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.
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 .
Mount Scott first erupted about 420,000 years ago and is one of the oldest volcanoes in the Mount Mazama complex. [8] [9] It erupted mainly andesitic lavas before becoming extinct in the late Pleistocene. [10] Since it was relatively far away from the main flanks of Mount Mazama, it survived the mountain's massive explosion that occurred around ...

The Cascade Arc formed during the Oligocene epoch, and by the late Miocene epoch there was a low but broad gap between the Washington segment of the arc and Cascade volcanoes in Oregon. Activity picked up during the Quaternary period in Washington, as andesitic stratovolcanoes and small, olivine basalt cinder cones and shield volcanoes erupted. [8]
