Hi fossy. Not saying that I am right, but you should perhaps take a look at this before devoting too much precious time to the study of 188.

Phage also did a study of this and came up with several more apparent 'cycles' No doubt if he breezes past he will give you a link. Alternatively track him down and look on his threads.

data from International Institute of Earthquake Engineering and Seismology

180 deaths,1300 casualties according to the radio news

ETA: I accidentally downloaded the entire Iranian database since 1901 when searching for 50km radius circle around Ahar historic data, juicy stuff, 14,004 entries above Mag 3.0

Took a bit of sorting, converting UTC to IRDT is a nighmare as the date changes as well as the time for the first and last 3.5hours (4.5hrs IRDT) so ended up just using IRST, well they didn't have IRDT back in 1901 did they


heres the history for the area, sorted by Province which is about 150km radius around todays events.
Not a lot going on above Mag 5 in the past.
I can't use the numbered icons because there are already more than 31 aftershocks (the limit on GMaps), so I have reverted to theoldblackdot to mark those ones in this series.

Well, unless any quakes of significant size appear before then, I have predicted that the 19th of August will be the next date when something big appears.

This theory of course has no founding, only the 188 day theory has influenced my predictions.

not to generate any more debate on the "188 days" issue, it's not due until Sept 25th 2012 ... just sayin'...

missed the end tag on the 2nd interactive link, too late to edit it now (stupid ATS restriction, because most of the time its spelling or formatting that is the reason to edit it)

Ha! my birthday

These Ahar quakes related to the Van, Turkey quake last year maybe?
only 300km away
I been reading about historic Syrian quakes geez its amazing the devastation they've had over the years whole cities destroyed over and over Antioch mainly and Allepo, every couple of years back in the period 0-1000AD seems like the faults were swallowing whole towns up the people never seen again.
Probably the same in Iran too.

reply to post by muzzy


does that map correctly show all fault lines in the area or are those quakes just in the middle of a plate?

BTW thanks for all the great mapping WOW the work put into that .

And Erev Yom Kippur this year as well!

You may be right about those Turkish quakes, especially if the focal planes match up.

One of the big things about anything that we say about earthquakes like "unprecedented", "never happened before", even "rare", is that it is all very relative. With recorded history being a few microseconds in the 24 hours of earth's existence it is not possible to make such statements.

Each 1000th of a second represents 52 years if we accept that the Earth is 4.5 billion years old. Written history @ ~3,500 years is a scant 67 micro seconds (just 67/1000 ths of a second)

One second is 52,000 years yet that is only 1/86400 th of the Earth's day.

If I am lucky I will live for 2 whole microseconds. It is sobering, yet we pontificate about what is 'normal'?

This image shows the fault systems in Iran


Source: Somewhere on the Iranian Seismic Service site.

I have not overlain the map on the earthquakes to see if there is a fit, but as you can see Iran is heavily faulted.


Here you go - a very quick and not quite perfect job.

Doesn't it? If you mean F on the fault systems map.

Edited data to avoid duplicates.

Same here. Didn't see your post as I was typing up PuterMan's long ole format.

No problem, I'm just pleased there are other people out there who are interested in this stuff, makes it worthwhile, making the maps is relatively easy, its the processing the data that takes the time. At least now I have the Iranian database converted into an Excel file I can use in the future.
I see Puterman did a couple of maps with the faults on them , looks like these quakes and the aftershocks are at right angles to the main faults.
I di away with the blackdots after that, looked like black eyed peas

I haven't got the time this Monday morning to find out what you mean by "focal plane", but the moment tensor solutions are all different (I used Geofon), even the two Iranian quakes have different beachballs


I haven't looked at USGS MTS's yet to compare, maybe when GCMT come out with the latest quake data it will be worth another look

update on Ahar, Iran aftershocks, 122 so far to 13/08/2012 21:38:42 UTC
interactive map
did it in a bit of a rush and screwed up the local times and lost the depths, but UTC and mags are on the popup tags for now. I'll probably do a page on eqarchives after the 72 hour period is up, with a timeline graph (marble spill) and fix all that.
I've marked the RAS locations for the mag 6's as purple icons, they are a bit south of the Iranian locations, and as it happens closer to the faults Puterman showed on those maps yesterday.
The gridlike pattern is due to only 2 decimal point numbers on the Iranian data.

308 fatalities counted so far (including 219 woman and children) according to earthquake report.com

Hi Guys,
I've replied to muzzy so this ends up at the bottom of the thread. I only really lurk here but love what's discussed etc and appreciate all the stunning work that's done (particularly Puterman & Muzzy)
I was wondering if somebody could explain how a earthquake can register as with a depth of 1 metre. I use the quakes app on my phone and the depth is actually 0.1 km, although on the info I copy/pasted it says 0.
Apologies if I've asked what has previously been answered.
Cheers
Jd

A 3.5 magnitude earthquake occurred in "Central California" (Longitude: -117.672°, Latitude: 35.948°, Depth: 0 meters) on 13 Aug 2012 14:03:47 UTC.

i just wanted to throw out there that Alaskas recent EQ's seem to be moving inland....this worries me a little. If you look at the map as a whole there are specific areas in the last 2 weeks that are seemingly more active than usual. Don't want to fear monger but I get the distinct feeling something is brewing.

thanks for the compliment

usually 0km come up where the quake is under a volcano.
In this case its the China Lake Naval Weapons Center so could have been a big explosion.Who knows what they are testing under those hills, there are roads (tracks) running right by the location, perhaps there are tunnels under there.
