Mount Mazama is located in Oregon, with a height of approximately 11,000 ft. This monstrous volcano was not only one, but 5 cones combined. “Mount Mazama's first eruption was somewhere around 420,000 years ago,” says UMASS (the University of Massachusetts). As hundreds of thousands of years passed, Mazama’s eruptions became more violent and destructive. These eruptions usually included thick lava and slow flows. USGS informs us. “These eruptions, however, were nothing compared to Mount Mazama’s major eruption years after.” …show more content…
USGS Publications Warehouse proves. “Composite volcanoes are built by multiple eruptions, sometimes recurring over hundreds of thousands of years, sometimes over a few hundred. Andesite magma, the most common but not the only magma type, tends to form composite cones.” Says UCSB. A Shield volcano has a circular bowl-shaped top and is rarely taller than 1,000 feet high above the ground. Why are they named shield volcanoes? Because the mountains typically resemble a warrior's shield lying on the ground. Most shield volcanoes have craters, which you also can see on Mount Mazama. When a lot of Magma is released from the volcano's magma chamber, it may collapse. UCSB informs us again. Which also happened to Mount
