UPDATE 16 February 2010. The image of Soufrière Hills discussed below is today’s Image of the Day at the NASA Earth Observatory.
Many thanks to Robert Simmon of the NASA Earth Observatory who forwarded this image (other versions at various pixel sizes available at NASA’s Rapid Response site) of the Lesser Antilles captured by the MODIS aboard NASA’s Terra satellite at 17:20 UTC on 11 February 2010 – just in time to catch the dome collapse event of that day at Soufrière Hills volcano on Montserrat. A cropped and labelled version of the image is below.
The dense, ashy plume thrown up by the dome collapse is clearly visible, piling up over Montserrat and trending to the east. The event began at about 17:00 UTC according to Washington VAAC, so when this image was captured the plume had not yet made its way far across the ocean. Subsequently ashfall from this event occurred to the south-east, in Guadeloupe and Dominica, and in Martinique, St Lucia and Barbados. The ash caused extensive disruption including flight cancellations. Ash from earlier activity can be seen floating on the surface of the sea to the north and east of Montserrat, producing a faint grey-green stain.
