MONTSERRAT-VOLCANO-SOUFRIERE-NASA
A picture released by the Nasa Earth Observatory on Februray 17, 2010 of a Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA?s Aqua satellite captured true-color image on February 11, 2010, the same afternoon that the dome collapsed. An east-west volcanic plume completely obscures the island of Montserrat, casting a shadow toward the northeast. Two smaller, fainter plumes also extend from the island, one to the north and the other to the south. The northern plume lies in the shadow of the east-west plume and consequently must occur at a lower altitude. At 12:35 p.m. local time on February 11, 2010, Soufri?re Hills Volcano on the Caribbean island of Montserrat experienced a partial dome collapse. Lasting nearly an hour, the event sent a plume 50,000 feet (15,240 meters) skyward, and sent pyroclastic flows?avalanches of hot gas and debris?some 300 to 400 meters (980 to 1,200 feet) out to sea. The pyroclastic flows destroyed many buildings in the village of Harris north of Sourfri?re Hills, and the Montserrat Volcano Observatory described the dome collapse as the most severe incident since May 2006.
