Quake Watch 2014

reply to post by radpetey


No I don't believe they do.

Only YMR is showing anything interesting and it looks more like snow blowers than harmonic tremor.

Reviewing data is very important, especially when you are following trends or compiling graphs.
I did it for a while on my NZ earthquakes blog a few years back, but it was too much work, especially when the Christchurch quakes hit, actually it might have been the 2009 Dusky Sound 7.6 that made me throw the files away.

But I've got back into it, partly with the help of QVS DataPro to get the Preliminary data, its faster.
Here is a prime example of what difference a review can make.
One event. Source: Geonet

ID: 2014p159748
Status: preliminary
Date/Time UTC: 01/03/2014 02:33:59
Latitude, Longitude: -36.51749, 178.80264
Magnitude: 3.59ML
Energy Released (TTNT): 3.6594
Depth: 125.9km
Location: Auckland-Coromandel-Whakatane Seamount

Ref: 2014p159748
Status: reviewed, Updated on: 05/03/2014 04:39:10
When: 01/03/2014 02:33:47 UTC (12 second difference)
Lat/Long: -35.6084 179.764 (different location)
Depth: 33 km (shallower)
Mag: 4.0942 ML (bigger)
No. of Phases used: 53
Location: Whangarei-Rumble3-Healy (now in a totally different GL Region)

now the most significant difference
Energy Released: 20.8789 tonnes of TNT

17.2 Tonnes of TNT makes a BIG difference in the energy released when building a monthly/yearly ER graph.
the difference of TTNTER, thats about a M4.04, on top of the M3.59 !!!!!

I did not think so at all.....some other fellow on another site was having a doomgasam about these seismos.

Thank you for responding!

Something is perking in Puerto Rico.

The 1918 Puerto Rico earthquake caused a tsunami so as long as people are prepared we hopefully won't see another Indonesia or Japan situation if a big one hits that trench. I don't know if they have some sort of a siren system. If they don't I think this should be a top priority.

The Midwest quakes are also worrying (Oklahoma). The repetitive 3.1's from California for months now seem weird (even for California), but it's difficult to know what to think about California so unless one of the experts draws attention I don't think much of it. I will say the August 2012 swarm in Southern Cali (over 100 in what I think was a day) still sticks with me as significant. I feel that from out frame of reference (in the past so isolated) it doesn't mean a lot - but in the long run (in hindsight) we might see it as a warning of something more.

That last statement is not based on anything scientific (from me) but rather it was so hugely unusual that it fits into other things going on over the past couple of years more than I believe we currently understand. Or...maybe it has been included in someone's analysis herein and I'm not aware of that.

The Oklahoma quakes are not in the least worrying, in the sense that the cause is unknown. Worrying indeed that they happen but......

The United States Geological Survey (USGS) issued a press release (Released: 3/6/2014 [US Date] 5:00:00 PM ) indicating that the magnitude 5.7 earthquake that struck Prague, Oklahoma in 2011 was unintentionally human-induced.

The Church is admitting that the disposal of waste water is the culprit.

The 5.7 magnitude quake in Prague followed an injection of waste-water approximately 650 feet away from the Wilzetta fault zone, a complex fault system about 124 miles in length. All three earthquakes exhibited a slip-strike motion, and did so at three different locations, indicating that three separate areas of the fault zone were activated.

blah blah blah etc

* I noticed on that interactive map from 04/2007 (7 days worth) the lack of earthquakes in the Hitachi Mountains (I don't know what their real name is, but they are just north of Hitachi (which is NE of Tokyo, on the east coast)), compared to recent times. The daily maps I'm doing on GSAIM have heaps of them in the NEID Preliminary data every day, and even on JMA Reviewed data there would be about a dozen per day average over 7 days in those mountains now, I wonder if those were "triggered" by the 11/2011 M9.0 Tohoku monster? and are ongoing since then?
Interesting.

yeah those mountains got wacked with a 5.6 and a 5.7 on the day of the 9.0, quite significant earthquakes in their own right, in fact those were the biggest quakes on land in the first 9 hours after the big one.
So the current activity could still be related to those, or any subsequent large quakes ( I haven't checked yet)

Just going over our most recent M6 event here on land in New Zealand 46 days afterwards.
Again REVIEW changes a lot of things;

Status: PRELIMINARY
Date/Time (UTC): 20/01/2014 02:52:00
Main shock
Lat: -40.6193 Long: 175.8499

What was really surprising initially was the lack of aftershocks for the first two hours and forty minutes, usually the big aftershocks hit within that time period.

Ha! on REVIEW an extra 78 (new) aftershocks in those 2:40 hrs, M2's,3's and 4's

3 HOURS PRELIMINARY
mag1= 2 , mag2= 7 , mag3= 0
mag4= 0 , mag5= 0 , mag6= 1

3 HOURS ON REVIEW
mag1= 3 , mag2= 62 , mag3= 20
mag4= 3 , mag5= 0 , mag6= 1
total= 89, total energy released= 33,466.911TTNT
goo.gl...

I finished the preliminary maps at 15 days, and that has changed a bit too, an extra 64 earthquakes, so some must have been deleted as well.
Quite likely those ones down near Castlepoint (string of M3's on the preliminary map below that are no longer on the reviewed map)
15 DAYS PRELIMINARY
mag1= 1192 , mag2= 508 , mag3= 65
mag4= 2 , mag5= 0 , mag6= 1

15 DAYS ON REVIEW
mag1= 1200 , mag2= 548 , mag3= 72
mag4= 11 , mag5= 0 , mag6= 1

so wheres it at right now?

Interest in the Eketahuna quake is low compared to some of the other big events I have tracked
Views - Page
23 - Eketahuna (8 on the EarthQuake Archives version)
42 - Dusky Sound
69 - Canterbury (13 on EQA)
70 - Cook Strait (12 on EQA)

I sometimes wonder if I go too overboard with these pages/maps?
None of those have anywhere near the readership of this one on EQA, which has only one map and one graph.
135 - Ölüdeniz Açiklari-Muğla, Turkey 6.0 Aftershocks. Must have been local interest, there was nothing really outstanding about the quake itself, could have been the page name?, Turks searching specifically for those words ........

even L’Aquila, Italy 06/04/2009, 6.3Mw and aftershocks page which is the most comprehensive page I have done yet, only has had 17 views

Maybe less is best?
Damn it I want to know for myself, thats why I bother doing them, one day someone will see the value of it.

Still no Bath's Law aftershock one magnitude less # than the main shock, biggest so far was a M4.8 on 21st Jan.
Maybe there is more in that Pa Valley Fault yet? looking at all those 2766 icons, thats a darn lot of settling!

You seem a little jaded that people do not read them. I thought I would input my view. I do not often go to those pages, but I certainly pay very close attention to your posts making conclusions from those pages.

Sort of like doing a 50 page report and 99% of people only read the 3 page executive summary, but, if I think the report is wrong I would read the whole thing. Your work is mostly flawless, so I am always happy and delighted with the executive summary.

Your work is brilliant and I admire your dedication Muzzy.

P

Thanks pheonix.
I only do those maps because you can't find them anywhere else.
If I was living on a farm on Pa Valley Rd for example (Eketahuna quake) I suppose I would check in every day to see where the aftershocks were at, otherwise its probably just curiosity that brings the readers.

P-waves are showing up fairly good from this one... at lots of stations... kinda a weird spot though.. guess well see what happens

weird spot in what way???
Mex January map show its quite an active area, other monthly maps for the area show the same

About 10.20 here Crescent City, shook our house real good. Guess there is no Tsunami watch for this one.

Just saw a bigger one pop up. Let's hope this is all there is.

Ok wait a minute - are these 3 different 6.ers now or are they just changing their mags. The tsunami warming page had it listed as two but USGS has it as one and another just came through.

Can someone explain why they have it listed as a 7 on the tsunami tab and then also list a 7 in Hawaii? Maybe this is what it is out at sea and comes in at a lesser magnitude inland?
