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.
‘Most dangerous volcano in the Cascades’ The lowlands around the Puyallup River, down to Commencement Bay, could be affected by a lahar, said Steve Malone, a retired seismologist with the ...
Mount Rainier [a] (/ r eɪ ˈ n ɪər / ray-NEER), also known as Tahoma, is a large active stratovolcano in the Cascade Range of the Pacific Northwest in the United States. The mountain is located in Mount Rainier National Park about 59 miles (95 km) south-southeast of Seattle. [9]
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 .
USGS Cascades Volcano Observatory geophysicist Rebecca Kramer works on station PR05, part of the Mount Rainier lahar detection network. The system has been upgraded and expanded since it was first ...
[32] [33] Seismic activity is monitored by the USGS Cascades Volcano Observatory in Vancouver, Washington, which issues weekly updates (and daily updates if significant eruptive activity is occurring at a Cascades volcano). [34] The most recent evidence of volcanic activity at Mount Hood consists of fumaroles near Crater Rock and hot springs on ...
Mackenzie, Muschalik & Broesche (2021) provided comments on the 2018 report in three separately authored sections. [4] Broesche believes that Yellowstone should be ranked higher due to the size of the volcano and the popularity of Yellowstone National Park, and Muschalik considers Mount Rainier to be just as dangerous as Kilauea due to its proximity to large population centers in Washington.
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. Lassen Peak (south of Mount Shasta) — southernmost volcano in the Cascades and the most easily climbed peak in the Cascades. It erupted from 1914 to 1921 ...
