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.

From past experience, the mainstream media will be filtering in new reports for the next 24 hours.

Sure is. It's now been revised upward from 8.1 to 8.5. Big boom.

If they called it anything but "great" it would be more fitting. Monstrous, Extra large... something like that. :)

How would you rate the increase in echos? X's or in %?

Exactly, it's a monster quake. There's nothing "great" about it. :)

Can I please ask the obvious dumb question?..How do you have two quakes that huge and NOT generate a tsunami? I understand they are a "pulse" in the water near the souce..and spread out..and rise only as they approach land..a shallow bottom...but..where are they?

The Earth is a dynamic place, that's for sure.

A witness also told the radio from Sigli, in Aceh's Pidie district, the quake caused the dome of the main mosque there to collapse. The witness said there were no reports of any casualties.
Have prayed God would leave authentic churches standing and crash all the idol focused temples in quakes in Asia--whatever His Spirit's wisdom dictated in each situation but to make increasingly and abundantly clear where HE STOOD on such matters.
I don't know when I'll start to see answers to such prayers. But I believe I will in my lifetime. So this was a bit startling to read.

Good question and you partially answered it, Ken. A local tsunami close to the epicenter is possible but not guaranteed within the next several hours.
The previous 8.1 quake near Macquerie Island two days ago generated a tiny tsunami - 20 cm. in height. The most common and typical tsunamis cause shoreline damage from the increased volume of water inundating the shoreline rather than a large wave breaking over treetops.

The 8.1 day before yesterday and this one sounds like a plate shift. As long as they're deep (sea floor, which they seem to be), seismic sea wave unlikely.

We felt that one here in Arizona, too... but it was on the desert side of the San Bernardino Mountain range ...

This is a terrible thing to say -- but since those islands have become sooooooo Islamic how appropriate for a wakeup call on Christmas Day --
