Abstract

Earthquakes occurrences posed a serious threat to man as they are unpredictable and destructive. The entire states of Northeast, India falls under seismic zone V- the region most susceptible to destructive seismic activity. With this background, it is of utmost importance to study the impact of seismic event on anthropogenic assets. The present study was carried out in Kohima, the capital of Nagaland, India. Estimation of seismic event was calculated based on five time periods for deriving the response spectra. The buildings were classed into four classes (W1, C3L, C3M and C3H) based on parameter such as- material used, number of floor etc. The technique adopted for the study was based on HAZUS model developed by FEMA. The damage probability was further classified into no damage, slight damage, moderate damage, extensive damage and complete damage. The significance of the study lies in the application of HAZUS model for estimating the building responses to an earthquake event.
