Quake Watch 2012

Of course originally that was a 6.4 Mw and they downgraded it. See details here

Maybe the seismo is showing the original 6.4 ? (Please no one take that comment as serious)

The November one was 50km deep and the latest one was 85km deep so maybe that accounts for some of it. Also oc course this latest one is not 7 days old yet so it will probably be downgraded to 5.9 Mw.

can 60km really make that much difference in the size of the trace?

114 km by the way not 60



The latest one does not look so small in BUD: RABL.AU..BHZ.2012.097

Thanks for having a look.
The 60km I was referring to was the depth, I got that off NEIC for the Nov one, but if you are saying it was 50km then there is even less difference and the traces should be about the same,
And that latest one is closer to SNZO (something I didn't measure) so it should be bigger, given the latest one is recorded as 6.2 and the Nov one was 6.1.
I don't get it.
Like you say it may go down later.
I never looked at the LISS Rabaul at the time either, gone now.

still if you build a reservoir right on a fault line (Northern Ohariu Fault) in the Tararua Mountain Ranges it should be expected to withstand a Mag 6 at least, been there since the 1940's, I put a new roof on the Turbine Building back in 1989, still holding out

Could there possibly be a 5.0 or larger event inbound for California up to Oregon?

Seems like a lot of spread out tremors in those areas everytime I've gone to the global incident map as of late. With how quiet things have been I just feel the presence of something lurking, ready to blast off when we least expect it. No jinx please Sure has been quiet, though.

Just a "feeling"

Whatcha feeling Berk?

I have been away for awhile and catching up.
Has there been an increase in small quakes in the area,maybe some ground movement?

I have been "feeling" it all day myself.

reply to post by berkeleygal

good spotting, thats what they call a Mogi (doughnut hypothesis)
Said to occur in Alaska too, over a long period of time though.
Time will tell.
Expecting a 5+ any day now for NZ too.

With how quiet things have been

Never seen anything like it recently. Between Midnight and 10:30 UTC just 4 quakes worldwide above Mag 3.5? Nuts.

There are only 58 of Mag 1.0+

I thought that related to larger quakes over decades not small one over a few days. There are many 'circles' of quakes, not least of which is the huge one often seen encompassing Yellowstone and Cascadia and is centred approximately on Malheur Lake.

The other problem with the Mogi hypothesis is that as far as Tokai is concerned, for which it was developed, it has not happened yet. Not sure how many decades on needs to wait but as a prediction method, which is what it is, it seems way to inaccurate and woolly to be of any use.

Can someone tell me why the USGS map just changed? I went to check it today, like I do evevryday, and it looks like a dumbed-down version replaced what was there. I saw the other version as more detailed and informative, this map today looks like something you would present to a third grade class. Then maybe I'm just grumpy cause they changed what I was familiar with .

But seriously, does anybody know?

Katla 2.8 ?
en.vedur.is...

I noticed the map changed this morning. You can zoom in, make adjustments, etc. You can't take in as much at a glance.

jeez!

why fix something that ain't broke?

I DO NOT like the new layout at USGS

you reading this USGS?

reply to post by berkeleygal

I don't like it either. If you look down on the right lower part of page it gives you the option to view the old version.

I would like to revise my first comment. I don't like the map, but I do like that there is more information there on the page instead of having to go to other pages to get further information.

What map are you's refering to?
If you mean the "Real Time Maps" off Latest Earthquakes in the World - Past 7 days
which is here , didn't you get the memo?, its been trialed for quite a few months on beta version.
Once you get the hang of it you will find that its far superior to the old World Map, lots of options of how to set it, and off course the list changes with where you look at.
In fact I already forget what the old map looked like, was it that one with hundreds of squares all on top of each other and you couldn't tell what was where?
Only criticism I have is the backgrounds aren't very precise, Google Maps/Satellite/Terrain/Hybrid would have been better.

I guess if you are using DialUp it might be slow?

The 8-30 days list is gone now too. Now just set the slider on "Earthquake Age" to 30, and get the list and map

Probably will have teething trouble with it, Puterman already mentioned the updating/changing details hasn't been consistant, but with the 8-30 List gone now there is nothing to compare with.

Yeah I read some of the links off the Mogi Wiki Link, basically its BS

reply to post by PuterMan


You must have just been looking at USGS?

Reference 3687560
Depth (km) 115.9783
Magnitude 4.628
Date (UTC) 2012-04-09T06:48:09.445Z
NW of Te Anau, NZ

or do you mean the day before?

The 4th... one 5.5
The 5th... no 5.0 or greater, infact only three 4.5+ quakes
The 6th... the 6.2 in PNG and 5.5 in Indonesia
The 7th... barely globally, a 5.2, 5.0 and 5.8
The 8th... heaps of 2-4.5 mags and just one 5 mag, the 5.4
The 9th... 4 hours to go 'til the 10th and we've only had 4 quakes over a 4.5, no 5s.

What gives, Earth?

Don't get me wrong, I enjoy the quiet, the no lives at risk, but doesn't it just seem like she's either napping the *Spring away, or just severely churning at the stomach.

Is there anything else other than USGS

Actually if I turn on GeoNet and JMO (but not EMSC) I get this

That is still only 5 above the Mag 4 mark in the last 21 hours.
