Satellite imagery shows seasonal changes along world's 10th-longest river.
The Amur River is the world’s tenth longest, flowing east along the Chinese-Russian border before turning northeast and ultimately emptying into the Strait of Tartary. We have previously shown images of the river when it had spilled over its banks or when fires burned nearby. These images show that the river is also a place of stunning beauty, as autumn foliage paints its banks yellow and orange.
The Operational Land Imager on Landsat 8 acquired these images on September 30, 2019. They show three locations along a 120-kilometer stretch of the lower Amur, northeast of Komsomolsk-on-Amur in the Russian Far East.
