when was the last time the tungurahua volcano erupted
Tungurahua Tungurahua, (/tʊŋɡʊˈrɑːwə/; from Quichua tunguri (throat), rahua (fire): "Throat of Fire"[5] or from Panzaleo) is an active stratovolcano located in the Cordillera Oriental of Ecuador. The volcano gives its name to the province of Tungurahua. Volcanic activity restarted on August 19, 1999,[6] and is ongoing as of 2013[update], with several major eruptions since then, the last starting on 1 February 2014.[7][8]
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. The eruption (a VEI 5 event) was the most significant volcanic eruption to occur in the contiguous 48 U.S. states since the 1915 eruption of Lassen Peak in California.[1] It has often been declared as the most disastrous volcanic eruption in U.S. 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.
