The above images were captured over a 50-day flooding period in Pakistan. The first image, from July 19, shows the Indus River (blue), irrigated lands (green), and bare lands (pink), all before the flooding became apparent. In the second image, from August 11, the river has swollen significantly. By the time the third image was captured on September 7, the Indus had split and created a parallel river of comparable width.

Flooding has so far destroyed 8.9 million acres of Pakistani farmland. Over 1700 people have died and millions have been displaced.
