Mount Shasta Term Paper
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.
First, one must know a little information about this volcano. Mount Shasta is located in Siskiyou County, California. This volcano is the second highest peak in the southern end of the Cascade Range and is still active, though not enough for people to notice. At 14,179 feet it is also the most voluminous stratovolcano located in the Cascade Volcanic Arc. The mountains complex shape is due to the four overlapping volcanic cones it consists of, including the most prominent, main summit, Shastina. The other cones include: Sargents Ridge cone, Misery Hill cone, and Hotlum cone. Sargents Ridge cone is the oldest of all the cones that make up the mountain. Though it is now dissected by a glacial valley, a portion of it can still be seen on the mountain. Misery Hill makes up a large part of the present mountain. the fourth cone, the Hotlum cone is formed from eruptive products and is located on the northeastern side of Mount Shasta. Three of the four major vents on the mountain are aligned with a north trending zone that passes through the mountains summit. This linear alignment parallels local faults, which suggests that the bedrock structure has influenced and partially controlled the dimensions in which Mount Shasta develops (Mie...

...gh Mount Shasta is a beautiful mountain with great hiking spots for tourists, it is also a big threat to surrounding cities. This volcano poses the threat of pyroclastic flows, debris flows, lahars, and tephra. The prevalence of many of these hazards isn't very high, however the threat they pose is very serious and isn't taken lightly.

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.

Mt Fuji is a symbol of Japan: contributing to physical, cultural and spiritual representation of Japan. Fuji is also known as one of the three ‘holy’ mountains along with Mount Tate and Mount Haku Fuji stands 3776 meters (12380 feet). It’s still an active stratovolcano and sits on a triple junction of tectonic movement. Fuji is approximately 100km (62 miles) from the largest city and the capital of Japan, which is Tokyo. The last time Fuji erupted which was between 1707 and 1708, volcanic ash fell on Tokyo. Lately the volcano has experienced a rise in popularity from Japanese locals, tourists and artists. Around 2000 and 2001 Japan experienced seismic activity under the volcano and levels were slightly higher than usual, uplifting the concern for the reawakening of the volcano.
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 ...
Boom! A once ice-capped mountain peak explodes as ash fills the air. “‘Vancouver, Vancouver, this is it!’”Those were the last words of expert geologist David Johnston (Gunn 561). In 1980, Mount Saint Helens of the state of Washington erupted, filling the air with ash and causing mudflows powerful enough to lift tons. It decimated everything in its path. The eruptions, mudflows, and ash caused great damage on the landscape, yet it gave us information on how catastrophes happen and how they affect society and the surrounding landscape. The data acquired can also help us understand the way the landscape was formed. Mount Saint Helens caused much damage, but also helped people understand the science behind it.
Mount St. Helens is an active stratovalcano in Skamania County, Washington, in the Pacific Northwest region of the United States. It is located 96 miles south of Seattle and 53 miles northeast of Portland, Oregon. The mountain is part of the Cascade Range. It is most famous for a catastrophic eruption on May 18, 1980. That eruption was the most deadly and economically destructive volcanic eruption in the history of the United States. 57 people were killed, and 200 homes, 47 bridges, 15 miles (24 km) of railways and 185 miles (300 km) of highway were destroyed. The eruption blew the top of the mountain off, reducing its summit from 9,677 feet to 8,364 feet in elevation and replacing it with a mile-wide horeshoeshaped crater.
On May 18th, 1980, one of the most prominent volcanic eruptions in US History took place in the state of Washington. Mount St. Helens had been dormant for almost 100 years before March 15th. On this day, two months before the eruption several small earthquakes shook the earth. 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. Within a week the crater had grown to about 400 m (1,300 ft) in diameter and two giant crack systems crossed the entire summit area. Eruptions occurred on average from

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 be one of the most destructive forces on Earth. It is estimated that some
The Mauna Loa volcano is located in Hawaii and means "Long Mountain" in Hawaiian. It is a giant, basaltic shield volcano. It is one of the largest volcanoes and mountains in the world and has been called the "monarch of mountains". It has an estimated volume of 9,600 cubic miles and takes up half the land of Hawaii. It extends about 120 km starting from the southern tip of the island to the northern region. It is 97 km (60 miles) long, 48 km (30 miles) wide, and is 8,742 km (28,680 miles) high from the base on the sea floor to the top. The slopes are steeper than 12 degrees and about 4 degrees at the top of the volcano. Mauna Loa formed about half a million years ago and in the middle stages of forming into a shield volcano where lava flows to form a sloped and broad flat domed volcanic cone. Along with Mauna Kea, the Mauna Loa volcano is responsible for the creation of the Hawaiian Islands. Mauna Loa has erupted thirty-three times since 1843 and is known as one of the most active volcanoes in the world today. The last eruption was 1984 and lava flowed within 4 miles of the city of Hilo. This shows that it is dangerous to live anywhere near Mauna Loa and that it poses as a threat to anyone living near it because it has a very high possibility of erupting within a very short span of time. Below is a picture of Mauna Loa taken from a bird's eye view.
The earliest outcropping volcanic deposits date back to about 25,000 years ago. The lavas observed at a -1125 m bore-hole are about 0,3-0,5 million years old. It is known for the first eruption of which an eyewitness account is preserved, in 79 AD. Geologically, Vesuvio is unique for its unusual versatility. Its activity ranging from Hawaiian-style release of liquid lava, fountaining and lava lakes, over Strombolian and Vulcanian activity to violently explosive, plinian events that produce pyroclastic flows and surges.
