BANGKOK: A 3.4 magnitude earthquake struck Myanmar at 10.36am on Friday (Feb 13), with the epicentre located 17km southwest of Mae Sai, Chiang Rai.
The Earthquake Observation Division of the Thai Meteorological Department reported that the earthquake recorded a depth of 3km. There were no immediate reports of felt tremors.
Earlier in the morning, at 8.40am, another earthquake with a magnitude of 2.7 occurred in Myanmar at a depth of 10km. Its epicentre was located approximately 202km northwest of Mueang district in Mae Hong Son province.
Regarding recent seismic activity in Thailand, earthquakes have been recorded in Chiang Mai, Chiang Rai, and Surat Thani between Feb 11 and 23. In Surat Thani, there have been 13 earthquakes, with the epicentre in the Khao Phang area of Ban Takun district.
The Geohazards Operation Centre of the Department of Mineral Resources has stated that these earthquakes are due to the movement of the Khlong Marui Fault, which runs in a northeast-southwest direction.
The fault's left lateral strike-slip motion causes these small tremors, with earthquake intensities measured on the Mercalli scale ranging from 2 to 3 (very light), meaning that the vibrations were only noticeable to those in the immediate vicinity. - The Nation/ANN
