Mount St. Helens, located in southwestern Washington state in the Cascade mountain range, erupted on May 18, 1980. Sixty-one people died as a result of the eruption. This was the first known volcanic eruption in the 48 contiguous United States (excluding Alaska and Hawaii) to claim a human life. Mount St. Helens is classified as a composite volcano (a steep-sided, often symmetrical cone constructed of alternating layers of lava flows, ash, and other volcanic debris). Composite volcanoes tend to erupt explosively.

Why did the eruption of Mount St Helens result in the formation of a key bed?
The eruption of Mount St. Helens resulted in the formation of a key bed because the volcanic ash and debris were deposited over a wide area in a relatively short period of time. This layer of ash can be easily identified and dated, making it a useful marker bed for correlating rock layers in different locations.

What is happening at this current time at Mount St Helens?
Mount St. Helens is currently in a state of volcanic quiescence, with no signs of imminent eruption. Monitoring stations are actively tracking the volcano's activity for any potential changes to provide early warning if it becomes restless again. The U.S. Geological Survey continues to keep a close eye on Mount St. Helens and surrounding areas for any signs of volcanic activity.
What made Mt Saint Helen's to erupt?
The eruption of Mount St. Helens in 1980 was triggered by a combination of magma rising towards the surface, increasing pressure in the volcano, and a sudden release of built-up gases. This led to a flank collapse on the north side of the volcano, resulting in a massive eruption that devastated the surrounding area.
