The geological structure of the Kanto region, which includes Tokyo, is complex with the interaction of the Philippine, Pacific and Eurasian plates, but Shinji Toda argued the portion of a plate believed to be part of the Philippine plate was indeed an independent tectonic plate, Kyodo News Agency said.
Toda, chief researcher at the Active Fault Research Center of the National Institute of Advanced Industrial Science and Technology, said he analyzed data on 150,000 quakes with magnitudes above 2.0 between 1979 and 2004 in the Kanto region, Kyodo said.
