Mt Saint Helens was caused to erupt because when two plates collided together-the continential (named:North American Plate) was forced over the oceanic crust (named: Juan De Fuca) causing the top of the moutain to blow over the side of the mountian. The oceanic crust goes deeper and deeper into the continential crust that when soon it reaches the lithosphere (the mantle) causing it to melt into lava. Then the hot pressure shoots up the magma chamber and shoots out the top causing mt saint helens. Mt saint helens erupted on May 18, 2000 in Skamania County in Washington. This explosion cause tons of ash, hot rock, and gas. Over 57 people were sadly killed in this eruption. The mountain range that mt saint helens was located on was the Cascade Range which was firts descovered by Thomas J. Dryer.
