The Cascade Volcanoes are part of the Pacific Ring of Fire, the ring of volcanoes and associated mountains around the Pacific Ocean. The Cascade Volcanoes have erupted several times in recorded history. Two most recent were Lassen Peak in 1914 to 1921 and a major eruption of Mount St. Helens in 1980.
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 Pacific Northwest volcanoes continue to be a geologically active area. The most geologically recent volcanic eruptions include: Level Mountain, Canada's most voluminous and most persistent eruptive center, might have erupted in the Holocene. Nazko Cone, the youngest volcano in the Anahim Volcanic Belt, erupted 7200 BP.
The east side of Mount Baker in 2001. Sherman Crater is the deep depression south of the summit. Mount Baker (Nooksack: Kweq' Smánit; Lushootseed: təqʷubəʔ), [9] also known as Koma Kulshan or simply Kulshan, is a 10,781 ft (3,286 m) active [10] glacier-covered andesitic stratovolcano [5] in the Cascade Volcanic Arc and the North Cascades of Washington State in the United States.
The Northern Cordilleran Volcanic Province is part of an area of intensive earthquake and volcanic activity around the Pacific Ocean called the Pacific Ring of Fire. However, the Northern Cordilleran Volcanic Province is commonly interpreted to be part of a gap in the Pacific Ring of Fire between the Cascade Volcanic Arc further south and the ...
Today, the Cascadia Subduction Zone remains eerily quiet. In other subduction zones, scientists often observe small earthquakes frequently, which makes the area easier to map, according to ...
Many geological features in Western United States have a Northeastern orientation, the North American craton motion has the same orientation as well. [1] For example: the Trans-Challis fault zone, Idaho; the Snake River in Oregon; the Garlock Fault, California; the Colorado River in Utah; the Colorado Mineral Belt; Crater Flat-Reveille Range-Lunar Crater lineament, the Northwestern Nevada ...
It is monitored by the Pacific Northwest Seismic Network and the Cascades Volcano Observatory via a seismic station on the southwest flank of the mountain. [47] During the month of September 2024, the U.S. Geological Survey Cascades Volcano Observatory recorded six earthquakes ranging in magnitudes 0.9 to 2.0. With a normal rate of one ...
