Activity at Montserrat’s Soufrière Hills Volcano continues to ebb and flow. Growth of the lava dome on the volcano’s summit has led to numerous pyroclastic flows, some of which nearly reached the ocean. The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Aqua satellite acquired this natural-color image on November 28, 2009, at 1:40 p.m. local time. Roughly 3 hours before, the Air Force Weather Agency reported an ash plume reaching to flight level 120 (3,700 meters) stretching west-northwest 130 nautical miles (240 kilometers) from the volcano.
After 10 months of relative quiet, Soufriere Hills Volcano on the Caribbean island Montserrat resumed activity in early October 2009. It remained active in early 2010, covering large areas with pyroclastic flows.
