Geological Agency Warns 14 Provinces of Heavy Rains, Landslides
Thailand's Geological Disaster Operation Center issued a landslide and flash flood warning for 14 provinces through August 9, as heavy monsoon rains exceed 100mm daily across northern and southern regions.
On August 7, 2025, the Geological Disaster Operation Center of the Department of Mineral Resources under the Ministry of Natural Resources and Environment issued an alert for landslides and flash floods expected over the next 1-3 days. The warning covers 14 provinces across northern, northeastern, eastern, and southern Thailand: Tak, Mae Hong Son, Chiang Mai, Chiang Rai, Nan, Phayao, Phrae, Uttaradit, Phichit, Phetchabun, Chanthaburi, Trat, Ranong, and Phang Nga, with heightened vigilance required from August 7-9, 2025.
The warning was triggered by a monsoon trough passing over the upper northern and upper northeastern regions, interacting with a low-pressure system in the Gulf of Tonkin, combined with a strengthening southwest monsoon. This has caused continuous heavy rainfall exceeding 100 millimeters in 24 hours in some areas, with flash flooding already occurring in several locations and potential for landslides increasing.
The Department of Mineral Resources has requested volunteers and network coordinators to maintain continuous monitoring and rainfall measurements. Communities are urged to remain on alert and report any landslide or flash flood incidents to relevant authorities, following established disaster response protocols.
