The 1980 eruption of Mount St. Helens is surpased by a volcano that was formed in 1912 located where?
1980 eruption of Mount St. Helens On May 18, 1980, a major volcanic eruption occurred at Mount St. Helens, a volcano located in Skamania County, in the state of Washington, United States. The eruption (a VEI 5 event) was the only significant volcanic eruption to occur in the contiguous 48 U.S. states since the 1915 eruption of Lassen Peak in California. However, it has often been declared as the most disastrous volcanic eruption in United States history. The eruption was preceded by a two-month series of earthquakes and steam-venting episodes, caused by an injection of magma at shallow depth below the volcano that created a large bulge and a fracture system on the mountain's north slope.
Mount Egon Mount Egon (Gunung Egon, sometimes also called Gunung Namang) is a stratovolcano located in the southeastern part of the island of Flores, Indonesia in the area of Maumere bay. A landslide during the eruption on 29 January 2004 forced 6,000 people to evacuate the area. Activity of Gunung Egon on 15 April 2008 forced thousands of people to evacuate. Quakes and fumes from the volcano have been occurring since November 2010, designating Egon as one of 11 volcanoes in Indonesia on the highest level alert.
