NASA MODIS Image of the Day: December 26, 2008 – Plume from Soufriere Hills Volcano
The Soufriere Hills Volcano on the Caribbean island of Montserrat remained active in late December 2008.
The MODIS on NASA’s Aqua satellite captured this image of the area on December 20, 2008.
In this image, the volcanic plume is most intense near the volcano, from which it blows west-southwest. Changing wind directions carry the plume southward, creating a smoky clockwise arc southwest of the volcano. In the south, the plume mixes with clouds. According to the Montserrat Volcano Observatory’s weekly report for December 12-19, 2008, Soufriere Hills described lava extrusion from the Soufriere Hill’s dome at roughly the same time as increased pulses of volcanic ash, although the two events were not necessarily related to each other. Soufriere Hills is a stratovolcano composed of alternating layers of hardened lava, solidified ash, and rocks ejected by previous eruptions. In 1995, a series of major eruptions from this volcano eventually destroyed the island’s capital city of Plymouth. Prior to that event, a seventeenth-century eruption was the only historical eruption recorded from this volcano. The volcano experienced an explosive eruption in early December 2008, and steadily released plumes afterwards.
