soufrière hills eruption history

The explosions were spaced about 20 minutes apart and sent ash and steam about 40 meters high. Size of eruption: Large- 4.5 million m cubed of rocks and gas was released. The capital city was called Plymouth before it was buried in debris after the eruption. Soufrière, French La Soufrière, active volcano on the island of Saint Vincent, in the country of Saint Vincent and the Grenadines, which lies within the Lesser Antilles in the Caribbean Sea.The volcano rises to peaks of 3,864 feet (1,178 metres) and 4,048 feet (1,234 metres) north of the crater. It is a motto that still guides the work of the U.S. Geological Survey's Hawaiian, Cascades, and Alaska Volcano Observatories. The initial eruption was apparently a small phreatic (steam) event which produced minor ash that was distributed about the island by the wind. The next active volcano to the south is the infamous Mont Pelee on the island of Martinique.

Several large explosions were registered, with the largest at approximately 11:38 pm.

The summit area consists primarily of a series of lava domes emplaced along an ESE-trending zone. History And Timeline Created by: Lottie_Anderson; Created on: 18-03-13 16:54; Volcanic Eruption- Soufriere Hills, 1997 . Its first historic eruption started in 1995 and is still ongoing. Volcano in the Soufrière Hills of Montserrat, erupting on January 23, 2010. Volcanic Eruption- Soufriere Hills, 1997. On July 22, light ashfall occurred in the capital of Plymouth, located about four kilometers west of the summit, and in villages to the southwest of the summit.The activity, though minor so far, is being taken quite seriously because of the risk to the people and because other similar volcanoes in the region have had large, destructive eruptions in the past. These involved juvenile material originating in the collapse of the eruption column. It is made up of andesitic lava, in the form of eroded lava domes and sequences of volcaniclastic beds (formed from pyroclastic fan deposits around the lava domes and debris avalanche deposits). English's Crater, a 1-km-wide crater breached widely to the east, was formed during an eruption about 4000 years ago in which the summit collapsed, producing a large submarine debris avalanche. Eruption list: 1995-2011, 2012 Background: Montserrat's Soufrière Hills volcano is a typical subduction volcano. The volcano is flanked by Pleistocene complexes to the north and south. The volcano is flanked by Pleistocene complexes to the north and south. The complex, dominantly andesitic Soufrière Hills volcano occupies the southern half of the island of Montserrat. Its existence is due to the subduction of the Atlantic under the Caribbean plate. The motto of his new observatory was "Ne plus haustae aut obrutae urbes" or "No more shall the cities be destroyed." Soufriere means "sulfur" in French, hence the inordinate number of volcanoes that bear the same name.The southernmost active volcano in the chain is named Kick 'em Jenny. This is the first eruption of the volcano in historic time.Five scientists and technicians from the U.S. Geological Survey's Volcano Crisis Assistance Team, headquartered at the Cascades Volcano Observatory in Vancouver, Washington, are responding to this eruption with additional seismic equipment and expertise. It is north of Guadeloupe Island, home of Soufriere Volcano, which has had nine eruptions since 1660, with the most recent in 1976.Farther south is Micotrin Volcano on the Island of Dominica, which last erupted in 1880.
