What kind of volcano is mt st Helen's?
Mount St. Helens is a stratovolcano, also known as a composite volcano. Stratovolcanoes are characterized by their steep, symmetrical cones built up by layers of hardened lava, ash, and rocks. They are known for explosive eruptions due to the high viscosity of their lava.
The type of volcano formed from violent eruptions of a volcano?
A stratovolcano, also known as a composite volcano, is formed from violent eruptions characterized by explosive activity that ejects a mixture of lava, ash, and volcanic rocks. These eruptions are typically associated with high levels of gas pressure within the magma chamber, leading to explosive events.
What type of eruption does MtFuji produce?
It is a composite volcano, so the kind of eruptions it has is explosive.
Is Mt Rainier an explosive or a quiet eruption?
Mount Rainier is known for having the potential for explosive eruptions due to its large volume of magma that can lead to significant ash and pyroclastic flow hazards. However, it is also possible for the volcano to have more quiet eruptions that primarily involve the effusion of lava flows.
What are some volcanos?
Some well-known volcanoes include Mount St. Helens in the United States, Mount Vesuvius in Italy, and Mount Fuji in Japan. These volcanoes have had significant eruptions throughout history.

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.
Why do the volcanoes in Japan have explosive eruptions?
Volcanoes in Japan have explosive eruptions because there is a a magma chamber that has not completely move along the mantle yet so when it erupts it has explosive eruptions.

Why was Mount Saint Helens eruption so famous?
use it
How many eruptions on average does mt saint helens have per year?
Mt. St. Helens does not have eruptions on a yearly basis. It is an active volcano, so the frequency and size of eruptions can vary. Since its catastrophic eruption in 1980, there have been smaller eruptions in subsequent years, but there is no fixed average number of eruptions per year.
Is Mount saint helens a volcano?
yes, it is and so called deadly.
What are some volcanos?
Some well-known volcanoes include Mount St. Helens in the United States, Mount Vesuvius in Italy, and Mount Fuji in Japan. These volcanoes have had significant eruptions throughout history.
Why is Mt St Helens eruption so well known?
Because I think it was one of the biggest eruptions.
Is mount st. Helen's active?
Mount St. Helens is geologically young compared with the other major Cascade volcanoes. It formed only within the past 40,000 years, and the pre-1980 summit cone began rising about 2,200 years ago. The volcano is considered the most active in the Cascades within the Holocene epoch (the last 10,000 or so years).
