I thought it would be useful to provide a compilation of images of the landslides triggered by the Sumatra earthquake. ReliefWeb is reporting that over 1000 landslides were triggered: “Landslides have hindered relief efforts in some areas. The West Sumatra Satkorlak reported at least 1,000 landslide spots in Gunung Tigo highlands, located between Padang Pariaman and Agam districts. Six helicopters carrying food and medical supplies were dispatched to the highlands as landslides blocked roads.” Interestingly, the landslides appear to be highly mobile, (comparatively but not very) shallow flows in deeply weathered soils. They have run out over quite large distances and in some of the images there appears to be large amounts of water present.
