The 2003 Taungdwingyi earthquake struck central Myanmar at midnight, on 21 September with a magnitude of Mwb  6.6.

[2] The earthquake occurred due to shallow strike-slip faulting.

Shaking was felt in Bangkok and Chiang Mai.

Damage was severe, over 180 ritual houses were destroyed, including a primary school that collapsed.

[10] 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.
