Comparing Mt. St. Helens to Kilauea

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.

The Kilauea Volcano is the youngest and most active Hawaiian shield volcano. This volcano is located on Hawaii’s Big Island. The volcano is part of the Hawaii Volcanoes National Park. Kilauea is 300,000 to 600,000 years old. The native people from the Polynesian Islands discovered Kilauea. The other four volcanoes of Hawaii are Kohala, Mauna Loa, and Mauna Kea.

Mount St Helens erupted on the 18th May 1980 at 9am and is an active strata volcano Washington State USA, a MEDC. Where as on 18th July 1995, during the daytime, Montserrat, a LEDC during the day, Montserrat's Soufrière Hills composite volcano of a height 1050m, meaning sulphur hills, dormant for centuries, erupted and produced a phreatic eruption. The volcano is a strata volcano also. Mount St. Helens is a composite volcano which lies near to a destructive plate boundary where the small Juan de Fuca Plate is being subducted underneath the North American Plate where as the eruption

Many people go to Hawaii for a nice relaxing vacation, not knowing they’re right next to one of the five most active volcanos in the world,Kilauea. Kilauea had killed over 400 people in a single eruption. Kilauea is formed on a hotspot,or a place of significant activity or danger,this is one of the reasons Kilauea is so active. Kilauea has had many small eruptions, but the last large eruption lasted 30 years and was from 1983 to 2013. Kilauea may seem like any other regular volcano but it is much more dangerous.

Mount St. Helens Location: Washington, United States Latitude: 46.20 N Longitude: 122.18 W height: 2,549 meters or 8,364 feet - 9,677 feet before May 18, 1980 Type: Stratovolcano Number of eruptions in past 200 years: 2-3 Latest Eruptions: Between 1660-1700, around 1800-1802, 1831, 1835, 1842-1844, 1847-1854, 1857, 1980-? Present thermal activity: strong steaming Nickname: Mount Fuji of the West Remarks: continuous intermittent activity since 1980 with occasional eruptions of steam and ash; occasional pyroclastic flows; intermittent dome forming. MSH is considered a young volcano that developed over the last 40,000 years and is one of the most active volcanoes in the Cascade Range. Geologists predicted that the

Mt St Helen May 18th, 1980 the erosion rose 80,000 feet making ash go to 11 U.S states making snow, ice, and glaciers melt forming volcanic mud slides that reached as far as the columbian river (50 miles to the south east) 57 people died in washington.

It was May 18th, 1980. The eruption of Mount St. Helens occurred in Washington,United States. The exact time it had happened is at 8:32:17. The eruption happened 96 miles out South of Seattle, Washington and 50 miles northeast of Portland,Oregon. Many people died during this time. About 50 people had died. 250 homes were destroyed. Along with 47 bridges, 15 miles of railways, 185 miles of highway was also destroyed. Many tiny earthquakes had happened a couple days before the eruption had happened.

Mount St. Helen is a very active volcano classified as a stratovolcano, stratovolcano is basically a tall volcano built up of layer after layer of hard lava, tephra, pumice, and volcanic ash. Mount St. Helens location is in Skamania County in Washington, with coordinates of 46 12'00.17"N122 11'21.13"W. Mount St Helen is famous because of its catastrophic eruption on May eighteenth in nineteen eighty. The eruption measured a five on the volcanic explosivity index. This is an index created by Chris Newell and Steven Self in the year nineteen eighty-two it was designed to try and measure the explosiveness of volcano eruptions to determine the value of the explosivity and qualitative observations ranging from zero to eight, eight being the

Kilauea volcano is one of the most active volcanoes in the world. Kilauea means spreading or spewing for its frequent lava flows (USGS, 2014). It is a shield volcano that locates on the southern of the Big Island in the Hawaii island chain at 19o25’16” N-155o17’13” W with the elevation of 4190 feet above the sea level. The island chain forms by the movement of the Pacific plate over the stationary hot spot (Bagley, 2014). Kilauea is the youngest volcano due to its location on the most southern where a hot spot is very active (Volcano discovery, 2014).

As the youngest and most southeastern volcano on Hawaii 's big island, Kilauea has been suggested to be the world’s most active volcano; having recorded 61 historical eruptions, not including the continuous lava-lake activity in Halema 'uma 'u Crater (Life Stages of Hawaiian Volcanoes). Kilauea is at it 's shield-forming stage referencing volcanology. During this stage the excretion systems within the volcanoes are the most efficient at transporting magma to the surface since over 95% of lava gets erupted. As well as the constant eruption, the magma chamber of the volcano fully develops to serve as a station for older, less dense magma. The magma chamber migrates upwards as a volcano grows and the Kilauea volcano magma chamber

The volcanoes are located where there is a divergence or convergence in the tectonic plates and bring their lava from the deepest of the terrestrial mantle. The materials and explosions of these ginates represent a constant risk in the places inhabited by the human being, nevertheless the people ususually live in these areas no matter the risk. On the other hand the volcanos can change the geology of an impressive form, or to cool the temperature of the earth, or to darken the sky. The scientific community increases its efforts to try to understand better what happens in volcanoes, however it is impossible to predict these conditions.

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.

Kilauea is one of the most active volcanoes on Earth, and it is the youngest. Kilauea stands just under 4,200 feet tall above sea level at its highest point.
