On February 27, 2007, the Stromboli Volcano underwent a strong
eruption. According to the BBC News, two new craters opened on
the volcano’s summit, producing twin lava flows. One of those
lava streams reached the sea the same day, sending up plumes of
steam as the scalding lava touched the cool water. Although
authorities did not anticipate an evacuation of the volcanic
island, they restricted access to high-risk areas. According to
Volcano Discovery, seismic activity, including rockfalls,
continued several days. On March 8, 2007, the Advanced
Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on
NASA’s Terra satellite captured these images. The larger image
is an infrared-enhanced, “false-color” image in which bare
ground is gray, water is dark blue, and vegetation is red. The
inset image is a thermal infrared image showing energy that
humans can’t see but can sense as heat. Clouds, possibly mixed
with steam, cover the new lava flow in the larger image, but in
the inset, the hot flow makes a yello
