Readjustment of the cadastral map in the East Japan earthquake disaster area
Sekine, Ichizo & Masatake Nanjo
In the Great East Japan Earthquake of magnitude 9 that took place on March 11, 2011, the largest earthquake in Japanns recorded history, strong shaking continued for about 3 minutes and the ground rumbled as if it was being dislocated. The huge tsunami which is said to be once in 1,000 years caused the death and missing of a great number of people, while many towns along the coast were devastated and reduced to ruins instantly. In the inland areas also, buildings collapsed and the landslides or ground cracks resulted. As this earthquake caused the earthhs crust to move over 5 meters horizontally and the land boundaries became missing or dislocated, various cadastral measures need to be taken for restoration. In this paper, we report the current status of the disaster area and efforts being made towards the reconstruction from the standpoint of Land and House Investigators who are engaged in the onsite restoration operations as cadastral professionals.
