Moderate resolution satellite images, as we see them not the human element of a disaster, but the images provide perspective on the scale of a disaster. The bottom two images (previously released on the Earth Observatory) show the physical extension of the flooding of a large area from the North, South and several kilometres inland after tsunamis the island on March 11, 2011 devastated. The top image on 1 April, shows that there is still a full three weeks later are pockets of flooding, provides a sense of long-term damage wrought iron waves.
The pictures, all taken from the MODIS (moderate resolution imaging spectroradiometer) sensors on NASA satellites Terra and Aqua, the Japanese coast in the vicinity of Sendai in a combination view from visible and infrared light. This combination shows the presence of water on the ground. Water (probably a muddy color in visible light) is black or dark blue in these images. Bare earth tan-pink, plant covered ground green, and snow is Turquoise. Urban areas, such as Sendai, are cement-colored.
Although much of the flood water visible receded had on 13 March (Middle image) of 1 April, water bags such as faint shadow over the region devastated by the tsunami linger. These flooded areas allow it, to see, the extent of tsunami flooding three weeks after it occurred. The lower image shows the area on 26 February before the disaster.
The places that are still under water to the sections, which is the Japanese military are looking for more than 16,000 people still missing, are, the associated press reported. 1. April 11,700 deaths with an expected confirmed final death toll close to 25,000.
The MODIS rapid response system provides images like this twice a day.
