The focus of any major earthquake that strikes beneath the Tokyo metropolitan area is likely to be shallower than previously thought, a government project team said Wednesday.
The edge between the ground plate and the Philippine Sea plate underneath Tokyo is 5 or 10 km shallower than earlier projections, which could lead to Tokyo suffering a quake with an intensity of 7, greater than previously anticipated, the team said.
The team of scientists from the University of Tokyo and other organizations determined the correct depth of the tectonic plate junction by using a new quake-observing technique. (Japan Times)
