Color (472 kb) The Moderate Resolution Imaging Spectroradiometer
(MODIS) on NASA’s Terra satellite captured this view of the
erupting volcano. The plume is largely made of steam rising from the melting
ice above the volcano, but ash is mixed in as well. Against the white of the Vatnajokull Ice Cap, the white eruption plume is
difficult to see in the true-color image. The false-color image, which shows
ice as bright red, provides the contrast needed to see the steam plume. As
the plume is blown north, the steam dissipates, and the dark ash is more
visible. The shadow on the snow along the top edge of the image may be ash on
the glacier. As the eruption continues, flooding is likely around the volcano. So
far, some of the glacier-fed rivers southeast of the volcano have flooded,
and more floods are expected. The high-resolution images provided above are at MODIS’ maximum
resolution of 250 meters per pixel. The MODIS Rapid Response Team provides
both the true
and false
color images in additional resolutions. NASA images courtesy Jacques Descloitres, MODIS Rapid Response
