At least 30% or more of all homes in the northern Nepal and southern Tibet region were totally destroyed. In the Kathmandu Valley, 400 buildings crumpled to the ground, burying many occupants residing in them. One of the two towers of the Dharahara, built by Bhimsen Thapa collapsed completely, and was never rebuilt. The other tower suffered minor damage and was repaired shortly after. The new tower stood over the city until 1934 when the magnitude 8.0 earthquake would knock it down again. The other was partially damaged and quickly restored, only to be destroyed once again during the 1934 Bihar earthquake. The home of Matabarsing Thapa, was completely destroyed, and the garden houses belonging to Bhimsen Thapa became unfit for occupancy. In all, a total of 18,000 buildings were totally wiped out, with over 4,000 having collapsed in the Kathmandu Valley region.
