An earthquake affected Myanmar on 5 May 1930 with a moment magnitude (Mw ) of 7.4. The shock occurred 35 km (22 mi) beneath the surface with a maximum Rossi–Forel intensity of IX (Devastating tremor). The earthquake was the result of rupture along a 131 km (81 mi) segment of the Sagaing Fault—a major strike-slip fault that runs through the country. Extensive damage was reported in the southern part of the country, particularly in Bago and Yangon, where buildings collapsed and fires erupted. At least 550, and possibly up to 7,000 people were killed. A moderate tsunami struck the Burmese coast which caused minor damage to ships and a port. It was felt for over 570,000 km2 (220,000 sq mi) and as far as Shan State and Thailand. The mainshock was followed by many aftershocks; several were damaging. A further, related, earthquake in December was similarly sized and also occurred along the Sagaing Fault.
