Hotspots are multiplying in Thailand and neighboring countries, which worsens the smog risks in the country.
The Agency for the Development of Geoinformatics and Space Technologies (GISTDA) published on Monday, March 9, a report on the hot spots detected thanks to data from the Suomi NPP satellite of the VIIRS system.
She indicated that Thailand counted no fewer than 1 136 hot spots, forest areas remaining the primary target of forest fires.
Zoom on the affected zones

A zone‑by‑zone analysis revealed that hot spots were distributed as follows in the risk areas:
- Protected national forest zones: 356 hotspots
- Conservation forest zones: 340 hotspots
- Agricultural zones: 167 hotspots
- Community zones and others: 144 hot spots
- ALRO agrarian reform zones: 115 hot spots
- Highway corridor zones: 14 hotspots
These figures reflect a situation d’forest fires that severely impacts ecosystems, particularly in densely forested areas, and could also exacerbate dangerous levels of fine particle pollution PM2,5.

Thailand is not the only country facing this crisis.
In the entire ASEAN region, a large number of hotspots continue to be detected, which could contribute to transboundary pollution.
The figures are as follows:
- Myanmar: 4,965 hot spots
- Cambodia: 1,056 hotspots
- Laos: 800 hotspots
- Vietnam: 262 hot spots
- Malaysia : 58 hot spots
Satellite data from Suomi NPP helps authorities assess the situation and deploy more precisely in affected areas in order to contain incidents.
The public and concerned agencies can follow real-time reports on hot spots and verify disaster-risk zones on the official GISTDA site: disaster.gistda.or.th/fire
