A magnitude-6.3 earthquake in northern Thailand killed an 83-year-old woman when a wall collapsed on her.
Saeng Linkham, of Mae Lao district in Chiang Rai province, was the only known casualty of the quake, which struck at 6:08 pm (11:08 GMT) on Monday, a spokeswoman of the Chiang Rai Disaster Relief Centre said.
The initial quake was followed by more than 50 smaller aftershocks.
The earthquake caused blackouts, damaged roads, buildings and temples in the northern provinces of Chiang Mai and Chiang Rai.
The quake was one of the strongest recorded in Thailand, which does not sit on any major fault lines.
