Gigantic paleolandslide associated with active faulting along the Bogd fault (Gobi-Altay, Mongolia)

On the basis of analyses of satellite imagery, aerial photographs, and field observations, we describe the occurrence of one of the largest paleolandslides (50 km³) ever recognized in an intracontinental domain. The slide occurred along the active Bogd fault in the Gobi-Altay mountain range in Mongolia. Morphological and structural analyses of the relationships between the landslide and the area affected by active tectonics suggest that this gigantic mass movement was associated with surface faulting during a strong earthquake.
