What does this image series show? Dark, fresh lava flows and ash-covered areas stand out clearly against the older surface; the white puffs are clouds or steam-and-ash plumes. The heat-signal numbers come from our own satellite measurement, and on the volcano map they refresh every half hour. The series grows daily whenever a clear image is captured.
