Quake Watch 2013

reply to post by PuterMan


Oh yeah, I don't look at USGS much any more so haven't seen those plots for a long while.
So quite a shallow dive there, compared to the others like the Tonga zone which is supposedly 45 degrees to 600km (there is probably a technical term for that "dive' but my mind has gone blank)

Wadati–Benioff zone.

I'm so excited!
I was wilfing around on the site for our closest seismo,
at a college about 35 miles away, to see what the 8.3 looked like there.
Here it is here in PA:

rev.seis.sc.edu...

I found a bunch of stuff I didn't notice before!

This map shows the present large eqs, & significant past ones.
If you hover on a ring, it gives date, time & magnitude.
Click on it & you get the seismos from the event, location, depth...

rev.seis.sc.edu...

Click on the one in Calif, (they say 5.9), & it also gives past significant ones for that area!
And best of all, I can get my polar views with latitude & longitude grids!!!!!!!
Pfffttt!!! Take that USGS!!! You are rapidly being replaced!!!!

Maybe everyone has a link like this already.
But I'm such a noob I didn't!
I feel like Santa was here!!!

Not much Ocean to travel through, so maybe more vibes.
I recall the 7.9 in May 2006 in Tonga, was 2,400km from me but we felt the wobble, and vertigo if you like to call it that, no shaking or noise but it felt like the Planet had taken a hit. Can relate it to the Moscovites reports.

Good for you.
For the ones who just like Lists, this one gives 4.0+ Worldwide
www.iris.washington.edu...
there are a few missing though, like

2013-05-25 02:26:14, Mag 4.9, 49.51°N, 156.21°E, 63, Kuril Islands [gfz]

which was between Fiji and Macquarie timewise

That IRIS kind of matches LDEO's list

the best method is to shop around though


speaking of LDEO, they seem to be stuck on N.Cali 5.8, still haven't listed the 8.3 yet

This USGS (Useless) change has really mucked everyone up, including Live Earthquake Mashup

The Live Earthquake Mashup is currently out of order. I hope I can fix it next weekend. Please come back in a few days. As a quick workaround, you can load the feeds directly in Google Maps, alas without the Timeline and the additional information:

his feed from EMSC still works OK on the alternative Google Maps temp solution, with the details in the popups, but not for USGS. Must be trying to get at the newly formatted source data.

I should sell him some coloured icons

Hi WOQ. I knew of rev.seis but I am sure it was not a comprehensive as that so thanks for mentioning it again. I think it is good enough to be listed as a world wide earthquake source.

Have you seen this site: EarthquakeTrack.com ? You might like that one as well.

BTW: Can't remember who was moaning about not having a north pole view but rev.seis has that.

I should sell him my JSON reader. I knew they would dump the old data despite the fact that they assured me they would not. I am glad I switch over when I did.

BTW Muzzy that map of the Aleutian subduction you will not find on USGS - I don't go there either. I created that from ANSS data myself.

reply to post by aLLeKs

I was sitting in the kitchen and an empty milk package fell over. the scissors which are hanging on the wall were moving and the coffee was moving.

My parents said I am crazy, but now I found the reason. so apparently the quake was at 9:44 and I saw all the things at arround 10 + - 10 minutes... so should be possible with the wave travelling.

I am confused. The quake was at 05:44 UTC. As far as I am aware Germany is 2 hrs ahead in summer so that makes it 07:44 AM in Germany. Kamchatka, the peninsula, is I think on the ANAT time zone which is, like New Zealand UTC +12, but the sea around there is UTC +10 which is what USGS reported. Local reports from the land should be +12.

dreamfox reported the quake as 22:44

8.2
Sea of Okhotsk
2013-05-23 22:44:48-07:00619.0 km deep

That however was US west coast time if that is the case (not a useful time to post BTW. I venture to suggest that posts here should always be in UTC) which is maybe where the confusion arises?

Basically if you felt the world wobble at 09:44 in Germany, which would be 07:44 UTC, then it was not because of the Russian quake IMHO. Maybe your parents were right?

Maybe the ground was shaking as Angela Merkel's trucks rolled past bring in the Euros/Gold/Booty from the other EU countries, or perhaps she was stamping her foot at Germany losing the Eurovision song contest?

Just found a little update for you from a volcanologist re those California quakes

Earthquake Swarm Near Greenville in California

I’ve been getting a lot of questions about the current Greenville, California earthquake swarm. This is likely due to the fact that the swarm is in the vicinity of the Lassen Volcanic Center, which is ~50 km to the northwest of these earthquakes. Now, I don’t like to delve too much into earthquakes that aren’t volcanically-related here, but I thought I’d share some information on the earthquakes just to help with some of these questions.

First, these earthquakes have nothing to do with the Lassen Volcanic Center (LVC). They are centered much too far away to have any connection.............................................

Here you are. Have a listen to it instead. Taken from BORG on Iceland(BH2 channel 20 sps) Speeded up 400 times.

Magnitude 8.3 Sea of Okhotsk.mp3

It is zipped as we are not allowed to link to files that start playing immediately. T & C and all that.

WHOA, that's more eerie than the Tohoku recording It's like someone is rhythmically & slowly banging on a kettle drum. Thanks for digging it up, I'm going to leave it on repeat for a while

Unless the whole area is one giant super volcano....

Just sayin' !!

reply to post by Nyiah


I just realised that you are putting up weird American times as well. In the post refered you have a quake @21:55 Mag 6 which I have been trying to find.

I found it at last

gfzp,2013-05-21 01:55:09, 52.460, 160.440, 5.9, 34.0, Off E. Coast Of Kamchatka

emsc,2013-05-21 01:55:04, 52.440, 160.485, 6.0, 10.0, Off E. Coast Of Kamchatka

Could we all PLEASE use UTC or if posting times from some regional time zone perspective at least state that fact. Not blaming you folks, blaming Useless Seismicity Guessing Symposium for allowing quake listings in peoples local times. :shk:

A quake in New Zealand at 23:00 NZST should NOT get reported to a computer listing for someone in the States on the West coast as 04:00, or if it is the should say 04:00 PDT so that is clear. It should of course be reported as 11:00 UTC like EMSC and GFZ and everyone else in the world who publishes global listings. Never could get my head round Yellowstone listings in MDT but I excuse those as local/regional listings.

Puterman, Muzzy or anyone
Do you have any good Google Earth KML files for the New Madrid region?

Maybe my imagination is ramping up, but I got a alerted to these off my phone in the middle of the night and earlier today.



Admittedly it could be the lack of sleep, and while these are not big quakes the sudden clusters of them seem to suggest a fault line flexing.

Do you have any good Google Earth KML files for the New Madrid region?

What sort of KML files are you looking for? Historic, current, faults, etc???

Forgot to add: This poster of the theoretical Mag 7.7 on the 16 May 2011 in the NMSZ may help. You can take your pick which version you look at. (The only ones worth bothering with are the High Res and the PDF.)





I have found what appears to be a set of three KML files marking the main NMSZ fault. I will join it together into one file and get back to you if it is any good.

reply to post by PuterMan

I think its time to put an F in front of that USGS. (excuse the French)
Theoretical P wave Travel Times are gone again, and so is Phase Data on each event.
Still haven't fixed the TT calculator either.
grrr

edit on 25/5/2013 by PuterMan because: (no reason given)

Well any of those would help
In a perfect world I could get recent, current and historic in one fell swoop, but I'll take what I can get. I'll look at the theoretical one in a bit.
Thanks.

reply to post by Moshpet


I just added to my post above about the fault lines. I will dig up some historical and current data and create a KML of the whole lot.

reply to post by muzzy


Try the QVSData program. I can get phase data in that because it does not use the data page we normally get but searches the JSON data in the footer of the html page for the event. Therein you find references for all the various files available. I used that to grab the phase data.

On a USGS quake right click and select phase data. What you get is the listing sorted by arrival and by station as in my blog posts. This only works for quakes up to 30 days old.

I wonder if a Bipolar earthquake can happen these days.

Hmm, well the clusters from this past week & today pretty much match up to the historical data of the 1800's- onward.
Including the cluster above Littlerock, AZ. The cluster above/near Jonesborough, AZ is a bit out of place though. Likely not enough to fret over but worth keeping an eye on I reckon.
