WE PLAN TO INVESTIGATE GEOLOGIC AND TOPOGRAPHIC SETTINGS AND TRIGGERS OF LARGE HISTORIC PRE-HISTORIC AND FUTURE LANDSLIDES IN THE HIMALAYA AND KARAKORAM INCLUDING RIVER DAMMING AND OTHER ASSOCIATED HAZARDOUS EVENTS OF TRANSBOUNDARY CONSEQUENCES. THE REGION OF INTEREST INVOLVES THE INTERNATIONAL BORDER AREAS WITHIN THE LARGER REGION DEPICTED IN FIGURE 1. WE WILL MODEL SUSCEPTIBILITIES OF THE TERRAIN TO PRODUCE SIMILAR LARGE LANDSLIDES IN THE FUTURE DUE TO ICE MELT SEISMICITY OR STOCHASTIC FAILURES. WE WILL USE U OF A S DISTRIBUTED MEMORY CLUSTER TO COMPUTE SEISMIC WAVE PROPAGATION AND SURFACE INTERACTION IN THE COMPLEX TOPOGRAPHY AND FIRST-ORDER GEOLOGIC STRUCTURE OF THE 2015 GORKHA-EARTHQUAKE-AFFECTED HIMALAYAN REGION AND THE 2005 KASHMIR EARTHQUAKE AREA IN THE KARAKORAM. SHAKING-RELATED LANDSLIDE SUSCEPTIBILITY WILL BE TESTED USING OUTCOME OF THE 2015 GORKHA EARTHQUAKE; MONSOON RELATED LANDSLIDES WILL BE EVALUATED NEARBY BUT WHERE SEISMICITY WAS WEAK.
