توضیح
English: Residents in India’s state of Kerala are reeling from a "once-in-a-century" flood that displaced nearly a million people, caused hundreds of fatalities, and washed away homes. The region started receiving heavy rain on August 8, 2018, but news reports state that the flooding was worsened by releases from dams.

The Operational Land Imager (OLI) on the Landsat 8 satellite acquired the left image (bands 6-5-3) on February 6, 2018, before the flood. The Multispectral Instrument on the European Space Agency’s Sentinel-2 satellite acquired the right image (bands 11-8-3) on August 22, 2018, after flood water had inundated the area. The images are false-color, which makes flood water appear dark blue. Vegetation is bright green.

Several rivers throughout the region spilled over their banks. Water from the Karuvannur River ran through 40 villages, and washed away a 2.2 kilometer (1.4 mile) stretch of land connecting two national highways. Elevated water levels along the Periyar River displaced thousands of people.
