Answer: Mount St. Helens is a volcano located in Washington State.
Step-by-step explanation:
Mount St. Helens is a volcano located in Skamania County, Washington state, in the Pacific Northwest region of the United States. It is part of the Cascade Range of mountains, which runs from Northern California to British Columbia, Canada.
Mount St. Helens is most famous for its eruption on May 18, 1980, which was one of the most destructive volcanic eruptions in U.S. history. The eruption, triggered by a 5.1 magnitude earthquake, caused the collapse of the volcano's north flank, leading to the largest landslide in recorded history. This landslide, in turn, triggered a massive blast of hot gases, ash, and rock debris that traveled at high speeds down the volcano's slopes and devastated the surrounding area.
The eruption killed 57 people and caused extensive damage to homes, infrastructure, and the environment. Since then, the area around Mount St. Helens has become a laboratory for the study of volcanic processes and their impact on the ecosystem. Today, the mountain is still an active volcano, although it has been relatively quiet since the 1980 eruption.
