Abstract

Yigong(Yig.) Landslide occurred at 20:00, 04/09/2000 in Zhamulong(Zha.) Gully located in the southern-east part of Tibet in China. The huge rock collapse -- landslide occurred at first in the upper part of Zha. Gully, then that immediately changed into debris-flow and rush down for about 8 km, in two or three minutes, blocked the Yig. River course and formed a plateau lake -- Yig. Lake, the natural dam covered about 4.5 km², with a 3 x 10⁸m³ of volume. At 21:30, 06/10/2000, Yig. Landslide dam burst, about 22 x 10⁸m³ of torrent pour down lower reach causing serious economic loss and ecologic disaster. By satellite remote sensing technique, the process from Yig. Landslide occurrence to after the Yig. Lake burst, had been monitored, and proper prediction was made.
