The Shillong Plateau is a plateau in eastern Meghalaya state, northeastern India. The plateau's southern, northern, and western ridges form the Garo, Khasi, and Jaintia Hills respectively.
The plateau shows numerous fracture lineaments in satellite images and has been subjected to extensive compressive forces in the N-S and E-W direction. Several deep earthquakes point to tectonic activity in the mantle, such as from the 1897 Assam earthquake along the blind Oldham Fault.
