| Abstract: | In this paper, ground motion during six past devastating earthquakes and one possible future event in the northeastern part
of India is estimated by seismological approaches. Considering uncertainty in the input source parameters, a series of ground
motions have been simulated. The peak ground acceleration (PGA) and response spectra at important cities and towns in the
epicentral regions of these events are obtained. The PGA distribution over the entire northeastern region of India, encompassing
the epicenter, is presented in the form of contours. The obtained results can be used for the seismic analysis and design
of structures in this region. |
