Mount Saint Helens Devastates the State of Washington The 1980 Eruption of Mount Saint Helens was a moment to remember in history. The eruption of Mt St. Helens was devastating. The damage done costed lots of money. The eruption was huge and blew lots of ashes into the air and forest. Many people and animals died. The skies remained dark for days. It is by far the most destructive and violent volcano recorded in North America (Bagley). Mount St. Helens had been dormant for as long as we can…

There are many different aspects in the world of geology. Something that I want to focus on are hydrothermal vents. Hydrothermal vents are like chimney shaped hot springs that are located on the ocean floor. Hydrothermal vents were first discovered in 1977 near the Galapagos Islands in the eastern Pacific. Scientists exploring the area along the mid-oceanic ridge had noticed drastic temperature changes in their data. With the help of ALVIN, a research deep sea submersible, they discovered vents…

Mount Cleveland is one of Alaska’s most active volcanoes. It has erupted more than 20 times in 230 years. Mount Cleveland is a nearly symmetrical, stratovolcano on the western end of Chuginadak Island, which is part of the Islands of Four Mountains. The Islands of Four Mountains are just west of Umnak Island in the Fox Islands located in the Aleutian Islands of Alaska. In 1894 a team from the U.S. Coast and Geodetic Survey (formerly the United States Survey of the Coast) visited the island and…

Explosive volcanoes are one of the most dangerous natural occurrences on the planet, but the types of volcanoes that can destroy the world are know as super volcanoes. Super volcanoes are determined by past explosion and this volcano can be located in the United States called Yellow Stone. Their criteria also depend on the volume of an eruption, for a super volcano the eruption must be more than 240 cubic miles of pumas and ash. There had been three super explosions that fit the criteria at…

Mount ST. Helens The eruption of Mount ST. Helens changed people’s lives because it destroyed everything in its path. The volcano erupted at 8:32 a.m. on May 18, 1980. The eruption caused snow on the mountain to melt and the snow flooded the roads and bridges. The eruption sprayed a thick layer of volcanic ash over a huge area. If you do not know what Mount ST. Helens is, well it is a volcano that erupted in the year 1980. Mount ST. Helens is located in the Cascade mountain ninety-five miles…

There are some good things and some bad things about how volcanoes affect our environment. Here are some things that a volcano can affect: soil, air, and the climate. How do volcanoes affect people and their environments? In some cases living by a volcano would be bad because of what it could cause. Living close to the vent of a volcano can be a dangerous hazard because the vent releases gases that could cause health problems. It is undetermined when a volcano will erupt. About 60 volcanoes are…

The Mount Tambora volcanic eruption commenced on April 10 1815, on Sumbawa one of the many Lesser Sunda Islands in Indonesia. Mount Tambora is one of the many volcanoes in the ring of fire and the only volcano in recorded history to reach a volcanic explosivity index (VEI) of 7. On the day of the eruption the explosion was heard from approximately 2000 kilometres away among the Sumatran islands. Mount Tambora is described as a Stratovolcano a large volcan layered within with ash and magma form…

1. Mount Fuji: Mount Fuji is the highest mountain in Japan, soaring to well over 12,000 ft! It is also an active volcano, and considered to be one part of Japan’s trilogy of Holy Mountains. It is indeed considered a sacred spot, and those who brave the strenuous climb to the summit are sure to come across many make-shift shrines that have been erected along the way. Be sure to visit Hakone, a resort located at the mountain’s base that offers road-weary hikers the opportunity to take a luxurious…

Yearly, there are fifty to sixty volcanoes erupted. Within the year, two tsunamis devastate, and several million earthquakes befall upon the planet. These are geoprocesses, all of these affect Earth’s surface and the inhabitants thereof. Earth’s surface changes through geoprocesses including volcanoes, earthquakes, and tsunamis. Firstly, volcanoes are one example of geoprocesses that affect earth’s surface. Volcanoes happen when tectonic plates sink down into the mantle, made up of molten rock,…

It is concluded that Yellowstone will someday erupt again however, it might not be in the near future. With the myriad of tourists that visit the National Park every year, they had to be sure that it wouldn’t explode soon to ensure people’s safety. Geologists have found that the ground around where the volcano is, is now swelling. The swelling indicates that the underlying magma chamber is refilling once again. But people have other questions, how was this volcano formed? Usually volcanoes…
