The thick haze in Sumatra and Kalimantan started to ease on Friday after the rains came sweeping through, said a spokesman of the National Disaster Mitigation Agency (BNPB).
BNPB spokesman Sutopo Purwo Nugroho said the air quality on Friday morning was better than the past three months.
"The rain over the past three days helped the air quality and visibility get better in Sumatra and Kalimantan," he said as quoted by state news agency Antara.
Sutopo also reported that hot spots had also lessened.
He said the weather in Palangkaraya, Central Kalimantan, was reportedly bright on Friday morning even though the air quality in the city was reportedly unhealthy a day before.
"We hope there will be more [rain] clouds in the areas affected by the haze," he said.
Sutopo said the Terra Aqua satellite detected one hotspot in Kalimantan, which was in South Kalimantan on Thursday afternoon. While there were 148 hotspots detected in Sumatra on Thursday: one in Bengkulu, 30 in Lampung, one in West Sumatra and 109 in South Sumatra.
The visibility in Padang, West Sumatra, was 5,000 meters; 4,000 m in Pekanbaru, Riau; 1,700 m in Jambi; and 2,000 m in Palembang, South Sumatra.
While Kalimantan reportedly had better visibility on Thursday: 1,000 m in Pontianak; 10,000 m in Ketapang, West Kalimantan; 5,000 m in Palangkaraya; and 5,000 m in Banjarmasin, South Kalimantan. (rin)(+)
