Russian emergency services have reported an abnormally high number of fires in the Omsk oblast of southwest Siberia. On April 22, 2021, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured this image of fires in the region. As of April 28, smoke from the fires was still visible.
Wildfire smoke has traveled about 700 kilometers (400 miles) east toward Novosibirsk, Russia’s third largest city. Citizens reported thick smoke reducing visibility on roads, and authorities issued a “black sky” air quality warning in Novosibirsk on April 27.
