.
  • Complete darkness descended on the city of Spokane, Washington, which is approximately 250 miles (400 kilometers) northeast of the volcano.

It is not known which nation the Southern Alps are located in.

An estimated 57 humans were killed, as well as thousands of animals, in the May 18 incident, and trees covering an area of approximately 200 square miles (500 square kilometers) were blown down by the lateral air blast.

Scattered earthquakes and minor explosions happened again between 1989 and 1991 (including a few of small explosions), then again in 1995 and 1998.

Helens National Volcanic Monument was established in 1982 over 172 square miles (445 square kilometers) of land surrounding the volcano, which is maintained by the United States Forest Service as part of the Gifford PinchotNational Forest.

There are also several recreational and educational possibilities available at the monument.

There are additional possibilities to see animals and plants that have returned to the explosion zone on the west side, along with lakes that have developed as a result of the eruption on the east side.

Several lava structures of varying ages may be seen on the south side, including the longest continuous lava tube in the 48 conterminous United States, which was produced during an eruption around 2,000 years ago.

The Mount St. Helens Eruption Was the Volcanic Warning We Needed (Published 2020)

The eruption on May 18, 1980, was notable for bursting in two ways: a lateral blast followed by a column of volcanic ash that rose 80,000 feet into the air. This was the first time this had happened.

In the minutes that followed, volcanic activity wreaked havoc on the landscape, releasing eight times the amount of energy unleashed by all of the bombs detonated during World War II combined, including two atomic bombs.

Since May 7, eruptive activity has increased in frequency and intensity as the bulge has grown, sometimes more slowly, sometimes more quickly.

According to a history written by Melanie Holmes, David Johnston of the United States Geological Survey settled down for a lonely shift at Coldwater II on the evening of May 17th, 1970.

The bulge had grown to be more than a mile in diameter.

A total of 1.4 billion cubic yards of ash fell to the ground, causing damage to buildings, sewers, rivers, and electronic equipment throughout the state.

200 houses and 27 bridges were destroyed by ash-filled mudflows, which also choked rivers and lakes.

The volcano is currently ornamented with a 2.2-mile-long crater.

57 people and countless animals perished.

As the volcano’s activity increased in March, scientists had to work hard to persuade the government to limit access to everyone save law enforcement officers, volcano monitoring teams, and other important personnel.

As an echo of the events now taking place during the coronavirus epidemic, several groups objected, pointing out the negative impact the no-go zones were having on the local economy.

Archived material may be found on this page, which is no longer being maintained. At the time of publishing, it reflected the most up-to-date scientific knowledge accessible. A tremendous avalanche of rock, mud, and volcanic debris thundered down Mount St. Helens on May 18, 1980, when the volcano erupted. “Nearly 230 square miles of forest was blown down or buried beneath volcanic deposits,” according to the Mount St. Helens National Monument website’s description of the event. An ash column in the shape of a mushroom was seen rising into the sky and drifting downwind, effectively turning the day into night.” The establishment of a national monument at the location has provided scientists with the opportunity to document and analyze the regeneration of forests following such a significant disturbance.

Mount St. Helens Eruption: Facts & Information

Since then, the region has healed and returned much of its natural beauty, but it’s probable Mount St. Helens won’t stay quiet long. According to the United States Geological Survey, geologic records indicate that the volcano has gone through many periods of activity (USGS). Since at least 1800, the volcano has endured a period of intermittent eruptions until 1857, followed by a few small, steam-driven eruptions in 1998, 1903, and 1921, and a period of intermittent eruptions until 1857. Except for its 1980 eruption, the volcano had otherwise been relatively tranquil during the twentieth century and had been a popular tourist destination up until that time.

During the first week of March 1980, the University of Washington began installing a new seismic monitoring system in the Cascade Mountains, particularly near Mount St. Helens, where there had been an upsurge in seismic activity in the recent past (March 1, 1980). On March 20, a 4.2-magnitude earthquake rumbled beneath Mount St. Helens, according to the Department of Geological Sciences at San Diego State University. This was the first significant signal that serious volcanic activity was coming.

  1. Over the next few days, the shaking persisted and began to get more intense in intensity.
  2. From the air, it was possible to see fresh fissures in the surrounding glaciers as well as a large number of rock falls.
  3. Helens broke apart at noon local time on March 27, sending steam 6,000 feet (1,829 meters) into the air and smashing a 250-foot-wide crater (75-meter) through the summit.
  4. For the next 10 days, the pace of eruptions progressively rose until the volcano’s activity returned to normal on May 7.

“This is it!”

On the morning of May 18, USGS volcanologist David Johnston awoke at his campsite on a ridge 6 miles north of the volcano and radioed in his normal 7 a.m. report. The volcano was still active at the time. According to the United States Geological Survey, the alterations to the bulging mountain were similar with what had been recorded multiple times daily since the watch began and provided no indication of what was going to happen. In the early hours of the morning, a magnitude-5.1 earthquake was detected by seismographic equipment roughly a mile under the volcano.

  1. The ridge he was camping on was within the explosion zone, and it was his final message before he died.
  2. The whole north face of the mountain was engulfed in flames in a matter of seconds.
  3. They were stranded in the mountain for several hours.
  4. The sudden release of pressure above the magma chamber resulted in the formation of a “nuée ardente,” a brilliant cloud of superheated gas and rock debris that was pushed out of the mountain face at speeds approaching supersonic velocity.
  5. The tremor continued to roll across the forest for another 19 kilometers, uprooting century-old trees that had been precisely oriented to the north until they were all leveled.
  6. It was roughly 230 square miles of land that was damaged by the direct blast energy of the explosion (596 square kilometers).
  7. This explosion happened shortly after the first.
  8. The heat from the original eruption melted and eroded the glacial ice and snow that had accumulated around the volcano’s remaining portion.
  9. According to the United States Geological Survey, the lahars reached speeds of 90 mph (145 km/h) and completely destroyed everything in their path.

Helens melted as well, and this certainly contributed to the damaging lahars, according to an email from Live Science. Trees were knocked down as a result of the lateral blast. (Image courtesy of the United States Geological Survey; author contributed.)

Most destructive U.S. volcano

The eruption of Mount St. Helens in 1980 was the most damaging in the history of the United States. According to the United States Geological Survey, 57 humans died and countless of animals were slaughtered. More than 200 homes were destroyed, and more than 185 miles of roads and 15 miles of railways were damaged as a result of the disaster. Ash choked sewer systems, caused damage to automobiles and buildings, and caused aviation travel over the Northwest to be briefly halted. The International Trade Commission reported that the forestry, civil construction, and agriculture industries had suffered losses totaling $1.1 billion.

Will Mount St. Helens erupt again?

Scientists are keeping a careful eye on Mount St. Helens and other volcanoes in the Pacific Northwest at the present time. Because of the volcano’s placement on the Cascadian Subduction Zone, another eruption is almost certain, according to Howard R. Feldman, head of geology and environmental science at Touro College in New York, who spoke to Live Science. However, forecasting when anything like this would occur is quite difficult. According to Edwards, long-term seismic data is essential for determining when a volcano may be on the verge of exploding.

According to data from the Pacific Northwest Seismic Network, seismic activity in the area surrounding Mount St.

40 Years Ago: Lessons From the Eruption of Mount St. Helens

From the October 1980 Issue

“There was no sound coming from the mountain, just those gentle-looking puffs of steam,” recalls photographer Michael Lawton of his early-morning journey to capture Mount St. Helens in mid-April. “It was a peaceful morning,” he adds. In spite of the warning signs, which included white fumes rising from the peak, Lawton was unfazed: “I recall thinking to myself that this would be a fantastic spot to see it erupt.” Lawton and his local mountain guide had hiked for five hours up icy slopes to reach their mile-high observation position, which was around eight miles away from the smoking mountain.

  1. If they had arrived a month later, on May 18, the date of the volcano’s most explosive eruption, they would have had just seven minutes before being swamped by an onrushing wall of hot gas, ash, and rock.
  2. Lawton returned four months later to a location within a few hundred feet of the same location to capture another photograph.
  3. It’s not exactly barren, but it’s close.
  4. Helens as a natural laboratory for probing the inner workings of an active volcano.
  5. Each earthquake is recorded by their seismographs, while instrument-laden planes soar through the rising plumes and satellites stare down at the ash-filled atmosphere — all in an effort to profile the mountain’s distinct personality and character.

Those months of volcano-watching are beginning to bear fruit, and As a result of their work at the site, geologists have amassed an impressive track record in terms of predicting the sequence of mild eruptions that have happened since the May 18 blast.

  • “We’ve had some seeming achievements, but the real test will be whether or not we can build on them in the future.” Seismic activity remains to be the most important instrument in earthquake forecasting.
  • Helens, are preceded by harmonic tremors, which are rhythmic movements of the ground believed to be generated by magma (molten rock) moving deep beneath the mountain.
  • Four hours later, Mount St.
  • The bulges on the volcano are just another indicator of impending violence.
  • “We see a swelling pattern just before an eruption,” says Lipman.
  • Scientists discovered that the mountain’s north flank was expanding at a rate of up to six feet per day before the major eruption in May.
  • Since then, the daily deformation has been measured in fractions of an inch at a time instead of inches.

During the eruptions on July 22 and August 7, for example, scientists noticed a shift in the ratio of carbon dioxide to sulfur dioxide in the gases being emitted.

However, for many days leading up to the August 7 incident, the ratio progressively decreased, reaching around three to one — for reasons that scientists are still trying to figure out.

“The gas emission rate from Mount St.

When the magma has expelled all of its gas, the mountain may begin to flow lava (as seen in the familiar Hawaiian volcanoes) rather than exploding explosively, as it has done in the past.

“The geologic record of Mount St.

Helens has a diverse range of capabilities.” “It’s likely to repeat the same actions that it has done in the past, but it might also introduce some new ones,” says the analyst.

Helens does, the United States Geological Survey (USGS) predicts that it will continue to erupt for an extended period of time.

The agency has sought more than $11 million in funding from Congress in order to continue monitoring not only the one active volcano in the United States, but also the other potentially explosive mountains in the Cascade range in the Pacific Northwest.

2020 Hindsight: After the Blast

When Mount St. Helens erupted in a sideways explosion on May 18, 1980, the resulting dust did not settle immediately. Immediately following the fall of the volcano’s peak due to a 5.1-magnitude earthquake, which created the greatest landslide in recorded history, an explosion of ash, debris, and hot gas erupted from the volcano’s north side at speeds exceeding 300 miles per hour. The shock wave leveled the surrounding forest, and mudslides wiped out hundreds of dwellings in the surrounding area.

In all, 57 individuals died as a result of the eruption, the majority of them suffocated as their lungs were clogged with volcanic material.

Helens was transformed into a live laboratory for the study of volcanic activity in the midst of the disaster.

In this particular instance, an earthquake created a landslide, which in turn depressurized the magma beneath the surface of the Earth’s crust.

It also prompted volcanologists to refine their monitoring efforts in order to aid in the prediction of volcanic eruptions.

For decades, ecologists have utilized the volcano to investigate how life survives — and even thrives — in a once-devastated environment, and they continue to do so today.

Even though acres of trees were felled by the blast, the avalanches of debris created two new lakes and more than 150 new ponds in the area.

Is it possible that scientists in 1980 would have been able to prevent the damage wreaked by Mount St.

Helens if they had known what we know now? It’s possible we’ll never know. The fact that science is still learning from the volcano’s great moment 40 years later is apparent – from volcanology to ecology to public health, to name a few areas of study. Alex Orlando is the author of this piece.
