Abstract

A method of seismic zonation based on deterministic modeling of rupture plane is presented in this work. This method is based on the modeling of finite rupture plane along identified lineaments in the region using the semi empirical technique of Midorikawa (1993).The seismic zonation due to large earthquakes ( M > 7) is prepared for technoeconomically important NE part of Indian subcontinent. On the basis of the value of expacted peak ground acceleration, the studied area is classified into three zones. The zone 1 is the area having expected peak ground acceleration of the order of more than 300 gals, the zone 2 is the area having expected peak ground acceleration of the order of 200 to 300 gals and the zone 3 with expected peak ground acceleration d
