Of the volcanoes that are located in the United States there are two which are world renowned for their activity and their power to change the region surrounding them. The two volcanoes would be Mount Saint Helens and Mount Kilauea. In order to get a better understanding of these volcanoes we will be comparing and contrasting them as well as talking about how they were formed and when they last had an eruption.

Kilauea is a volcano in the Hawaiian Islands it is one of the five shield volcanoes in the Hawaiian language Kilauea means spewing or spreading. Mt St. Helens is an active stratovolcano in Washington it is named after British diplomat lord st Helens.

There is an assortment of geologic activity at Yellowstone and Hawaii. At Yellowstone there are 1,000-3,000 earthquakes per year at Yellowstone. There are also over 10,000 thermal features found in Yellowstone (Volcano Questions & Answers). In Hawaii Mauna Loa and Kilauea are regarded as active volcanoes. Mauna Loa last erupted in 1984 and scientist predict this volcano will erupt again in the future. Kilauea is the world most active volcano and has been continuously erupting since 1983

The basic theory of plate tectonics says that all volcanic activity should occur between lithosphere plates (Physical Geology). However, the Hawaiian Islands bend this rule by being located directly in the middle of the Pacific plate. The Hawaiian volcanoes are known as intraplate volcanoes. This may not seem possible because it disrupts the rule of plate tectonics, but there’s the exception of a hot spot. T. Wilson suggested that the Pacific plate moved in the northwestward direction over a melting spot deep within the mantle, and this hot spot remained relatively stationary and supplied magma to the moving Pacific plate to form the Hawaiian Island chain (Volcanoes in the Sea). In order to prove this suggestion, the structure of the Hawaiian Islands must be in line with a hot spot origin. This will be

Volcanoes are one of the most destructive, yet, most beautiful things on Earth. They can make a famous city choke in its own ashes in one day, like Pompeii. Or they can turn a once damaging mountain into a graceful and peaceful home for new life, like Mount St. Helen’s. All volcanoes are unique, and no two are the same. Some erupt differently than others, some look different than others, and all are located in different spots all over the world. I learned this while completing the project and the five volcanoes I researched are examples of my discoveries. The five volcanoes I researched were Mount Hood, Mount Mageik, Long Island, Mount Muria, and Las Pilas.

In the early 1900s St.Pierre on the French Caribbean island of Martinique was famous tourist destination.”It was known as the Paris of the west Indies”, and home to more than 20,000 people,Mount Pelee sits about 4 miles from St Pierre.On May 8, 1902 the volcano erupted. Sending a volcanic surge directly at St.pierre's at a rate of 420 miles per hour.Killing 30,000 people in its wake.National National Geographic News”Deadliest volcano of the 20th century, 100 years later””molly pell and channo wOodage for National Geographic News, 5-8-2”

The location of the volcano is also important. If it is situated on a constructive plate boundary then it is generally less explosive, and therefore poses different threats to volcanoes situated on a destructive plate boundary. The volcano may also be situated on a hotspot like in Hawaii, where the eruptions aren’t very explosive. Volcanos which aren’t explosive can pose other threats to lava flows though, such as dangerous gases being released. Like in Lake Nyos, Cameroon where 1700 people died.

Mount Rainier is located in Washington, and it basically dominates the landscape of a large part of western Washington. The mountain is 4,329 meters, and it is what

Mauna Loa volcano. Mauna Loa is an active, large, and dangerous volcano in the world.this volcano can cause more than one damage. Mauna Loa affects people’s lives, and damages lands. Mauna Loa is a magnificent force of nature.For centuries Mauna Loa has captivated many discoverers and scientists all around the world.But some, however got injured by Mauna Loa and didn’t study its parts.One discoverer however actually discovered it somehow.This volcano is very dangerous and it can damage 1 small village.

Since 1882, Mauna Loa has erupted 39 times. This volcano is a outstanding force of nature. Mauna Loa has amazed many people for mann years. This is a shield volcano, located on the beautiful island, Hawaii. As the Earth’s plates move, it causes more and more volcanoes to erupt. Mauna Loa is a breath-taking phenomena.

There was a time when the caldera was finally cooled, allowing the rain and the snow accumulation melt water to form the lake. Landslides from the caldera rim thereafter formed debris fans and turbidite sediments on the lake bed. During this period, fumaroles and sources of thermal waters were common and remained active. After some time, the slopes of the caldera stabilized more or less, the streams restored the radial drainage system of the mountain and began to sprout dense

Ash plumes and steam rose into the bright blue sky as the underground earthquake shook the land and rattled windows all across the eighteen mile town. As the jet circled the island, in view of lovely beaches and emerald water, looming over this lush paradise was the screaming volcano. Volcanos erupt when the pressure inside of them becomes so great that the magma surges up and forces its way out. An exploding volcano can rip apart a mountain in just seconds, when the eruption is over, a landscape is changed forever. The united states is home to more volcanos than any other country except Indonesia, and Japan. The majority of these volcanoes are in Alaska. Until recently, there was no way to predict when a volcano would blow, although volcanoes give off many warning signs before they erupt. Including smaller earthquakes beneath the volcano, slight inflation, or swelling. The rising magma eventually causes the solid rock to break, sending earthquake signals. Most volcanoes give warning signs beginning weeks or months before they blow (Lindop).

In 1982, J. BRUCE GEMMEL climbed this volcano, and gave a vivid description to several volcano experts, including McClelland (1989). He described the main cone as HEAVILY VEGETATED with a great number of COLLAPSED CRATERS from the East Northwest, and West, Southwest. In addition, Gemmel stated that the most active of the three main craters actually included A LAKE OF ACID that spanned 500 meters wide! This lake is a GLOWING BLUE COLOR. The glow is caused by sunlight reflecting from ash and chemicals suspended in the
