The North East India falls in district V according to the basaltic zonation map of India (BIS, 2002). The repetitiveness of occurrence of moderate and large size earthquakes is considerably high during the whole of the region. The bigger tectonic blocks establishing the NE India are the Assam-Arakan Folded Belts, the Arunachal Himalayas, the Mishmi Massif, the Shillong – Mikir plateau and the North – South Fold Belts of Tripura and the adjacent Bengal Alluvial Basin. Most of the occurrences falling in the fundamental domains of the eastward Himalayas including Mishmi mountain system, Naga Hills, Shillong-Mikir Plateau, Surma basin and abutting Bengal Alluvial Plains are of crustal origin (h<70km) except for any events in the N-W likely wedge formed block lying 'tween the Kopili and Bomdila faults.Seismic home factor or site elaboration measurement has happened recognized as the most endorsed tool in basaltic hazard assessment and risk judgment taking into account the source and home conditions taking everything in mind all probable hazards plan in a much larger scale. Therefore, basaltic site answer study and preparation of seismic microzonation maps for very populated city areas of NE India is thought-out as a measure of site-distinguishing hazard estimation. Tezpur is the governmental headquarter of Sonitpur district and it is an up growing city. The city Tezpur lies to the northern limit of the seismically active Mikir Plateau, and middle from two points a complex tectonic management. It is bordered accompanying MBT to the north, Mikir Hills to the south – southeast, Assam canyon to the ENE and Kopili lineament to the west from intense following a time plate seismic action.
