Following the 8.2-magnitude earthquake in Mandalay, Myanmar on Friday afternoon, tremors resonated through various regions of Thailand. Residents in northern and central areas, including Bangkok, reported feeling the quake’s effects, leading to significant public concern and criticism directed at authorities for not issuing advance warnings.
Veerachart Wiwekkawin, a senior geologist from the Department of Mineral Resources, explained that the earthquake originated from the Sagaing Fault, which extends from Mandalay to Yangon. Despite being a considerable distance from Thailand, it generated seismic waves that were strong enough for residents in northern and central Thailand, and notably Bangkok, to perceive the tremors.
“The geological configuration facilitated the earthquake waves’ transmission, particularly the low-frequency vibrations that enabled tall structures in Bangkok to resonate more with the tremors,” said Veerachart. This phenomenon made the experiences more pronounced for individuals in high-rise buildings.
He further elaborated on aftershocks, noting that they typically decrease in magnitude over time, with no foreseeable significant threats to the Thai population. The expert reassured that despite the initial shock, the situation remains largely safe.
