TOKYO -- Japanese scientists were warning Thursday that Tokyo could soon be hit by a massive earthquake, following a surge in seismic activity.
Seismologists at the University of Tokyo detected a huge increase in the number of small quakes in the tectonic plates below the capital.....And the scientists measuring the quakes did not rule out the possibility that a combination of earthquakes in two or more points in the earth's crust could unite -- doubling their destructive power.....The northeast of the country was devastated by a magnitude-9.1 quake in March, and some seismologists were calling on the government to revise its emergency planning, which is currently based on the assumption that any quake hitting Tokyo would have a maximum magnitude of 7.3.
"Because of the March 11 quake, the possibility of a big quake occurring in Tokyo has increased," according to Shinichi Sakai, assistant professor at the university's Earthquake Research Institute......"It is necessary to make preparations on the assumption that a big quake could come to Tokyo at any time and that the danger is greater than before."....
.....A multiple mega-earthquake could lead to the deaths of almost 25,000 people, according to a government study last year......Around 20,000 people were left missing or dead following the March earthquake and tsunam
