Abstract: North-East India is located in one of the most seismic prone area of the world. India has faced several devastating earthquakes in the past. The largest of these have originated in the Himalayan plate boundary region, which has remained a region of great scientific and engineering interest. Not surprisingly, considerable data and earthquake related literature are available about the northern part of India. On the other hand very little information is available seismological about North-East India, which is the study area for present study.In spite of this only few attenuation relationships are available for this region and because of this I was prompted to make an attenuation relationship only for this region. An attenuation relationship for peak horizontal ground accelerations for North-East region in India has been developed with data base consisting of 214 peak ground horizontal accelerations from 23 earthquakes recorded by strong-motion stations and arrays in India. The database consists of earthquake from 1986 to 2010, with magnitude ranging from 4 to 6.8. The attenuation relationship proposed is log(A)=-1.2151 +0.5161M- 1.5299 log (R+eo.5873M) where A is the peak ground acceleration (g), M is the magnitude, and R is the hypocentral distance from the source. The residual sum of squares is 0.2855. Comparison with other such attenuation relationships has been made. The attenuation relationship needs improvement when more data become available in future. The site characterization of the strong motion accelerographs station has been done and is discussed in chapter 4. Comparison of the newly develop attenuation relationship with the relationship given by Sharma (1998), and Abrahamson and Litehiser (1989) for magnitudes of 5.0, 6.0, 7.0 and 8.0 have also been done.
