Mount St. Helens is known for its explosive eruptions. In 1980, it erupted violently and produced a massive explosive eruption that caused significant devastation to the surrounding area. Subsequent eruptions have also been explosive in nature.
Mount St. Helens has experienced varying eruption frequencies since its most notable eruption in 1980. Following that event, the volcano entered a period of intermittent activity, with eruptions occurring approximately every few years until 2008. Since then, it has been relatively quiet, but it remains an active volcano with the potential for future eruptions. Monitoring continues to assess any signs of volcanic activity.
The land around Mount St. Helens has been used for tourism, camping, and logging.
Mount St Helens is a Composite Cone Volcano (meaning it is infrequent yet violent) and Kilauea is a Shield Volcano (meaning it is not violent). A shield volcano is widely spread between two continental crust though Kilauea is on a hot spot. Meaning it is in the middle of a plate. Composite Cone Volcanos are located between oceanic plates and continental crusts.

Two major volcanic eruptions that have occurred in the last 100 years are the eruption of Mount Pinatubo in the Philippines in 1991, and the eruption of Eyjafjallajökull in Iceland in 2010. Both eruptions had significant impacts on their surrounding regions and beyond.

Mt. St. Helens does not have eruptions on a yearly basis. It is an active volcano, so the frequency and size of eruptions can vary. Since its catastrophic eruption in 1980, there have been smaller eruptions in subsequent years, but there is no fixed average number of eruptions per year.

Mount St. Helens is a living laboratory of volcanic study and the most studied volcano in the world. The USGS has been studying the volcano for over 30 years and lessons they have learned have saved many lives across the globe with their volcanic prediction science.
