The Cascade Volcanoes (also known as the Cascade Volcanic Arc or the Cascade Arc) are a number of volcanoes in a volcanic arc in western North America, extending from southwestern British Columbia through Washington and Oregon to Northern California, a distance of well over 700 miles (1,100 km).

The U.S. Geological Survey's Cascades Volcano Observatory strives to serve the national interest by helping people to live knowledgeably and safely with volcanoes in Washington, Oregon, and Idaho.

This is a list of Cascade volcanoes, i.e. volcanoes formed as a result of subduction along the Cascadia subduction zone in the Pacific Northwest of North America. The volcanoes are listed from north to south, by province or state: British Columbia, Washington, Oregon, and California.

The familiar snow-clad peaks of the Cascade Range are part of a 1,300 km (800 mi) chain of volcanoes, which extends from northern California to southern British Columbia. The volcanoes are the result of the slow slide of dense oceanic crust as it sinks beneath North America (subduction), which releases water and melts overlying rock.

2025年1月28日 · Researchers used seismic waves to identify magma chambers beneath the surface of six volcanoes of various sizes and dormancy within the Cascade Range, which includes half of the U.S. volcanoes designated by the …

2024年5月2日 · This month we'll take a tour of the Cascade Range volcanoes, all located along the western edge of North America. Some will be very familiar but others are hidden gems (and dangers) of the Pacific Northwest.

The Cascade Volcanic Arc (also known as the Cascades or the Cascade Range) is a major range of volcanoes in southwestern British Columbia, Washington, Oregon, and northern California. The arc is central to the Cascade Range, a mountain range in the Pacific Northwest. It includes about 20 major volcanoes, among over 4,000 separate volcanic vents ...

2023年12月6日 · Hot lava meets snow and ice at ice-clad Cascade volcanoes. An estimated two cubic miles of glacier ice and perennial snow cover the Cascade Range volcanoes today, and more than half of that amount is on Mount Rainier.

The volcanoes in this category are found in California, Oregon, Washington, and British Columbia, and in two different mountain ranges, the Cascade Range and the Coast Mountains. The Cascade volcanoes are part of the Pacific Ring of Fire that includes over 160 active volcanoes.
