Pekanbaru – A satellite has detected at least 45 hot spots in Sumatra, with almost half of them found in Riau, according to a government scientist.

Marzuki, an analyst with the Meteorology, Climatology and Geophysics Agency's office in Pekanbaru, Riau, said on Friday that the hot spots were detected by Singapore's National Oceanic and Atmospheric Administration 18 Satellite on Thursday, antaranews.com reported.

"There are hot spots distributed across Jambi, North Sumatra, South Sumatra and Aceh in almost the same numbers. As for Riau, it has the highest number of hot spots, with 22," he said.

"There might be more hot spots if the temperature remains above 33 degrees Celsius and there is little rain," he added.
