An earthquake measuring magnitude 4.3 was recorded in Tibet on Sunday, the National Center for Seismology (NCS) reported. The event occurred at a depth of 145 km. In a post on X, the NCS reported: “EQ of M: 4.3, On: 29/03/2026 10:54:27 IST, Lat: 30.187 N, Long: 84.280 E, Depth: 145 Km, Location: Tibet.”
A separate, smaller event was recorded in the same region two days earlier. On March 27 the NCS reported a magnitude 3.2 quake at a depth of 40 km: “EQ of M: 3.2, On: 27/03/2026 04:18:47 IST, Lat: 28.842 N, Long: 89.290 E, Depth: 40 Km, Location: Tibet.”
The Tibetan Plateau is seismically active because it sits at the collision zone between the Indian and Eurasian tectonic plates. This ongoing convergence has thickened the crust and uplifted the Himalayas and plateau, producing a complex pattern of faults and frequent earthquakes.
Within the plateau, tectonic behavior varies regionally. Strike-slip faulting is most common in the north, while the south is dominated by east–west extension accommodated by north–south-trending normal faults. Seven north–south rifts and normal faults in southern Tibet were first mapped from satellite imagery in the late 1970s and early 1980s; these structures began forming when extension started roughly 4–8 million years ago.
Large, damaging earthquakes in Tibet—those around magnitude 8.0—tend to occur on strike-slip faults. Normal-faulting events are generally smaller; for example, in 2008 the plateau experienced several normal-fault earthquakes with magnitudes between about 5.9 and 7.1.
