14:46 on March 11, 2011, a massive earthquake of magnitude 9.0 occurred around 130km east-southeast of Oshika Peninsula, off Sanriku. It was centered at 38.0°N, 142.9°E, with a depth of about 24km.

22. High Resolution Panoramic Aerial Photography

Using a special device on the helicopter, high resolution photos were taken and combined to make the following panoramic photos:

21. Estimated change of the flooded range extracted from Synthetic Aperture Radar satellite (TerraSAR-X) updated by PASCO #4

PASCO attempted the automatic extraction of flooded area caused by the tsunami using the information from the synthetic aperture radar satellite (TerraSAR-X) acquired on 13 , 24 March 2011 and 4 April 2011.
This automatic extraction method utilizes the characteristics of weak microwave reflectivity from the smooth surface (dark displayed).
The pink area shows estimated flooded area of March 13, the orange area indicates the estimated flooded area of March 24 and the red area indicates the estimated flooded area of April 4.

19. The estimated flooded area map (Aomori Pref. - Ibaraki Pref.)

The flooded areas were visually interpreted from before and after the earthquake satellite images, and overplayed on topographic maps.
We hope those maps would be useful for planning the reconstruction of damaged areas and recovery from the disaster.

*The interpreted area might be difference form the actual flooded area, since we have not conducted the field survey.

PASCO attempted the automatic extraction of flooded area caused by the tsunami using the information from the synthetic aperture radar satellite (TerraSAR-X) acquired on 13 , 15, and 16 March 2011. This automatic extraction method utilizes the characteristics of weak microwave reflectivity from the smooth surface (dark displayed).
The pink area shows estimated flooded area of March 13, the yellow area indicates the estimated flooded area of March 15, and the pea green area indicates the estimated flooded area of March 16.
Comparison of temporal acquisitions shows the shrinking trend of the flooded area, but still it is continuing in the wide range.

2. The area below 10m above sea level of the coastal Pacific Ocean north of Sendai

A huge tsunami occurred due to the Great East Japan Earthquake at 14:46 on March 11, 2011. Since topography was greatly affected due to tsunami inundation, PASCO extracted the area below altitude 10m. The damage caused by tsunami was very extensive. The maps are published separately as multiple sheets.
