Mount Shasta is a large stratovolcano with four overlapping volcanic cones. Being a popular tourist destination, Mount Shasta attracts more than 26,000 visitors every year. While Mount Shasta is located to the north of the Lassen Volcanic National Park and the Lassen National Forest, both Mount Shasta and Lassen Peak are considered to be the southernmost active volcanoes in the Cascade Mountain Range. the hardened "volcanic plug" in the conduit. Most composite volcanoes have a crater at the summit which contains a The High Cascades arc axis in this segment of the arc is mainly a relatively narrow band of either monogenetic or short-lived shield volcanoes. Shasta is now ranked fifth out of a list of 18 volcanoes in the country that pose a "very high threat." Kilauea on the island of Hawaii is ranked first. A lock ( Popo (Mexico), Mt. The glaciers of Mount Shasta feed the Sacramento, McCloud and Shasta rivers. A dome grows largely by expansion Over the last 20,000 years, volcanic episodes have continued to build the mountain with lava flows and dacite cones.

It is also considered as the most voluminous stratovolcano that forms a part of the Cascade Volcanic Arc in the western portion of the North American continent and has a volume of 350 cubic kilometers. St. Helens between 1800 and 1857. Washington has five volcanoes that are listed as high or very high threat potential: Mount Baker, Glacier Peak, Mount Rainier, Mount St. Helens, and Mount Adams. Shasta is susceptible to lava and pyroclastic flows, lahars (mudflows), avalanches, and earthquakes. It is notable that Mount Shasta and Medicine Lake volcanoes, although volcanologically and petrologically quite different, span about the same range of ages and bracket the High Cascades axis on the west and east, respectively. Parcutin Volcano, Mexico, is a cinder cone Shasta has erupted periodically over the last 600,000 years and is considered an active volcano. instead of central vents and floods the surrounding countryside with lava ]. I have given these names from the tribes of Indians. Focal depths were very shallow near the surface fissures, but increased to 4-6 km along an inclined seismic zone dipping 35-45 E.

These volcanoes have broad bases and sides that get steeper and steeper as you get closer to the top. However, background seismicity at the Geysers is higher than at the other centers, and is influenced by fluid injection and withdrawal associated with intensive geothermal development. Mount Shasta has seven named glaciersWhitney, Bolam, Hotlum, Wintun, Watkins, Konwakiton, and Mud Creek. The High Cascades arc axis in this segment of the arc is mainly a relatively narrow band of either monogenetic or short-lived shield volcanoes.
