Much of Mount Rainier is composed of andesitelava flows. Lava flows may accompany explosive eruptive activity, but they occur more often after explosive activity declines. The term "andesite" refers to the chemical composition of the rock. Andesite lavas tend to be moderately viscous and rather slow moving: on gentle slopes, they may move much more slowly than a person can walk.
What else can I help you with?
What type of lava forms mt rainer?
Mount Rainier is composed primarily of andesite lava, which is an intermediate type of lava that has a higher silica content compared to basaltic lava. This type of lava is more viscous, leading to explosive eruptions and the formation of volcanic cones like Mount Rainier.
Did mt rainier erupt in 2010 yet?
No. Mount Ranier has not erupted since 1894.
What type of magma is in mt rainier?
Mt. Ranier is a hot ash volcano like Mt. Saint Helens. So when it erupts, hot ash explodes out like a mushroom cloud and then disperses over a wide area. Lahars cause mudslides and water and debris flow down the mountain. Lava does not pour out though, because it is a hot ash volvano, both types of mountains have magma underneath.
When is Mt Rainier expected to erupt?
Mt. Rainier is an active volcano but is currently not expected to erupt imminently. Volcanic activity is monitored regularly by the United States Geological Survey to provide early warning if any significant changes occur.
Is Mt Rainier in Oregon?
No, Mt. Rainier is not in Oregon. It is actually located in the state of Washington, in the Cascade Range.
What type of lava forms mt rainer?

Did mt rainier erupt in 2010 yet?
No. Mount Ranier has not erupted since 1894.
What type of lava and characteriscics in mt rainier?
Mt. Rainier has granitic and basaltic lava types. It is a stratovolcano or composite volcano. The volcano has 26 major glaciers and 36 snowfields on it. Also, it has a glacier cave network, the world's largest, made from the heat from two volcanic craters. Arelativelysmall crater lake sit on Mt. Rainier. The lake is the highest elevation lake in North America. This volcano has dangerous lahars, because of its many glaciers and river paths. The convergent boundary of the North American and Juan de Fuca plate caused Mt. Rainier to form.
What type of mountain is mt rainier?
A volcanic mountain.
How fast is the lava or ash flowing from mt rainier during an eruption?
2 inches per hour
How did mt vesuvius erupt?
An underground earthquake sent the lava plume high in the air.
What type of lava is mt redoubt?
what type of lava does mt.redoubt have
What kind of lava is in Mt Vesuvius?
the type of lava from mt vesuvius is felsic lava in a pyroclstic explosion.
What are 3 cascade volcanoes that can erupt at anytime?
Mt. Hood, Mt. Rainier, Mt. Saint Helens, Mt. Baker Really, any major mountains in Oregon as well. The first three I mentioned are the most probable.
Are there tapeworms at Mt Rainier national park?
NO there are no tapeworms at mt. rainier.
What type of magma is in mt rainier?
Mt. Ranier is a hot ash volcano like Mt. Saint Helens. So when it erupts, hot ash explodes out like a mushroom cloud and then disperses over a wide area. Lahars cause mudslides and water and debris flow down the mountain. Lava does not pour out though, because it is a hot ash volvano, both types of mountains have magma underneath.
What caused Mt Etna volcano to erupt in 1669?
it was simply just tectonic plates that pushed the lava through.
