What plate tectonic is Mt St. Helens located on?
Mount St. Helens is located on the convergent boundary between the Juan de Fuca Plate and the North American Plate. The subduction of the Juan de Fuca Plate beneath the North American Plate is responsible for the volcanic activity in the region. This tectonic activity leads to the formation of stratovolcanoes like Mount St. Helens, which famously erupted in 1980.
What type of eruptions does mount st Helens do?
Like most stratovolcanoes, Mount St Helens alternates between explosive and effusive eruptions.
What types of materials are volcanoes like Mount St. Helens made of?
Mount St Helens is made up of andesitic and rhyolitic pyroclastic materials.
What volcano was most recently active in the continental US?
AnswerI would have to say Mt St. Helens in Washington State. Mount St. Helens erupted on May 18, 1980 killing 57 people and destroying 250 homes, 15 miles of railways, 185 miles of highway and many miles of forest. It uprooted trees like matchsticks and spewed a combination of mud, ash and debris 63,000 feet in the air. Yakima, a city across the Cascade Mountains from Mt. St. Helens was covered with six feet of ash. Drivers of cars had to put nylons over their tailpipes to keep them from clogging. Mt. St. Helens continues to be active today but this was its most spectacular eruption.103
What other volcanoes are near mt st helens?
Near Mount St. Helens, several notable volcanoes are part of the Cascade Range, including Mount Adams to the east and Mount Rainier to the north. Additionally, Mount Hood lies to the south in Oregon. These volcanoes, like Mount St. Helens, are part of the Pacific Ring of Fire and have histories of volcanic activity, contributing to the region's dynamic geological landscape.

How many times has composite volcano erupted?
Composite volcanoes, also known as stratovolcanoes, have erupted numerous times throughout geological history, though the frequency varies by specific volcano. For example, Mount St. Helens has erupted over 20 times since its major eruption in 1980, while others like Mount Fuji have experienced significant eruptions approximately every few decades to centuries. Overall, the eruption history of composite volcanoes can span thousands of years, with many having multiple eruptions recorded.
