Sumatra fire hotspots rise as haze deepens in Riau, Malaysia's regional share stays small
Satellite monitoring shows an increase in fire hotspots on Sumatra, with the majority located in its southern region. The smoke from the fires has spread into Riau, where air quality officials have warned of health risks and advised the public to limit outdoor activity. In neighboring Malaysia, the number of recorded hotspots remains low relative to the broader Southeast Asian region. Officials note that hotspot counts can sometimes overstate the actual number of fires because the same location may be recorded repeatedly until the blaze is fully extinguished.
