Dear All ,

Conflicting reports are being received from Japan Meteorological Agency & United States Geological Survey with respect to seismic technical information pertinent to the earthquake that rattled Tokyo city at 3.13pm Japan Standard Time on Wednesday, August 20, 2008.
According to the Japanese experts the magnitude is Mb 4.5 but USGS says it is Mb 4.7 having focal depth of 10 km. Not only this, JMA scientists say its epicentre is 50km (31 miles) northeast of the capital but USGS asserts it is located at 37.048°N, 139.792°E about 155 km (95 miles) N of Tokyo, so a difference indeed.

So far no damage has been reported.
