The tsunami penetrated at least five kilometers on Earth

At least five miles. Is the minimum distance landfall 'tsunami' caused by an earthquake in Japan as a satellite image released by NASA and taken Sunday 13 March, the first day that weather conditions have allowed. A spectacular photo of in black and dark blue, you can see the area flooded by the sea in the vicinity of Sendai, the most affected by the earthquake.

Image much more interesting compared to other space provided by agency, 26 February, in which the area is undamaged. Two photographs taken by the Aqua satellite on March 13, and the Terra-February-treated with infrared and visible light to highlight the various areas of the zone: bright green for areas with vegetation, brown for earth, light blue for snow, dark brown for the city and black and dark blue for water.

In addition to appreciating the area most affected by the destructive tsunami, the picture is to make an estimate of the area affected by the disaster. Through Google Planimeter type tool, which allows calculating areas on aerial maps, we can see that the main affected area, at the center of the image-occupies about 130 square kilometers.

Which together with other adjacent areas would lead to a balance of not less than 170 square kilometers. An area in which, for example, would fit the municipalities of Getafe (78 km2) and Las Rozas de Madrid (60 km2), equivalent to more than one quarter of the city of Madrid (605 km2) and occupy more than the entire city of Barcelona (101 km2).

Two photographs clarifying the importance of this natural disaster, moreover, are accompanied by the original natural color where, in the same area, you can clearly see a large column of smoke.
