A pertinent question concerning seismicity in such regions is whether a preexisting fault exists and, if so, what is its reactivation interval? Our studies in the 1993 rupture zone suggest that the Killari earthquake occurred in a region of previous seismic activity. Older thrust sheets and fault gouge, presumably formed during previous episodes, were exposed in a deep trench. The studies also indicated an obsequent fault-line scarp, aligned with the current rupture zone. The morphological features in the area suggest mass removal of the upper part of the hanging wall on the southwestern side of the rupture. Existence of a prominent northwest-striking structure passing through the epicentral zone is revealed in the digital Landsat data. These data, together with the spatial trend of historic earthquakes along the northwest-striking structure, reinforce the argument that the earthquake at Killari is related to the reactivation of a preexisting fault.
