The 1947 Assam earthquake occurred on 29 July at 13:43 UTC with a magnitude of Mw 7.3. The earthquake was located near the border between India and Tibet. Some sources put the epicenter in Indian, and some put it in Tibet.[2][3] In the Chinese literature, this earthquake was often located around the Nang County, Tibet.[4]

In Dibrugarh, Jorhat, and Tezpur, there were cracks in walls. Failure of electricity was reported in Guwahati.[3] The released seismic moment was about 1.5×1020 Nm.[5] The mechanism of the earthquake is not well known.[6]
