1 Mount Teide is currently a dormant volcano, but many scientists believe it will erupt again in the near future. 2  In the mid seventeenth century a group of Englishmen were the first Europeans to reach the summit of Mount Teide. The most recent eruption of Mount Teide happened in 1909. 2  It also erupted in 1798, 1706, 1705 and 1704. 3  On his voyage of discovery Christopher Columbus apparently saw the 1492 eruption of Mount Teide when he was sailing past Tenerife.
Mount Mazama is a stratovolcano in the Oregon segment of the Cascade Volcanic Arc and the Cascade Range located in the United States. The volcano 's collapsed caldera holds Crater Lake, and the entire mountain is located within Crater Lake National Park.When it last erupted, the eruption was 42 times greater than the eruption of Mount St. Helens in 1980. Mazama's summit was destroyed by a volcanic eruption that occurred around 5677 (Â± 150) BC.The eruption reduced Mazama's approximate 12,000-foot (3,700 m) height by about 1 mile (1,600 m). Much of the volcano fell into the volcano's partially emptied neck and magma chamber.hen it last erupted, the eruption was 42 times greater than the eruption of Mount St. Helens in 1980.
