Title: Quake-caused subsidence spreads
Source: NHK WORLD English-
Date: Dec. 17, 2012
The Environment Ministry says nearly 6,000 square kilometers of land across Japan have subsided by more than 2 centimeters in the last fiscal year. [...]
This level is judged to have a potential impact on buildings’ stability.
The ministry says Kesennuma in Miyagi Prefecture sank deepest by 73.8 centimeters, followed by Ichikawa in Chiba by 30.9 centimeters [Fukushima Prefecture NOT tested]
The ministry officials say the subsidence is attributable to last year’s March 11th earthquake. They have expressed concerns over the spread of subsidence and further damage to buildings.
