USGS updated again...to 8.9 now....wow!!!

[nhoward14]

Wow! That is an 8x power increase from the first reported level of 8.1.

[Strategerist]

Yep....wow is right. Like I said these magnitudes, especially for huge quakes, will be repeatedly revised.

Magnitude 8.9 - OFF THE WEST COAST OF NORTHERN SUMATRA

If that magnitude holds up it's now the 5th largest earthquake since 1900.

[Quix]

WOW.

Isn't each 0.1 greater = 10 X the energy?
