Morning Hellas....you OK?

Yes, thanks for asking. I didn't feel the ones near Crete this time. It is kinda strange thought.. 4 different spots were "hit" in just 24 hours in Greece.

Guess we'll have to wait for "Da Boyz" to get on here and tell us whether there is any link to Santorini/fault lines etc...from what I can see that fault line was quite active going all the way up through Turkey and Iran.

Stating the obvious....stay safe!

The ones in Crete could be.. the other ones not so much.

This is an oddly placed earthquake.

Is that normal for Greece?

Just wondering

I am assuming the black lines are fault lines? If they are can I assume what I posted to Hellas earlier today is correct then....we've been waiting for one of 'Da Boyz' to come in!

Not that many 4's in a day and a half no

reply to post by angelchemuel

yep, if you use the interactive map and click on a line somewhere it should popup a tag with the fault type.
Its just the one UGS use on their KML, I took the colours out because it was too confusing beside the coloured icons and roads on the maps.
No obvious trend to the sequence though, goes from the subduction zone at 1. up to the Gulf of Corinth west of Crete at 2., back to the SZ at 3., over to Karpathos east of Crete at 4., back to the Gulf of Corinth at 5. and ends in the Ioannina mountains in the north west at 6.
Looks like the whole Aegean (Hellenic) Plate went south a bit more than the 0.1mm per day allowed (37mm/year divided by 365 days)
usgs Greece summary
or maybe 0.1mm movement is enough to trigger a Mag 4

Not quite as rare as hen's teeth but getting on that way. I only have the 13 months of Canadian data so far but that does show a mag 2.0 ML in the region back in Feb of this year.



I was also quite interested to note that Canada extends it's watch right out to the MAR which is something I did not realise.

There have been 3 recorded in the Atlantic in the past 7 days. Note the difference in magnitude for the Canadian version. 5.6 ML to USGS 4.8 mb. Very approximately that is 0.4 Mw difference and 0.4 is 4 times stronger.



The Canadian 3.9 is MN - not sure what that is yet as a scale - and the USGS is 3.9 mbLg.

Or maybe 60 days of tension (6mm) is enough, or 120 days (12mm) etc etc. I don't think the stress for a quake builds in one day.

Lots of interesting movements there. GE shows a resultant of 9mm NNE which I find very curious. The Aegean plate is moving SW at variously between 30 and 37 mm depending on the source you look at and the African plate is moving NNE at 40mm and subducting, and the Anatolian plate and Arabic plates are pushing round.

But the statement on the map you referenced say "vitesse par rapport a L'Afrique" which is "speed compared to Africa" so is this saying Africa is being considered as static on that map? If subduction is taking place then the down moving plate has no effect on the plate above other than to slow it down a bit. All of this depends entirely upon the datum point for the GPS and without that you have no idea. Is the Aegean plate is moving at 37mm/yr relative to Africa as the datum, or is the datum the other side of the Gulf Of Corinth?

Of course according to some 'scientists' Europe is starting to slide under Africa, despite any evidence to support this and plenty to support the other. They even suggested that this would lead to more Med tsunamis and OMG we need an early warning system!

Plate tectonics is not a simple subject. It is nothing like as simple as the maps would suggest and I don't think we know even a small percentage of what actually happens (the geologists will of course tell you otherwise - they have to it is their jobs on the line). It is not even a subject upon which there is complete agreement and several different theories exist, all with their problems.

Would 7,000,000 cubic kilometres (very very approximately) moving a few millimetres set up stresses over a shortish period of time? I guess it would. Is that 21,000,000,000,000,000 tonnes @ a density of 3 tonnes/cu mtr or have I got some zeros in the wrong place? I think in the American method that is 21 quadrillion tons floating about the Aegean. Don't get your finger wedged in the gap!

A seismologist here said that a "big one" is long due.

I did not know their coverage was that extensive either. Thank you so much for the heads up.

Concerning USGS, I get the feeling they don't put much value in locating and listing moderate sized earthquakes from the mid-oceanic ridges in the Atlantic or Pacific.
Personally, I feel the more complete (and reasonably accurate) the data, the better our understanding of the timing and nature of the processes at work will be.

September 26 2012, the day of atonement, is the next 188 day earthquake cycle. It's also the closest approach of nibiru to earth according to John Moore. I'm thinking it will be a Canary Islands event.

There is no such thing as 188-day earthquake cycle. There is no proof of strong earthquakes happen between every 188 days. Its just viral marketing campaign selling the dvd. Its pretty genius idea, on average, major earthquake happen every 18 days, and time window for this 188 days cycle could be +/- 1 day, so changes are pretty good that strong earthquake falls on these 3 days. This guy is probably very rich after people buying his nonsense dvd.

Hello earthmoney123 and welcome to ATS and in particular to Quake Watch.

Here you will find some of the best information about earthquakes on the Internet. Why do I say that? Because the members who frequent this thread, and those who lurk and occasionally stick their heads up into the firing line on the whole produce excellent work that is based on facts.

You will find some of the alternative geophysical theories on this thread: Geophysics which is hosted by Zenius who you will also see on this thread.

Anything of a speculative nature to do with Yellowstone / Fracking / Arkansas / Bird Deaths / Hudson Bay / Life / Death / Resurrection / the Economy / Politics / Religion etc you can post on the thread hosted by Robin Marks/Eric Blair: Robinesque Ruminations

Volcano stuff you will find on Volcano Watch and last but by no means least the giant Yellowstone thread is a BIG read all about the Park that has passed page 700.

These and more ATS links, and links to many external sites you can find in my signature block and in the signatures of others.

Never be afraid to ask a question. We will always try to answer, and no one gets ridiculed here because of a lack of knowledge on what is a complex and multifaceted subject. (Well not if the question is reasonable at least!)

It is somehow strange, because I never had such a feeling, but somehow I have the feeling there will be another bigger or even big one in Japan within this year.....

I cant tell you why, it is just a feeling. Maybe it is just because I miss my Japanese girlfriend a lot at the moment and will not see her the rest of the year...

What the heck is going on in the Carib?

I am new to this quake watching, self learning...so let me know if I shouldn't be interested in this.

that particular spot has been having swarms for quite some time if you scroll back a few pages i believe puterman talked about that particular area the largest eq so far in that swarm area was back on 9/4 at 5.2 but worth keeping an eye on.
