Wow.....

I wonder if this one will generate a Tsunami?

[commonguymd]

Readings from Utah - wow.

BTTT

[NautiNurse]

After a relatively quiet year--there were five Mag 7+ quakes in November, and now 2 Mag 8.1 in as many days.

EVALUATION

REVISED MAGNITUDE BASED ON ANALYSIS OF MANTLE WAVES. THIS EARTHQUAKE IS LOCATED OUTSIDE THE PACIFIC. NO DESTRUCTIVE TSUNAMI THREAT EXISTS FOR THE PACIFIC BASIN BASED ON HISTORICAL EARTHQUAKE AND TSUNAMI DATA.

THERE IS THE POSSIBILITY OF A TSUNAMI NEAR THE EPICENTER.

I suppose we are going to hear from the person that says major earthquakes ALWAYS occur during full moons, since we have a full moon tonite.

[F.J. Mitchell]

LOL! Earth quakes being caused by faults-having the fault that caused an 8.1 named after someone should be deemed an honor by that someone.

_Jim? He's busy on another thread.

[Quix]

I suppose.

When was the one between New Zealand and Antarctica--a day or two ago?

[Bahbah]

Wow, that gives one a perspective.

[bd476]

Surf's up again here on this thread. This is now an 8.5 quake.

[bd476]

Yep, it's pretty startling. And you and your neighbors have had a very, very rough year. Hope next year is much better.

Merry Christmas, NautiNurse!

[bd476]

Thank you and good catch, Boundless. That's a very significant jump in magnitude.

[bd476]

Thank you for the news link, Commonguymd.

[bd476]

Whew, Lokibob. That's a very shaky graph. Thanks for posting it.

[commonguymd]

This report seems to be one of the first reported. It was reported as 6.4 on the island.
