LOL! Indeed. Imagine that here... no please - forget I said that.

Merry Christmas! Hope all is well. We're freezing here - are you getting any of these chilly Santa Ana winds there?

That would qualify as the 'understatement of the day'.

I've felt a 7. I'm in Las Vegas and that thing went off in So Cal. And I mean to tell ya - we FELT it! Hanging speakers whacking the wall, water sloshing out of the pool, etc.

Have you ever seen / read the first hand accounts of the big one in Alaska? Ground in continuous motion for 4 - 5 minutes, etc.?

I could not imagine being really close to something of that immense power. Hard for the mind to comprehend something like that, ya know?

Well, Al Gore was planning a trip to Victoria, Texas to make a not-so-white Christmas Day speech to blame the general lack of snow cover on President Bush's global-warming policies. He missed that speech and an earlier speaking engagement in Cincinnati (to blame the general lack of blizzards on the President). He was unable to extricate his car from his Tennessee driveway--even with the help of his entire Secret Service detail--because of excessive ice accretion, which he would have blamed on the President's global-warming policy if the storm had not knocked out telephone service to his estate.

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.

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.

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!

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

It's now been revised from an earlier reading of 8.1 to 8.5. Local tsunamis are possible, but far ranging tsunamis are not predicted.

Look back at the seismometer chart, it is updating in a real near time basis. the earth continues to ring even an hour after the event. I have not seen this many echos on an EQ.

Yeah, well I assume you're kidding but some of us in Southern California have seen an increase in large quakes during Santa Ana conditions. It may be perceptual.
