Quake Watch 2014

a reply to: Lil Drummerboy

so in your opinion is all that Energy , kinetic, or ,,potential,,


potential being some outside tanfer of Enegry,, which then starts the conversion too Kinetic.

keeping in mind the age old trueism,, if it does not have too move, its not, going too.

ie: crustal upward displacement,,of such a large area.

just curiuos,,

I did notice the double tap!
Thank you for posting additional info and screenshots/images

What usually happens with a bigger quake is that the Tsunami warning centre entry (PT network) which occurs first hangs around after the US network entry giving two for a time in the system. The PT entry then gets removed.

a reply to: PuterMan

Now that explains the double tap

Oklahoma seems to be experiencing another uptick in activity. Image from USGS showing mag 2.5 and higher over the past 7 days.


I wonder how long this will go on? Injection of fluids may have started this, but it almost seems like something else, tectonic in nature, has been activated. I've no evidence for this thought, just musing.

Anybody know where to find a long-term catalog of Icelandic earthquakes, that use IMO or Icelandic Institute of Earth Sciences data? All I can find is the catalog that ends in 1990.

I've about given up trying to understand the IMO's methodology for assigning magnitudes. They are all over the place.

Take the most recent Mag 5.2 found here, for instance.

This is how it looked on the BORG station in GEE. (I monitor this station because it is the nearest publicaly available.)

I've been watching these on and off for the past few weeks, so when I saw this one, I thought Mag 4.2-4.4. It definitely wasn't a Mag 5+.
The other reporting agencies saw it this way, too:
EMSC Mag 4.2 mb
GFZ Potsdam Mag 4.2
CEA France Mag 4.3 mb

Then IMO posts Mag 5.2. Huh?
I get it, they know the local geology better than anyone.
There must be something causing attenuation of the waves between Barðarbunga and 215kms west to the BORG seismometer.

So I looked at a couple different days of the BORG station in IRIS, all set to the same scale. (click images for full-sized versions)
Yesterday's plot:

Borg station yesterday--scaled

Today's plot:
II.BORG.10.BHZ

This shows a mag 5.4 from 7 September 2014. compare it to yesterdays' 5.4: IRIS day 250, station BORG

The magnitudes awarded, don't seem to match amplitudes from day to day, when using the same scale.
Unless, the less than 10 km distance between hypocenters makes that big of a difference? All of the depths are within 4 kms of each other.

I'm just wondering if the details posted on their 48 hr list are later reviewed/revised and published in a catalog somewhere, possibly with magnitude type and focal mechanisms.

hraun.vedur.is...
once you get to the year/week/map you want click on [Skjálftalisti] that will give you the list
vika means week, they seem to do the data fortnightly

looks like this
Nr Dags. Timi Breidd Lengd Dypi M ML
1 20080225 011857.993 65.04793 -16.07531 13.161 0.37 0.41

which is
Number Day Time Latitude Longitude Depth M (Mw?) ML
read date/time like this
20080225 011857.993
2008/02/25 01:18:57.993
25th Feb 2008 1:18:57 a.m.

M readings tend to be bigger than ML, thats the column you will find the M5's
I got confused about that using ML for 3 years and missing all the M5's that the likes of GFZ and EMSC were showing, it came to light during the Bardarbunga-Holuhraun series the last 31 days.


edit:
that 5.2 (if it is the same one) lists as
Number Day Time Latitude Longitude Depth M (Mw?) ML
349, 2014/09/17, 18:09:52.856, 64.61878, -17.38981, 5.883km, 5.15M, 3.45ML

3.45ML conversion by EMSC is ???

bit of a disturbance the last few days down south Solander Is. region 4 x 4.5-4.9's

goo.gl...

has been really quiet here in NZ for the last month, nothing much of any decent size, been concentrating on Bardarbunga over on Volcano Watch 2014

Thank you! Thank you!

Muzzy, you are the absolute best.

a reply to: Olivine

no problem
takes a bit of navigating, too bad they didn't have a complete list of the whole lot in one file.There must be 20 years worth of data there, that would be approx. over half a million earthquakes based on an average ( 2014) of 2350 a month!!!!

couple of 4's not too far from us early this morning, fairly deep, didn't feel them

In my experience BORG is always under par. It is very bad at picking up teleseisms as well.

There must be something causing attenuation of the waves between Barðarbunga and 215kms west to the BORG seismometer.

I believe that would be the mid Atlantic ridge! (If my memory is right without looking at the map).

I'm just wondering if the details posted on their 48 hr list are later reviewed/revised and published in a catalog somewhere

And in addition to what Muzzy told you, you may also not be aware that the Pro version of QVSData can download those direct from the catalogue (if that bit is still working - I have not done it for a while)

I was reading EMSC felt reports, a few of the locals getting upset,
one guy ( I presume its a guy) in Aigio 39 km E from epicenter getting real pissed off about it
comments on the M4.7
comments on the M4.0

a reply to: PuterMan

yes it is still working I just ran part of 1995 off it
lucky I read this, I forgot all about that option, I was wondering where I got so many 2013 text files for Iceland, that is where!
It looks jumbled when you download it but if you copy and paste it into Excel its makes sense, in rows.

I should have given you credit for pointing me to the Iceland catalog as well, was a few years ago now I believe

's OK. I wasn't looking for recognition.

one guy ( I presume its a guy) in Aigio 39 km E from epicenter getting real pissed off about it

He should complain to his MEP. I am sure the EU has regulated earthquakes. They seem to regulate everything else.

European Union. Regulation of potatoes: Potatoes sold in shops shall be of even shape and between 40mm and 80mm in diameter.

European Union. Regulation of Earthquakes: Earthquakes occurring in the EU economic zone shall be at a consistent depth of 10km and between Magnitude 1.0 and 4.0 on the Richter scale. Severe penalties including but not limited to fines and imprisonment shall be applicable where authorities have permitted earthquakes outside this range or have failed to notify a region that such an earthquake is scheduled to occur. (L'Aquila geologists please note)


Anyone noticed that the Mag 7 Marianas is now a Mag 6.7?

This woke me up!
Cat was on the bed and jumped down and out the cat door like a flash then the shaking started, first time he has reacted to one. His twin brother never moved, may have lifted his head, don't know it was dark.
He was a bit spooked all day yesterday too, we thought it was the weather, been a real wintery storm on, high winds, rain, small hail, very cold for this time of year, was 4C yesterday at one point in the middle of the day.

been quite a while since the last one (on land), last one was 06/06/2014 03:46:54 SW of Mt Ruapehu 103.1 km deep


edit:
was this yesterday early morning NZST too, down south of NZ

seems NZ has kicked back into life after quite a long period of quiet



edit2:
those 4 quakes pumped up the total energy released from 2,191.164TTNT to 8,103.119TTNT in the snap of the fingers geologically speaking
still quite low for the month though, Kermadecs have been quiet too.

Now that Scotland is back in the United Kingdom (was close) they should all 3 get out of the EU, I'm sure life was better before they joined it.

I only seen that Marianas as a 7 on USGS, all the rest had 6ish, so I waited before (not) putting it up on the World 7's
