Detailed satellite images of the territory of Japan were received, where a series of earthquakes were registered on March 11 in its north-eastern parts. According to the Main Meteorological Service of the country the 8.9 magnitude earthquake was the biggest in the history of the country.
According to the government of Japan the International Charter “Space and Major Disasters” started to operate. Since morning March 12 world satellite Operators conduct optical imagery of the damaged areas in Japan.
Images from IKONOS satellite were acquired by the request from ScanEx RDC and submitted on-line to the EMERCOM of Russia. Analysis of the Tokyo districts did not reveal major destructions, which testifies to high seismic resistance of buildings. However, eastern coastline of the country suffered much more damage.
REFERENCE:
— Three quakes were registered in the morning of March 11 one after another with the earthquake source at depths from 24 to 32 kilometers. The quakes that followed were much weaker than the first onå, which attained the record magnitude of 8.9. Aftershocks were weaker, - noted professor of the MSU’s Geography Department Andrei Lukashev.
Information agencies reported that a series of quakes triggered a tsunami that in some regions was over 10 meters high. In some districts the tsunami wave smashed and swept away houses and cars from the roads. A huge wave covered fields and roads destroying buildings and facilities. A fire occurred at the nuclear power plant in Fukushima. Authorities announced a state of emergency in the area of fire due to threat of radiation. Over two thousand people were evacuated from the nearby districts.
