Satellite data revealed catastrophic, widespread flooding in Thailand’s southern Hat Yai district, with vast areas submerged under life-threatening depths, impacting over 150,000 people and critical infrastructure.
The Geo-Informatics and Space Technology Development Agency (GISTDA) reported the dire situation on November 25, 2025. Their analysis utilized Sentinel-1A satellite data from the previous day.
Most of Hat Yai district experienced severe floodwaters, with depths ranging from 2 to 3 meters. This level was described as “head-deep,” posing an extreme danger to life and property.
The deluge has affected approximately 150,230 residents. Over 25,102 households have also been impacted by the flooding.
Critical infrastructure has sustained significant damage. Forty-seven schools and eight hospitals are among the affected facilities.
More than 536 kilometers of transportation routes have been rendered impassable. This has severely disrupted mobility and aid efforts.
GISTDA employed a HAND Model technique to accurately assess the water depth. Some areas recorded extreme depths exceeding 4 meters, while other zones saw “waist-deep” levels of 0.5 to 1 meter.
The agency emphasized the urgent need for aid. GISTDA has forwarded its analytical data to key disaster management agencies. This information is intended to serve as a crucial database for rapid decision-making and rescue operations.
The public can monitor the ongoing flood situation in near real-time. Information is available on GISTDA’s website or through their “Check Nam” application for iOS and Android devices.
