Mount St. Helens is a stratovolcano located in
Washington,
USA. Volcanic activity beginning in March 1980 saw magma accumulating underneath the mountain's north flank. On
May 18, 1980, an earthquake triggered the collapse of the flank and a lateral eruption which killed 57 people. It was the deadliest volcanic event in US history.
Bezymianny is a stratovolcano located on the
Kamchatka peninsula in
Russia. On March 30, 1956, it erupted laterally after a flank collapse similar to that experienced by Mount St. Helens. No fatalities resulted from this eruption due to the remote location of the volcano. Subsequent lava dome growth has since filled the 1956
caldera with a new cone.
Mount Pelée is a volcano located on
Martinique, in the
Caribbean. It underwent a lateral eruption on
May 8, 1902, killing 28,000 people in the deadliest volcanic event of the 20th century.
San Francisco Peaks in Arizona are the remnants of a single taller volcano that may have had a lateral eruption around 200,000 years ago.
Nevado de Toluca is a stratovolcano to the west of Toluca, Mexico. About 25,000 years ago, Nevado de Toluca experienced a large, lateral blast to the east which reduced the elevation by about 3000ft. Like Mount Saint Helens, Nevado de Toluca also experienced dome building in the caldera subsequent to the blast.
Mount Meru (Tanzania) is a stratovolcano in
Tanzania near Mount Kilimanjaro. About 7800 years ago, Mount Meru experienced a lateral blast to the east. Subsequent eruptions have occurred in the caldera since then, most recently in 1910. == References ==
