Yeah MoorfNZ caught that one, page 91 and I added 3 aftershocks page 92.

Got lost in the mire of Japan and Nevada. Hard to keep track when there are 4 pages of replies per day

Been 4 more aftershocks.

Interactive Te Uri Quake Map

Just slightly smaller than the Waiau River Valley one up near Wairoa, Hawkes Bay July 11 and the one near Kaituna, Wairarapa Nov 28 last year, aftershocks went on for weeks from both.

Guess where.....

Right on the "Cascadia Fault Zone"...

***ATS Members****
Keep close eye on the fault zone

Something tells me that this one is significant....

I agree that we should be watching the Cascadia......

We just had another 5.8 +/- The whole plate is unstable....

For those that doubted that 7.1 in Japan was a new source, and not really an aftershock of the 9+, I am ready to rumble.

It IS a new source:

A 5.4 magnitude quake off the coast of Chile, 23 minutes ago.

Been sorta quiet for awhile (other than Japan - which is sorta too quiet to) - I don't like when it's quiet as it usually is followed by something big

Puterman, would you do me a favor and have a listen to This . It has an odd signature and thought a listen might enlighten me.

Where did you get the maps off JMA ?

My opinion is that the 7.1 is an aftershock in the sense that the scale of the 9.0 event was such that the entire east coast of Japan has been "loosened" up and old faults have been reactivated.

The question that arises and defines whether it is an aftershock or not is "without the 9.0 would ths 7.1 have gone off anyway?"

Having said that I'd go so far as to say that geographically this is a seperate event, tiggered by the 9.0, in manner simialr to the Darfield Chrsitchurch 7.1 and the Lyttelton/Port Hills 6.3 (where they are still debating whether the 6.3 was a seperate event or an aftershock). That was 6 months between them.

I turned on EQ-3d & noticed that the was a fairly active swarm going on at the Caribbean Plate near / off the north shore of Anegda (Virgin Islands area). Just by eyeballing it it looks like 50+ quakes, the highest being a 5.1 . Most of the quake around it seem to be todays.

I would greatly appreciate anybody that can verify the following simple information. It is important to me to get the facts.


On April 11th, I recently checked the USGS website for the first time this year, to see a list of earthquake activity in the last 30 days.

When I checked the the USGS link that provides the data for the "Past 8-30 days"(world-wide) it WRONGLY SHOWED data for March 9th through to March 31st, when it should have instead displayed data from March 13th to April 4th.

The data for April 1st/2nd/3rd/and 4th, were not available on either the "Past 7 days (M5+)" link NOR on the "Past 8-30 days" link when I checked late night April 11th.

Did anybody else notice that on April 11th, and perhaps April 9th to April 11th, that the "the Past 8-30 days" link was NOT properly updated? and if so, is it common for that USGS link to show the wrong range of dates(8-30) for several days at a time?

Thanks in advance.

what is going on in Nevada??

Wednesday April 13 2011, 22:10:07 UTC 17 minutes ago Nevada 4.5 0.0 Detail

and the depth is 0...does that mean it could be military manuevers (bombing range)?

link quakes.globalincidentmap.com...

now thay are reporting depth at 13 km.

reply to post by megabogie


Yep..I see the Nevada 4.4 /4.5 quake on USGS

This makes their 2nd mag 4 + this week....

Is the San Andreas fault line giving foreshocks?

reply to post by ButterCookie


I noticed on Sunday it suddenly got very active there in Nevada. I watch the global incident map and never saw so many quakes there in such a short time. Let's hope you're not right about the fault...but it's getting me kinda nervous

reply to post by megabogie


Okay....Northern Cali just had a 2.3 minutes after the Nevada...

Gonna be watching this area's activity tonight

reply to post by ButterCookie


I hate being so paranoid about these things...let's hope it's just normal activity for california and a fluke for Nevada
