Re: [Geology2] Another Quake, Tsunami Warning issued



There is always a difference..... after the significant quakes the various parties sit down and hash out a compromise magnitude that becomes the official figure. There is not need to bother with the smaller ones.

At least one more quake is indicated with figures all over the place.

Indonesia is going with 6.9 and the USGS is going with 6.3 and still another automatic computer has it at 6.2

I really want to know why there is such a big difference?

A tsunami warning is in effect.



By Associated Press,

TOKYO — A strong earthquake has jolted northeastern Japan and authorities have issued a warning of a possible tsunami.

The Japan Meteorological Agency says the earthquake with a preliminary magnitude of 7.3 struck in the Pacific Ocean off the coast of Miyagi prefecture at 5:18 p.m. (0818 GMT) Friday. The epicenter was 10 kilometers (6.2 miles) beneath the seabed.


The warning said the tsunami could be as high as 2 meters (2.19 yards).

Buildings in Tokyo swayed for at least several minutes.
