Geology
The earthquake occurred along the Gwegyo Thrust, a thrust fault running along the eastern foothills of the Pego Yoma range, and adjacent to the Sagaing Fault. Its epicenter is centered southeast of the nearby town of Taungdwingyi, at least 50 km from the Sagaing Fault and 360 km from Yangon. Shaking was felt in Bangkok and Chiang Mai.[1]
Damage and casualties
At least seven people were killed and 43 were injured. Damage was severe, over 180 ritual houses were destroyed, including a primary school that collapsed.[2] Liquefaction, sand boils and landslides were also reported.[3] The small death toll is attributed to the fact that this quake occurred around midnight, therefore the collapse of the school did not result in any injuries.
Aftershocks
Numerous aftershocks were recorded in the region. Four of them were greater than M5.0.[4][5][6][7]
