Re-photography is a powerful tool used to monitor environmental changes over time. Normally used to capture duplicate images for a specific location to see changes over decades or century long time-lines, it can be used for much shorter durations. Two images retaken less than a month apart show drastic alterations in a landscape in Russia's Far East.

According to NASA, the Aqua satellite monitored floods this summer created by extreme rainfall that occurred in the Russian northeast in August. The massive waters moved north along the entire length of the Amur River creating a long lake where the river had been. The floods have now reached the city of Komsomolsk-on-Amur, where approximately 500,000 people live.

The comparison of infrared re-photographs are indeed impressive.

As the floods continue rising, the climatic factors that created the extreme rainfall event is under investigation. Climate change is an obvious culprit.
