A geologist attributed the collapse to natural geological processes, while locals in the area suspected a nearby stone mine of contributing to the incident. Geologists from the Mineral Resources Regional Office 2 in Khon Kaen inspected the affected area in Ban Wang Charoen, Huai Muang subdistrict, Phu Pha Man district yesterday, August 5. According to Orn-uma, the cavities are not expected to continue expanding underground, meaning the affected areas can be filled with soil as a short-term solution. Khon Kaen Governor Khajornkiat Rakpanichmanee said the province is preparing to declare the affected area a disaster zone. Local officials also warned that the ground continues to collapse gradually rather than in a single event, with the affected areas widening and becoming deeper over time.
