mount saint helens formed a massive buldge because the magma was blocked of frm the top of the volcano so it turned to the side and formed the big bulge the lava still couldn't get out so was forming the bulge to make more pressure on the skin that was blocking it from getting out in the end there was an earth quake measuring 5.1 on the Richter scale the north face of the volcano collapsed into a massive rock avalange the bulge was going down with it. nearly 230 square miles was blown down or buried beneath volcanic deposits.
What else can I help you with?
Is mount st helens intrusive?
No, Mount St. Helens is not an intrusive volcano. It is a stratovolcano, which is formed from explosive eruptions of viscous lava, ash, and other volcanic materials. An intrusive volcano forms when magma solidifies below the Earth's surface.
Is Mt St Helens a shield cinder cone or composite volcano?
No. In terms of the size of the structure itself, the largest volcano on Earth is Mauna Loa, which makes up the majority of the volume of the isaldn of Hawaii (the big island). The largest volcano known to science is Olympus Mons on Mars. The tallest volcano on Earth in terms of elevation is Ojos de Salado on the Chile-Argentina border at 22,615 feet. By comparison Mount St Helens is at 8,365 feet (9,677 before the 1980 eruption). Mount St Helens did not produce the largest eruption either. The largest volcanic eruption in recorded history was the 1815 eruption of Mount Tambora in Indonesia, which was on the order of 100-200 times larger than the 1980 eruption of Mount St Helens.
What is the name of the biggest volcano on the Earth?
I know this one. I will come back later to tell you the answer. But the only thing I can tell you about the biggest volcano on Earth is that it's bigger than Mount. Everest! And another thing - it's in Hawaii.
What rock type is mount st Helens?
Mount St. Helens is predominantly composed of andesite, which is an intermediate volcanic rock that forms from the partial melting of the Earth's crust. This type of rock gives Mount St. Helens its characteristic gray color and is related to the volcanic activity in the area.
What is the latitude and longitude of composite volcano?
A composite volcano is a type of volcano that can be present anywhere on Earth. If you are looking for the latitude and longitude of a certain composite volcano, please state the name of a specific composite volcano in the question.
Is mount Olympus the biggest volcano in the solar system?
No, the biggest volcano in the solar system is Olympus Mons on Mars (Mount Olympus is on Earth).
Is mount st helens intrusive?
No, Mount St. Helens is not an intrusive volcano. It is a stratovolcano, which is formed from explosive eruptions of viscous lava, ash, and other volcanic materials. An intrusive volcano forms when magma solidifies below the Earth's surface.
Is mount st Helens the youngest volcano on earth?
No, not by any definition. If you define the "youngest volcano" by "most recently erupted", then that honor goes to Kilauea, which has been erupting non-stop since 1983. Mount St. Helens last "erupted" in early 2008 when steam escaped from a fracture in the lava dome.
How was the earth's surface built up as result of the eruption of mount st helens?
the two of earths plat collided and formed upwards and made a volcano!

Is Mauna Loa the biggest volcano on earth?
yes. mauna loa is the biggest volcano.
How is the formation of Mount St. Helens volcano different than a hot-spot volcano?
Mount St. Helens is a stratovolcano formed by the subduction of tectonic plates, where the Pacific plate is being forced beneath the North American plate. Hot-spot volcanoes, like the Hawaiian Islands, are formed by magma that rises from a fixed mantle plume hotspot under the Earth's crust.
How was mount st Helen erupted?
Mt. St. Helens erupted by the pressure to make a volcano explode. Lava originates deep below the Earth's surface where it is still extremely hot, with magma at the bottom of the lava. a 5.1 earthquake triggered mt st helens to erupt

What is a volcano?
A volcano is a mount (or mountain) that has magma in it. A volcano also is like an earthquake releasing pressure from the inner core of the earth. If there is a lot of pressure to be released this will cause the eruption to be bigger and more destructive, like the volcano Mount Tambora that erupted in 1815.
What is the latitude and longitude of composite volcano?
A composite volcano is a type of volcano that can be present anywhere on Earth. If you are looking for the latitude and longitude of a certain composite volcano, please state the name of a specific composite volcano in the question.
