Tsunami warning center raises magnitude of Japan quake to 9.1

[ AD HAS BEEN REMOVED FROM THIS STORY ]

 

 

The Japan earthquake was the fourth most powerful ever recorded with a magnitude of 9.1, twice more powerful than the initial estimate of 8.9, Gerard Fryer, geophysicist of the Pacific Tsunami Warning Center, said this morning.

Three others that were more powerful since the late 1800s when seismometers started measuring ground motions were in 9.5 in Chile in 1960, 9.2 in Alaska in 1964 and 9.1 in Sumatra in 2004, according to Fryer.

The new magnitude was adjusted based on the impact of the quake  throughout the Pacific, he said.  "It fits all measurements, including in Hawaii," Fryer said.

The U.S. Geological Survey estimate of the quake’s magnitude is still 8.9.

It is not uncommon for scientists to estimate different magnitudes immediately after an earthquake.
