Northeast India has five major tectonic domains having its own evolutionary history and characteristics. The region is seismically one of the six most active regions of the world the other five being Maxico, Taiwan, California, Japan and Turkey. It has experienced 19 large (M ≥ 7) including 3 great earthquakes (M ≥ 8). The present study aimed to correlate these earthquakes with the tectonic setting of the region and this is done by plotting the epicenters of the earthquakes to the tectonic map of the area. Indo-Burma range has experienced maximum number of large earthquakes in comparison to other domains indicating that along the plate boundary, subduction process is mostly related to the large earthquake than collision process. Intra plate activity is also responsible for some of the large earthquakes and Kopili lineament of Assam Valley was the source of such two events. The great earthquake of 1897, 1912 and 1950 are related to Po-chu –Fault in Assam-Tibet Border, Kyaukkyan fault system in Shan Plateau and Oldham Fault in Shillong Plateau respectively.
