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.
Tequila Volcano Standing at a height of 2,920 meters (9,580 feet) above sea level, "The Tequila Volcano", or "Volcán de Tequila is a Stratovolcano located near Tequila, Jalisco, in Mexico." Stratovolcanoes, also referred to as Composite Volcanoes, are the "iconically" conical-shaped volcanoes, found most commonly along subduction zones. Stratovolcanoes are composed of steeply dipping layers of lava, hardened ash, and other material that erupted from the main vent such as tephra and pumice. Commonly higher than 2500 meters above sea-level, Stratovolcanoes have gentle lower slopes which gradually become steeper the higher you get with a relatively small summit crater. Due to their eruptions, Stratovolcanoes have several distinct variations giving some a specific feature such as calderas and amphitheaters.
