Broadband seismic data acquired during the Hi - CLIMB experiment are used to study seismic events and path propagation in the Nepal Himalaya and the south - central Tibetan Plateau. The 2002 – 2005 experiment consisted of 233 stations along a dense 800 km linear north - south array extending from the Himalayan foreland into t he central Tibetan Plateau. The main array was flanked by a 350 km x 350 km sub - array in southern Tibet and central and eastern Nepal. The dataset provides an opportunity to obtain seismic event locations for ground truth (GT) evaluation, to determine sour ce parameters, and to study distance evolution of seismic coda for yield estimation in low Q regions.
