Immagine del satellite NASA mostra il pennacchio di cenere fare ombra ad ovest

This image provided by NASA shows an image taken by a NASA MODIS satellite acquired at 1:15 a.m. EDT on May 22, 2011 shows the ash plume from the Grimsvotn volcano casts shadow to the west. The Grimsvotn volcano began erupting on Saturday, May 21 sending clouds of ash high into the air. The amount of ash spewing from the volcano tapered off dramatically on Tuesday, however, said Elin Jonasdottir, a forecaster at Iceland’s meteorological office. The blue dots are data dropouts probably caused by the very bad light in the shadow of the plume.
