What is the volume of magma Mt St Helens could hold?
Mount St. Helens could possibly hold up to 0.3 cubic kilometers of magma in its magma chamber. However, the exact volume can fluctuate based on various factors such as temperature, pressure, and composition of the magma.
What types of materials are volcanoes like Mount St. Helens made of?
Mount St Helens is made up of andesitic and rhyolitic pyroclastic materials.
What attraction did mt st helens have on the tourists?
Who knows? Probably the place where it blew up.
Why a bulge formed on the north side of mt. St. Helens just before it erupted?
A "bulge" developed on the north side of Mount St. Helens as magma pushed up within the peak.
What is the value of a salt and pepper shaker set made from the ash of Mt St Helen?
Different artifacts made from the ash of the volcano Mt. Saint Helens can be worth up to $150. Mt. Saint Helens ash salt and pepper shakers are currently selling on Etsy for as little as $8.00.

What caused mt st helens to erupte in 1980?
The plates of earth rest on liquid lava (the mantel). As they move pressure builds up under the volcano and when its too much it explodes.
What type of eruption was the 1980 eruption of mt st Helens?
The 1980 eruption of Mount St. Helens was a explosive eruption caused by a lateral blast. It was triggered by a massive collapse of the volcano's north flank, releasing pressure built up within the volcano.
What caused the eruption of Mt St Helen?
The eruption of Mount St. Helens in 1980 was caused by a combination of tectonic plates colliding, resulting in the build-up of pressure and magma beneath the surface. The eruption was triggered by an earthquake that caused the north face of the mountain to collapse, releasing the pent-up pressure and explosive eruption of ash, gas, and molten rock.
