A lot has been going on around the world, volcanically speaking, over the past few weeks, and the NASA Earth Observatory has been featuring some wonderful satellite imagery of current volcanic events.
Submarine eruption in the Tonga Islands (acquired 26 March 2009): an ASTER image from NASA’s Terra satellite showing new land created by the eruption at Hunga Ha’apai, sediment-laden water around the island, and evidence of the destruction of vegetation by the volcanic action.
Plume from Mount Redoubt (acquired 26 March 2009): a series of images captured by the Geostationary Operational Environmental Satellite (GOES) of the plume produced by Mount Redoubt between 09:00 and 11:30 local time on 26 March 2009.
Plume from Rabaul Volcano (acquired 3 April 2009): a MODIS image from NASA’s Aqua satellite shows an off-white plume (suggesting mainly water vapour content) from Rabaul blowing away to the south-east.
Sulfur dioxide plume from Isla Fernandina (aquired 14 April 2009): the Ozone Monitoring Instrument (OMI) on NASA’s Aura satellite captured data on the SO2 plume emitted by the eruption of Fernandina in the Galapagos Islands.
Eruption from Llaima volcano, Chile (acquired 16 April 2009): the Advanced Land Imager (ALI) on NASA’s Earth Observing-1 satellite captured a stunning unobstructed view of Llaima’s barren, lava-layered summit area.
The NASA Earth Observatory is currently celebrating its 10th anniversary, and is inviting everyone to vote on their favourite Images of the Day from the last ten years of wonderful satellite imagery. Seven of the fifty finalists are volcano-related, and any one of them would be a worthy winner.
