Quake Watch 2012

First, let's get our geography correct. It's not Manitoba. It was in Saskatchewan. Okay, all together now, say, Sackatchewan. Then say, Saskatoon, Sackatchewan. The capital of Saskatchewan is Regina.

I think is about the area and where is felt more,and...

hmmm, pretty large for zero depth... going to check out google earth to see whats there

reply to post by ericblair4891


they even drew a map of it on Google Maps, but obviously poor communication between departments

Never mind dear boy. Somewhere in the colonies anyway don'tcha know? I say, is it time to splice the mainbrace yet? Oh spiffing!! Big G and T for me old chap.

Nearest station on the phase data: DGMT.US.10.BHZ.2012.032

Other quakes there not being reported or not quakes??


ETA: I pulled the data file on that nearest station from 00:00 to 18:00. The other signatures are not quakes they are interference. The one the USGS says is a quake is a quake for sure ( or a small nuke? ). Very nice clear sound and p/s wave on the signal with 33.02 seconds difference over 297.7 km giving a travel speed of 9.015 km per second for the P wave. My manual read is only slightly out from theirs (0.12 seconds) but then I don't have the advantage of their equipment.

actually I don't know why I posted this..

reply to post by Hellas


'cos you thought it said 7.2 perhaps. Been at the G & T have you?

Maybe because you thought Hawaii may sink because of it?

No, I don't know why you posted it either

I was looking for volcano activity around the globe, then I saw this one and I must have confused it with a big one i guess. When I saw it posted i thought, wait something's wrong here

Earthquake Analysis 2011 now available. I have done a graph for each of the 50 Flinn-Engdahl regions. 40 regions have seen a decrease in activity by comparison to the average for the decade and 9 have seen an increase.

I am not posting it on ATS because it is too big, too complex for the available coding on ATS and has too many images and pages. I guess only people who visit this thread would be interested anyway.

Extremely comprehensive, thank you. Might take a while to process it all.

Nice one USGS!


Another error I think. Magnitude 6.5 OFFSHORE VERACRUZ, MEXICO

EMSC and the original say 4.6
www.emsc-csem.org...

They now have it on the 8-30 day listing at 6.5
neic.usgs.gov...


And another.

Originally 4.7. Still in EMSC as 4.7
www.emsc-csem.org...

Now on the 8-30 days as 6.0

reply to post by PuterMan


Which is the wrong one now? And how can they be that different?

That 6.5 has to be an error for sure neic.usgs.gov...

here is SNZO for that date, there is nothing in the mag 6 range except the Puysegur, NZ 5.8 one later on.
6's always show on LISS SNZO no matter what part of the Globe they are in, so a 6.5 would be at least as big a trace as the Puysegur one, if perhaps a bit more elongated.
I calculate that the arrival time of a 6.5 based on the time, depth and co-ordinates from that page would be
P wave 20:13:58
S wave 20:43:58
calculator
I see nothing on that line at all, a 4.4 in Mexico however would not show either at that distance

I haven't looked at the other 2 in detail yet but there is nothing on SNZO for the 16th except South Sandwich islands 6.6, 6.2 (supposed Nicuargua 6.0)

Good catch Puterman , definitely something amiss.at USGS
Worthwhile keeping those old LISS graphs eh.

wot your done already?
Great stuff.
Of course I went straight to New Zealand to have a look.

I'll have to take a look at the ANSS data for 2004 whic jumped out at me on the graph.
on my old Historic NZ Quakes blog I have for 2004 UTC

In 2004 there were;
4216 events 1.0 to 1.99 ML
10604 events 2.0 to 2.99 ML
2843 events 3.0 to 3.99 ML
267 events 4.0 to 4.99 ML
13 events 5.0 to 5.99 ML
1 event 7.1 ML (Puysegur Trench)

I lost the data for that but its easy enough go get a fresh csv download off Geonet, but the point is the difference between that and ANSS.
ANSS must have converted that 7.1 to something outrageously beyond 7.6 (what the 2009 Dusky Sound ended up as )

PM that is a Prelim report.

Even so, there is such a huge difference between the report and the actual magnitude, I mean- that's like just not right and not good. For a lot of reasons, and particularly for EMS crews and disaster planners.

This keeps up, and people are going to lose confidence in USGS. They need to DO something to fix this nonsense.

I'll bet an average mag guess taken between the regulars, and we'd report the things with more consistency.

:shk: They need to get it together, for sure.

PM that is a Prelim report.

As they all are even several years after the event! Example: earthquake.usgs.gov...

These were originally put out by USGS and EMSC at the current EMSC values. This is a computer glitch i think. I have notified them of all three.

The mag 6 values are the errors.
