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

On the basis of analyses of satellite imagery, aerial photographs, and held observations, we describe the occurrence of one of the largest paleolandsl ides (50 km(3)) ever recognized in an intracontinental domain. The slide oc curred along the active Bogd fault in the Gobi-Altay mountain range in Mong olia. Morphological and structural analyses of the relationships between th e landslide and the area affected by active tectonics suggests that this gi gantic mass movement was associated with surface faulting during a strong e arthquake.
