Answer 1

Answer:

E. debris flow

Explanation:

• On May 1980 a major volcanic eruption occurred on Mount St. Helen's, located in Washington. Hot mix of lava and older rocks overtook the shape of an avalanche and the debris-laden mass of soil fragmented ricks and mudslides overtook the river systems and created liquefaction and high fluid pressure.
