On the basis of the information on earthquake occurrence collected through questionnaires on damage survey, isoseismals VI to VIII on Modified Mercalli scale have been drawn and compound with the intensity based on spectral accelerations. Maximum intensity VII+ was observed at Sharan, Dhankuta, Tehrathum, Udaypur and Ilam in Nepal and at Jogbani in Bihar. Dharan Distt. was the most affected region in Nepal where about 90% buildings were damaged. The intensity VIII was observed in and around Darbhanga district where all Kutchcha houses were severely damaged, many of them almost collapsed, and cracks developed in gr ound and many retaining walls. The elliptical shape of the isoseismals with its major axis having NE-SW trend coincides with general structural trend of the area. Records of Structural Response recorders (SRRs) town. support the views of general public, particularly in and around Darbhanga town.
