A Cascade Range volcano is one that is part of a series of mountains in western North America that includes an arc of volcanoes. The Cascade Range extends from British Columbia through Washington and Oregon to northern California.Know More
According to the United States Geological Survey, the Cascade Range volcanoes include the following:
Washington: Mount Adams, Mount Baker, Glacier Peak, Mount Rainier, and Mount St. Helens
Oregon: Mount Bailey, Belknap Shield Volcano, Crater Lake (Mount Mazama), Mount Hood, Mount Jefferson, Mount McLoughlin, Newberry Caldera, Mount Thielsen, Three Sisters; and California: Lassen Peak, Mount Shasta.
Mount Mazuma is the name given to the volcano that erupted about 8,000 years ago and subsequently collapsed to form Crater Lake.
A well-known Cascade Range volcano, Mount St. Helens famously erupted in May 1980 after an earthquake measuring 5.1 on the Richter scale shook its foundation. The earthquake triggered a collapse of the volcano's north face, and the subsequent avalanche of stone triggered the pressurized gases within the volcano to explode and send the falling debris into a wind that leveled 150 square miles of surrounding forest. The eruption lasted nine hours, although the initial explosions altered the volcano itself and the surrounding landscape instantaneously. The volcano continued to erupt periodically until 1986.Learn More
A volcano that has recently erupted and may erupt again soon is categorized as an active volcano. Dormant and extinct are also categories of volcanoes.Full Answer >
The lava from a volcano ranges in temperature from 570 to 2,120 degrees Fahrenheit. In comparison, water boils at 212 F, and a pizza oven is generally 500 to 600 F.Full Answer >
A volcano forms when magma rises through weakened areas of the crust from a magma reservoir many miles deep within the earth, pushing itself up through a vent. This vent acts as a release valve for pressure building up below, and when the new volcano erupts, thousands or millions of pounds of ash and molten rock slowly accumulate, forming a volcanic mountain.Full Answer >
An inactive volcano is called a dormant volcano or a sleeping volcano. Examples of dormant volcanoes include Mount Fuji and Mount Rainer.Full Answer >
