Strong motion data reveal an initial 6-s source pulse followed by 4-6 s energy reverberating within the basin. One of the striking features of the observed ground motions in the valley is that they were depleted of energy in the 0.5-10 Hz frequency range, which likely limited the severity of the structural damage compared to other possible realizations of similar ruptures. Isolated cases of liquefaction and lateral spreading of unconsolidated sediments were also observed but have not yet revealed a systematic damage pattern. Initial analysis of available data suggests that several different factors, including source and path as well as site effects, were responsible for the unusual character of the ground motions. In this paper, we review earthquake reconnaissance as well as available strong motion records from Kathmandu Valley to better understand the observations from this earthquake.
