Geological Survey Alerts 15 Provinces To Landslides, Flooding
Thailand's Geological Survey warns 15 provinces of landslide and flooding risks through July 4 as a monsoon trough brings heavy rainfall exceeding 100mm in 24 hours across northern and southern regions.
On July 3, 2025, the Disaster Geology Operation Center under the Department of Mineral Resources warned of heightened risks of landslides and flash flooding across 15 provinces including Mae Hong Son, Chiang Mai, Chiang Rai, Tak, Nan, Phayao, Phichit, Chanthaburi, Trat, Ranong, Phang Nga, Phuket, Krabi, Trang, and Surat Thani through July 4. The alert was issued due to a monsoon trough moving across the northern and upper northeastern regions, combined with strong southwestern winds over the Andaman Sea and Gulf of Thailand, resulting in continuous heavy rainfall exceeding 100 millimeters in 24 hours and initial flash flooding in some areas. The department urged volunteer monitoring networks to remain alert, continuously measure rainfall, and promptly alert residents and relevant agencies of any landslide or flash flood incidents, following established emergency response procedures.
