Tectonic Summary
The March 28, 2025, M7.7 earthquake near Mandalay, Burma (Myanmar), occurred as the result of
strike slip faulting between the India and Eurasia plates.
Focal mechanism solutions indicate that slip occurred on either a
north-striking, steeply-dipping, right-lateral fault, or a
west striking, steeply-dipping, left-lateral fault. The
finite fault solution indicates a north striking right-lateral fault. This focal mechanism and finite fault solution are consistent with the earthquake potentially occurring on the
right-lateral Sagaing Fault that lies in the
fault zone that defines the plate boundary between the Indian and Sunda plates.
While commonly plotted as points on maps, earthquakes of this size are more appropriately described as slip over a larger
fault area. The finite fault solution indicates the size of the March 28, 2025 event is about 200 km by 20 km (length x width).
This region has experience similar
large strike slip earthquakes, with six other magnitude 7 and larger earthquakes occurring with about 150 miles (250 km) of the March 28, 2025 earthquake since 1900. The most recent of these was a magnitude 7.0 earthquake in January 1990, which caused 32 buildings to fall. A magnitude 7.9 earthquake occurred south of today’s earthquake in February 1912. Within this broad zone of tectonic deformation, other large earthquakes, including a magnitude 7.7 earthquake in 1988, have caused dozens of fatalities.
