US Geological Survey has revealed that the 11 March, 2011 earthquake that caused massive destruction, has also moved the Japanese
island by as much as 8 feet which according to them, is a reasonable number.
island by as much as 8 feet which according to them, is a reasonable number.The quake which resulted due to thrust faulting along the boundary of Pacific & North American Tectonic plates was big enough to slide the island by such a huge figure (compared to other numbers observed in such scenarios). The pacific plate is already sliding under the North American plate at a rate of 3.3inches/year but this quake moved the plates 96 inches in one jolt.
This shift is usually measured with the help of Global Positioning System (GPS) which can accurately point out locations and comparing the latest data with previous one, the extent to which the change happens can be determined
