Bangkok: Thailand's hotspot situation has surged to a record high, with 5,052 points identified, particularly dense in the northern region. Meanwhile, neighboring countries, especially Myanmar, have also reported numerous hotspots, exceeding 8,000 points, highlighting the ongoing severe risk of transboundary haze.

According to Thai News Agency, the Geo-Informatics and Space Technology Development Agency (Public Organization), or GISTDA, reported data from the Suomi NPP satellite using the VIIRS system on April 3, 2026. This data revealed a significant increase in hotspots in Thailand, reaching 5,052 points.

The incidents are categorized by area type, with the highest concentration in protected forest areas at 2,962 points, followed by national forest reserves with 1,436 points. Agricultural areas accounted for 291 points, land reform areas 189 points, community and other areas 162 points, and areas along highways 12 points.

The data indicates that most hotspots are concentrated in the northern region, which is characterized by mountainous and forested terrain, making wildfire control challenging. This situation is likely contributing to the PM2.5 air pollution in several provinces.

Neighboring countries are also experiencing high levels of hotspots, with Myanmar reporting the highest number at 8,551, followed by Laos with 4,934, Vietnam with 896, Cambodia with 838, and Malaysia with 67. These figures are significant contributors to the transboundary haze problems in the region.

GISTDA emphasized the need for close monitoring of the situation, particularly in northern Thailand, where PM2.5 levels remain elevated. The public can access additional real-time information on hotspots through the GISTDA website to assist in monitoring and responding to the situation appropriately.
