Hours after a 2.9 tremor struck Chae Hom District in Lampang, two minor earthquakes have been recorded in Mae Taeng District today, Oct. 25.
The first little shake to register in Mae Taeng – 2.3 on the Richter scale struck at 2:20 p.m. at 19.18N 99.05 E, just to the north of the Mae Ngat Somboon Chon Dam at a depth of five kilometers.
The second, registering 2.4, struck at 2:26 p.m. at 19.16N 99.07E, within the waters of the dam itself at a depth of two kilometers.
Seismic activity in northern Thailand is not uncommon but three tremors in one day is fairly rare, be it three minor earthquakes struck San Sai over two days back in September.
Multiple minor earthquakes are often a sign of stresses in fault lines that later result in larger earthquakes. The largest earthquake ever recorded in Thailand, 6.1 struck on May 5, 2014 causing significant damage in Chiang Rai and was felt all over Chiang Mai and as far south as Bangkok.
