Research Paper On Mount St Helens

This indicated a magma buildup below the surface, and the first minor event that would lead to one of the greatest eruptions the US has ever known. Following the first set of earthquakes, “Steam explosions blasted a 60- to 75-m (200- to 250-ft) wide crater through the volcano 's summit ice cap and covered the snow-clad southeast sector with dark ash.

The 1815 Eruption of Mount Tambora
2292 Words | 5 Pages...815 eruption of Mount Tambora. With over 70,000 deaths and a rating of 7 on the volcanic exclusivity index, this eruption is one of the largest in recorded history. Not only did this volcano cause destruction in Indonesia but the consequences were further felt around the world, as volcanic ash and sulphuric gases were dumped into the stratosphere causing a global climate shift. Dark clouds covered the sun, and dramatic weather changes ensued. Flash floods frequently occurred wiping out a great deal of crop eventually causing prices to skyrocket. Disease began to spread due to malnourishment and unsanitary living conditions. Eventually these consequences subsided and citizens began to migrate towards Mount Tambora once again. Today the government has placed seismic sensors are set up in the most volatile areas to ensure preparedness in the event of another volcano.
Mt. Rainier
1413 Words | 3 PagesThe 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.

Mount Etna Volcano Essay
1013 Words | 3 PagesThe volcano of Mount Etna has been on this earth for about 500,000 years and is still currently active. This volcano is located on the east side of Sicily, Italy and stands 10,900 feet tall with a base circumference of 93 miles; it also still has a series of eruptions dating back to 2001. Mount Etna is considered a stratovolcano which means it’s built on top of many layers of lava and ash made from previous eruptions. What makes this volcano so unique is that it has many eruption styles ranging from extreme violent ones to regular lava just flowing from the mouth of it. About “25% Sicily 's population lives on Mount Etna 's slopes.”
Volcanoes and Volcanology
2115 Words | 5 PagesVolcanoes 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.
Volcano Mount Vesuvius

The Somma-Vesuvius complex has formed over the last 25,000 years by means of a sequence of eruptions of variable explosiveness, ranging from the quiet lava outpourings that characterized much of the latest activity (for example from 1881 to 1899 and from 1926 to 1930) to the explosive Plinian eruptions, including the one that destroyed Pompeii and killed thousands of people in 79 A.D. At least seven Plinian eruptions have been identified in
