The strongest quake felt in Tokyo in 10 years has brought back memories of the Great East Japan Earthquake and reignited concerns over the seismic risk in the world¡¯s most populous metropolitan area.

Over the years, a government panel has compiled various scenarios for future earthquakes in Japan, including the possibility of a magnitude 7 quake directly under the capital. But the Meteorological Agency was quick to dispel speculation that Thursday¡¯s tremor ¡ª a magnitude 5.9 earthquake that shook Tokyo late that night ¡ª could be a foreshock for a larger quake.

¡°At this time, we do not believe there is a connection between yesterday¡¯s tremor and the earthquake predicted to occur under Tokyo some time in the future,¡± agency official Shinya Tsukada said during a news conference early Friday.
