The Cascade volcanoes have had more than 100 eruptions over the past few thousand years, many of them explosive eruptions. [21] However, certain Cascade volcanoes can be dormant for hundreds or thousands of years between eruptions, and therefore the great risk caused by volcanic activity in the regions is not always readily apparent.
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 volcano has a volume of 6.0 cubic miles (25 km 3). [8] Mount Bachelor stands 3 miles (4.8 km) southeast of the Tumalo Mountain volcano and 18 miles (29 km) to the southwest of the city of Bend, [2] in the Deschutes National Forest. [9] Weather varies greatly in the area due to the rain shadow caused by the Cascade Range. Air from the ...
The Cascade Volcanic Arc is a chain of volcanoes stretching from southern British Columbia down to northern California. Within the arc there is a variety of stratovolcanoes like Mount Rainier and broad shield volcanoes like Medicine Lake. But calderas are very rare in the Cascades, with very few forming over the 39 million [1] year lifespan of ...
Medicine Lake Volcano — a shield volcano in northern California which is the largest volcano by volume in the Cascades. Mount Shasta (northern California) — second highest peak in the Cascades. Can be seen in the Sacramento Valley as far as 140 mi (230 km) away, as it is a dominating feature of the region.
The Juan de Fuca tectonic plate is being subducted under the North American Plate, leading to volcanic activity in the Cascades like at West Crater. In southern Washington state, the Cascade Range, which sits south of the dacitic Garibaldi Volcanic Belt, spans 600 miles (970 km) from British Columbia in Canada to Lassen Peak in northern California in the United States.

The Cascade volcanoes are part of the Pacific Ring of Fire that includes over 160 active volcanoes. Articles listed under this category should be cross-listed under the correct geographical categories too. For mountain range categories, the appropriate choices are Category:Cascade Range or Category:Pacific Ranges.
