Residents rattled by two quakes as engineers review infrastructure

The northern province of Nan experienced two tremors early yesterday, following a previous earthquake that caused damage to a hospital in Nakhon Si Thammarat on May 7.
According to the Earthquake Observation Division of the Thai Meteorological Department, the tremors in Nan registered magnitudes of 1.7 and 1.5 on the Richter scale, occurring at 4.04am and 4.52am, respectively. Local officials noted that both tremors originated one kilometre underground in tambon Yap Hua Na of Wiang Sa district.
These events followed a 3.0-magnitude quake on May 7 in tambon Saira, Chawang district, Nakhon Si Thammarat. The earlier earthquake, also at a depth of one kilometre, took place at 5.31am and was perceptible in Chawang and Phipun districts, as reported by the division.
Chawang Crown Prince Hospital was evacuated as a safety measure. Public works officials later assessed the hospital and found some cracks resulting from the earthquake, but they assured that the building’s structure remained safe, reported Bangkok Post.
Additionally, groundwater wells suffered damage in multiple areas; however, the reservoirs of Kathun and Klong Din Daeng in Phipun were unaffected.
