Over FIFTY earthquakes in the last several hours in Alaska and still counting

There has just been a Mag 7.5 there now.

Please, do you have another link for the previous mentioned info?

I would like to read it and check if there are Tsunami warnings, but with no success.

Thank you.


P.S.: there must be a broken link or the USGS is changing details...

Has it been reviewed and changed to a magnitude 6.2?

Ok.

I found the answer to my question on the Quake thread written by Val.

It has been downgraded to a 6.2

Yes but it has already been down graded

Man............. I wish I had more time to post some things referencing these quakes.

I have to stay on track with my road trip for now. Bummer............ I'll be back to play a bit in a few days.

Crap! Got to go. Catch ya all later!

Look at this list of quakes for today:

I wrote more about this on the Quake Watch 2006 forum. I'm still seeing a 7.47.

I see the same here Dearwife.

I think that we can certainly call this another significant swarm!

The magnitudes are really something.

I am going to check out what you have at the other forum Dearwife.

I have a lot of things to check out and anxious to share them here. Somewhat settled in for the evening. Had some problems with the RV, so trying to relax a bit before I dive into it.

I am surprised there is not a few more posts here for this activity.

Where is everyone?

Hey! What about that full moon guys and gals? Some timing.........


[edit on 7/9/2006 by Fringefellow]

Crap, I just can not do this tonight. Be back tomorrow with some goodies to talk about!

Hellmutt I just caught your signiture!!!

How appropriate for this thread....

Every time there is a quake for either the Explorer, Juan de Fuca, or Gorda plates it is relevant to my observing the coastal PNW.

This 3.5 is on the Northern Explorer Plate , important because as the quakes build off the coast of BC and the coast of Northern California’s Gorda plate, it may be contributing to a build up in pressure on the Juan de Fuca.

So this 3.5 will be another to add to the recent activity for the Gorda Plate.

Not much of a history for this region as well. 65.807 -169.641

These below are just the 4.0+ quakes over the last two days. It does not include about another 30 or so smaller ones.

It is really something to compare the history of this area from 1973 to present.

There have already been in the last two days about half as many as have been recorded as a whole since 1973!

Seems to be a lot of activity at about the 50km depth as an average since this recent swarm began.

Pacific Northwest Coastal Stations and map.

July 9 and 10

You would not see it unless you looked at these every day, but this OFR Station is different today in that it shows a lot of noise. Nothing indicating any tremors or anything, just odd….

Same thing for this WISH Station

Same for this HEBO Station. Nothing exciting though.

Again though, these following stations starting with the TOLO Station for Central Oregon Coastal shows significant tremors and many suspect EM signals.

The rest of the PNW coastal states are quiet as well as all stations inland.

I am noticing some other forums suggesting a significant earthquake likely during the next seven days or so. Some are suggesting 8 and 9+ quakes offshore for the PNW coastal regions.

Hmmmm........

Okedokey, enough from me today. Still on the road, and need to get some sleep. Otherwise I would be up till the early morning hours going over earthchange/earthquake topics.

Later........

How big was the largest earthquake in Alaska?

The largest earthquake recorded in Alaska was a M9.2 that occurred on March 27, 1964 in the Prince William Sound. This was the 2nd largest earthquake ever recorded in world history. The energy released in this earthquake was equivalent to approximately 4 trillion pounds of explosive. The motions on the fault lasted for 4 minutes, rupturing an area about 800 kilometers long and 250 kilometers wide. The average movement on the fault was about 9 meters.

On average, Alaska can expect:


1 M > 8 every 13 years
1 M = 7-8 every year
5 M = 6-7 every year
20 M = 5-6 every year
90 M = 4-5 every year
400 M = 3-4 every year
2100 M = 2-3 every year

I will bet that they have exceeded a couple of these average categories this year. I think perhaps both the M6+ to7.0 as well as the M5+ to 6.

I would have to go back to look, but pretty sure that this swarm has lasted longer and had more 4.0and 5.0+ quakes in a shorter period of time than the first swarm that happened at Rat/Fox Island.

Of course these do not include all the smaller 2.0+ and 3.0+ quakes for the day.

They are all at the same depth.

Need to check to see if I can find a little something more out about this area. This is not like the other areas. No little quakes and tremors in between. Each one of them are a real KABOOM!!
