Dante’s Peak Questions:
General questions about volcanoes and volcanologists:
How many active volcanoes are there on Earth?
There are 1500 potentially active volcanoes worldwide.
How many active volcanoes are the in the United States?
There are approximately 169 active volcanoes in the United States.
Is it possible to predict an eruption’s time, place and character?
Yes, by examining a volcano's history, how long since its last eruption and its time span between its previous eruptions. We can also look to smaller earthquakes which indicate that magma is moving underground. Some other factors include slope deformation of a volcano and an increase in gas emissions.
Movie fact of fiction:
Is the eruption depicted in Dante’s Peak

The volcanic eruptions at stratovolcanoes, in the Cascade Range, are explosive and produce pyroclastic flow and clouds of volcanic ash, which the movie does show realistically. However, the lava flow in the movie is very fluid when in reality the lava flow at stratovolcanoes is viscous and therefore slow moving.
Can eruptions really threaten helicopters, as in the movie and other aircraft?
Yes, helicopters and other aircraft can be damaged by volcanic ash. When aircraft accidentally encounter volcanic ash clouds, jet engines can temporarily lose power. In the movie, people were climbing into the helicopter in hopes of escaping, however; the aircraft caught on fire and exploded.
Can a town’s water supply become contaminated when a volcano is restless?
Yes, the water supply could be contaminated if a town’s water supply directly originates from a volcano’s groundwater system or if the water supply comes from a stream that has been covered in volcanic ash. In the movie, when the mayor tried to get water from the sink, the water was brown, so they went to check on the town’s water supply and found lots of sulfur in the water.
Questions about eruption precursors:
What kind of unusual activity might be noticed before an
In March 18, 1880 Mount St. Helens there was a catastrophic eruption that caused a huge volume of ash; the ash plume would be over central Colorado within 16 hours. After years of dedicated monitoring (knowing where to volcano is, unlike an earthquake not knowing exactly where this geological even is exactly) there was been increasing accuracy in forecasting eruptions.
On May 22, 1915, an explosive eruption at Lassen Peak devastated nearby areas and rained volcanic ash farther 200 miles to the east! This explosion was the most powerful in a series of eruptions from 1914 through 1917. ...
The first time I saw Mt. Rainier for myself, was last summer when my boyfriend and I drove to Washington. It was the most beautiful, peaceful looking mountain I have ever seen. However, underneath it's great beauty, it hides a deadly secret. Mt. Rainier is one of the most dangerous volcanoes that we have here in the United States. One of the reasons it is so dangerous is because of it's great beauty. People enjoy looking at it, and the area that surrounds it, so they have made their homes here. Mt Rainier is not the only volcano I am interested in, in fact this last summer I also went to Mt. St. Helens and Crater Lake. But it is the volcano I chose to research for this paper because it does have so much beauty and at the same time so much power. I already know the basics about volcanoes, how they form, the different types, etc., but I wanted to find out more about what would happen if this great volcano were to erupt, what type of eruption would it be, and how would it affect the people that live around it.
Although volcanoes are difficult to predict, geologists have made many efforts in order to caution the people of Orting and other surrounding towns of possible lahar slides. Residents have been made aware of emergency response plans and they know the proper precautions to take in the case of a volcanic activity emergency. Sirens have been put into place by the fire department and governing bodies of surrounding communities that detect volcanic activity and warn the community of ...
Many of us know Mount Shasta to be a beautiful mountain and a popular tourist location in California. However, this mountain is much more than that, this mountain is actually a volcano. Volcanoes come with a number of hazards and a volcano of this size is of no exception. Previous eruptions on Mount Shasta have given us an idea of the power this volcano has and the damage it may do. With this information scientists are able to predict what may happen should another explosion occur.
The eruption on Mount Saint Helens has a specific cause and comes with many effects. A multifold of people would say that the “mountain looked like the site of an atomic blast” (Bredeson 30). That is a very accurate depiction as it took great power to inflict as much damage as it did. The reason for this impressive amount of force is that when magma is built up with pressure and an earthquake hits, the pressure gets magnified and the volcano explodes (Lewis). This is exactly what happened inside Mount Saint Helens. Furthermore, it has been revealed that “The earthquake that triggered the explosion was a 5.2 on the Richter scale” (Gunn 559). The earthquake to the magma can be compared as a match to gasoline. Even though the earthquake was not huge, the scale of the eruption was much greater than that of the earthquake (Gunn 560). The earthquake was only the trigger that allowed for more devastating things to occur. Thirteen hundred feet of the volcano were lost in the explosion followed by landslides, mudslides, and lava flows...
Not all of the eruptions are on track with actual volcanoes, but they do use correct terminology. Some of the effects in the movie are similar to reality. A car driving across molten lava would obviously not go anywhere. It would immediately erupt into flames and there would be no survivors. I do hope that nobody would actually try to drive across lava.
These differences are in the makeup of the volcano, the impact on society, and the eruption itself. Mount Saint Helens, used to be a wonder of the world, but now a damage site of what happened on May 18, 1980. Mauna Loa is a tourist destination and one of the most active dispensers of lava and magma in the world. As shown, these volcanoes can’t be more different. Yet, each volcano has been a culprit to destruction, and have similarities within themselves. This report has expressed many similarities and differences and brought facts and knowledge to the historical eruptions by these impressive and ancient structures of
Dante’s The Divine Comedy illustrates one man’s quest for the knowledge of how to avoid the repercussions of his actions in life so that he may seek salvation in the afterlife. The Divine Comedy establishes a set of moral principles that one must live by in order to reach paradiso. Dante presents these principles in Inferno where each level of Hell has people suffering for the sins they committed during their life. As Dante gets deeper into Hell the degrees of sin get progressively worse as do the severity of punishment. With that in mind, one can look at Inferno as a handbook on what not to do during a lifetime in order to avoid Hell. In the book, Dante creates a moral lifestyle that one must follow in order to live a morally good, Catholic
Stories about volcanoes are captivating. Myths come in different versions, but all of them are capable of capturing yours, and everybody’s imagination.
When the reservoir has formed, a substance is collected that will trap the volcanic gases. They form depressions in the ground and it is very hard to imagine the eruptions, explosions, car atrophic proportions that they cause. Super volcanoes produce vast amounts of ash and destruction. There are thousands of normal volcanoes around the world and at least 50 erupt every year. Vast clouds of ash are deafening sounds; it affects the climate on earth for many years and affects the agriculture colour.
Volcanoes can be one of the most destructive forces on Earth. It is estimated that some
Volcanoes can cause damage by spewing lava, but earthquakes before the eruption can also cause damage. These earthquakes open fissures and let magma out to the surface. When the magma exits these fissures, streams of lava up to hundreds of feet can shoot into the air. The picture below shows the lava erupting from the fissures created by the earthquakes in...
“Midway along the journey of our life” (Canto 1) Dante the Pilgrim says at the beginning of his journey. Through out the comedy and the Pilgrims vision of hell, I believe he was truly on a journey of self-discovery. Dante encountered a guide to help him in his journey throughout the nine circles of hell. Going deeper and deeper into hell Dante realized many different sins that he could have committed in his life and realized the things that he did not need anymore. Base on the end of his journey I believe that Dante truly found himself and found a new person within himself.
