Land Fissures Detected in Mae Hong Son Prompt Safety Concerns
Authorities in Mae Hong Son are monitoring land cracks near Ban Po So, fearing that heavy rainfall could trigger landslides affecting local homes and schools.
On August 30, 2026, officials in Mae Sariang District, Mae Hong Son, reported the discovery of significant land fissures and soil movement near Ban Po So in Sao Hin Subdistrict. According to Khaosod Online, the cracks span approximately 130 meters in length with depths ranging from 50 to 80 centimeters. The affected area is situated on a slope directly above a residential community and a school located near the river.
Local authorities have identified a high risk of landslides should heavy, accumulated rainfall occur in the region. Consequently, officials have ordered close monitoring of both Sao Hin and Mae Khong subdistricts. Village leaders and local administrative organizations are tasked with tracking daily rainfall levels to provide timely warnings to residents. Coordination is underway with the Salawin Wildlife Sanctuary and geological experts to conduct a thorough assessment of the site.
These fissures were first identified in June 2026, and recent observations indicate that the cracks have expanded since their initial discovery. For residents and visitors in the area, the situation remains a point of concern as the stability of the slope depends heavily on weather conditions. While experts have been requested to evaluate the geological threat, the full extent of the risk and the necessity for potential evacuations remain to be confirmed pending further technical analysis.
