The NASA Terra and Aqua satellites on Wednesday registered some 100 fewer hotspots than on Tuesday, according to the ScanEx website that receives information from the satellites.
The Aqua satellite, equipped with an atmospheric infrared sounder, and Terra, equipped with a thermal emission and reflection radiometer, registered 494 hotspots from fires across Russia on August 11, compared with 582 just a day earlier.
The satellites also registered significant reduction of hotspots in worst fire-ravaged Ryazan and Moscow regions.
The decrease in the number of hotspots identified is partially due to cloud coverage in several Russian regions. "Atmospheric front is currently passing through Voronezh, Lipetsk, Ryazan, Vladimir and Ivanov regions. In fact, all the western half of Ryazan region is covered with thick clouds, that's why we can't speak about strong decrease in number fires," Nadezhda Pupysheva from ScanEx said.
The number of hotspots in Ural and Siberian regions grew substantively. The number of hotspots increased dramatically on Wednesday in Sverdlovsk region, to 136 from just 24 on Tuesday.
A scorching heat wave has gripped much of European Russia since mid-June, which coupled with the worst drought since the 1970s has made the countryside particularly susceptible to wildfires.
Thousands of emergency workers and military personnel have been working round the clock for almost three weeks to fight the fires in 22 regions, which have so far killed more than 50 people and left over 3,500 homeless. The immediate economic cost of the fires has been estimated at $15 billion.
Prime Minister Vladimir Putin on Tuesday took part in extinguishing wildfires in Ryazan Region on board an amphibious firefighting airplane. He dumped approximately 24 tons of water from aboard a Be-200 amphibious firefighting plane on forest fires some 200 kilometers southeast of Moscow, extinguishing two of them completely.
