During which natural disaster were evacuation efforts most successful?
The eruption at Mount Pinatuba.
What magma composition does Mt Hekla have?
Mt. Hekla in Iceland has a composition of intermediate to felsic magma, which is rich in silica, giving it a higher viscosity compared to basaltic magma. This type of magma can lead to explosive eruptions.
How does magma composition and the resulting eruption affect the form of a volcano?
If the composition of the magma is high in silica, the eruption will be explosive. The Eruption of Mt. St. Helens was an explosive eruption. If the composition of the magma is low in silica, it will produce a quiet eruption. The eruption(s) of Mt. Kilauea are quiet eruptions.
What type of lava forms mt hood?
Mt. Hood is primarily composed of andesitic lava, which is intermediate in composition between basaltic and rhyolitic lavas. Andesitic lava is characterized by its viscosity and tendency to form lava domes, lava flows, and pyroclastic flows.
Does Mt Makushin have sticky magma?
It is possible that Mt. Makushin, a stratovolcano in Alaska, may have sticky magma due to its composition and eruptive history. However, detailed studies would be needed to determine the specific properties of its magma.
Where is pinatuba?
Philippines
Where is Mount Pinatuba?
Philippines
What type of magma does Mt Etna have?
The composition of Mt. Etna is basaltic.
What year did pinatuba erupt?
it erupted in the year 1991
What was the first time mount pinatuba eruped?
1400 century
During which natural disaster were evacuation efforts most successful?
The eruption at Mount Pinatuba.
How can the composition of magma affect the way volcano erupts?
If the composition of the magma is high in silica, the eruption will be explosive. The Eruption of Mt. St. Helens was an explosive eruption. If the composition of the magma is low in silica, it will produce a quiet eruption. The eruption(s) of Mt. Kilauea are quiet eruptions.
What magma composition of mt Saint Helen?
it was 2000 digrees faren height
What magma composition does Mt Hekla have?
Mt. Hekla in Iceland has a composition of intermediate to felsic magma, which is rich in silica, giving it a higher viscosity compared to basaltic magma. This type of magma can lead to explosive eruptions.
What is mt vesuvius composition?
Mount Vesuvius' magma is comprised mostly of pumice stone. It is low density molten rock that erupts at a high temperature.
How does magma composition and the resulting eruption affect the form of a volcano?
If the composition of the magma is high in silica, the eruption will be explosive. The Eruption of Mt. St. Helens was an explosive eruption. If the composition of the magma is low in silica, it will produce a quiet eruption. The eruption(s) of Mt. Kilauea are quiet eruptions.
What made mt st Helens so explosive?
Mount Saint Helens' magma/lava composition is different to many volcanoes and is about 64%silica and 4% water.
