The two satellite photos above from the US space agency Nasa show the devastating affect of Cyclone Nargis which swept over the Irrawaddy delta region of Myanmar on Saturday.

The image on the left taken in April 15 shows the Irrawaddy river flowing south and splitting into numerous distributaries. 


Rivers and lakes are sharply defined against a backdrop of vegetation and fallow agricultural land.

The image on the right taken on May 5 shows the entire coastal plain is flooded after the area took a direct hit from the cyclone. 

The city of Yangon (located by the red rectangle) is almost completely surrounded by floods.
