This is an image of the Eyjafjallajokull volcano on the southern coast of Iceland taken on April 17, 2010 by MODIS, three days after the eruption started. I chose this image because there have been several significant earthquakes from another large Icelandic volcano, Bardarbunga, indicating an eruption may happen relatively soon, and Eyjafjallajokull can be used an analog to help predict possible impacts. This eruption disrupted air traffic in Europe for days, and caused glacier melts and flooding. I like this image because at first glance it looks like it may be silt or sediment in water, however you can see the shadow of the ash plume at the volcano, and you realize just how high it is. To help estimate the height of the plume, NASA used their Multi-angle Imaging SpectroRadiometer on board Terra Satellite to create a 3D image.
