On April 3, 2000 ASTER captured this image of the erupting Mt. Usu volcano in Hokkaido, Japan. This false color infrared image, covering an area of 18 km (13 miles) by 22 km (15 miles), of Mt Usu volcano is dominated by Lake Toya, an ancient volcanic caldera. On the south shore is the active Usu volcano. On Friday, March 31, more than 11,000 people were evacuated by helicopter, truck and boat from the foot of Usu, that began erupting from the northwest flank, shooting debris and plumes of smoke streaked with blue lightning thousands of feet in the air.
