Tokyo Rocked by 4.7 Magnitude Earthquake

An earthquake with a preliminary magnitude of 4.7 shook buildings in Tokyo on Wednesday, Japan’s Meteorological Agency said, but no tsunami warning was issued and there were no immediate reports of damage. Earthquakes are common in Japan, one of the world’s most seismically active areas. Japan accounts for about 20 percent of the world’s earthquakes of magnitude 6 or greater.
