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
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.
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 ...
Lassen Peak and Mount St. Helens are the only two volcanoes in the contiguous United States to erupt during the 20th century.
Volcanic forecasts are more accurate then earthquake predictions. These predictions are generally forecast in the same way as an earthquake (temperature increases in geothermic waters gaseous concentrations, changes in elevation of land and water etc… Because we generally know where Volcanoes are, we can predict when an eruption may take place.
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...
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.
Volcanoes. The naturally forming landforms that can look remarkably beautiful. Gentle slopes, or high rising heights with snow caps and greenery that seems to attract many tourists and sightseers around the world. These magnificent landforms can also cause major destruction and can produce forces that can explode, burn, and create a great deal of damage. Two of these extravagant wonders of the world is the Mount Saint Helens composite volcano in Washington, US, and the Mauna Loa shield volcano in Hawaii, US. These landforms have a eruption history of many colors. One has a great power in eruption, but another has a eruption that is quiet and gentle. In comparing these two volcanoes there are many likes, and dislikes, to consider. So the following
Stories about volcanoes are captivating. Myths come in different versions, but all of them are capable of capturing yours, and everybody’s imagination.
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.
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
It is known however that lying underneath one of America's areas of great natural beauty, Yellowstone Park, lays one of the largest super volcanoes in the world. Scientists have discovered that it has been on a regular eruption cycle of 600,000 years. The last eruption was 640,000 years ago, therefore this shows the next eruption is late and could erupt at any moment. Scientists know that the collision of a Yellowstone eruption is terrifying to understand.
Volcanoes are one of the most destructive forces on Earth. It is estimated that some 500 million people live near active volcanoes (Lutgens and Tarbuck, 2013). Of the Earth's known volcanoes, 70 are expected to erupt each year with at least one large eruption each decade (Lutgens & Tarbuck, 2013). As populations continue to increase and more people are attracted to the beauty surrounding these areas, the immediate threat to humans from these sometimes sleeping giants grows. Due to this, the study of volcanoes and the service that volcanologists provide to the public by way of information and predictions on activity is immeasurable.
Dante’s Peak Critical Analysis: Pop-Culture and Geology Many movies depict natural disasters and over dramatize them. Dante’s Peak may not be perfect in how it portrays volcanic activity, but it does a pretty good job. It captures a lot of the real life drama that would ensue during an eruption. It mentions real geological terms that we have learned about in this class.
