Japan's main island shifted by 2.4 meters according to USGS
The U.S. Geological Survey (USGS) says Japan's main island (Honshu, comprising ~60% of Japan's area and ~80% of its population) has moved about 8 feet (or 2.4 meters) during the tragic earthquake on 11 March 2011:
So 1:24,000 maps and bigger (1:10,000 etc) will have to be corrected.
If this is true, all the Japanese large scale maps will have to be updated. They say the human eye can distinguish objects on a map if their length is bigger than 0.1 mm, so in which scale the 2.4 meter shift is visible?
So 1:24,000 maps and bigger (1:10,000 etc) will have to be corrected.
It will also be interesting to see if this change is visible in the Google Maps satellite layer. I have made a screenshot of level 21 where the change should be visible within a few weeks or months, when Google updates its imagery:
Coordinates are: 35.6821332,139.752048
