2 6 Plus EQ hit northern Iran

reply to post by Irishone


It was two quakes

You can see them on this:GNI.IU.00.BHZ.2012.224

I think they noticed that there have never been (significant) eq's in that specific area, which is unusual.

What sort of effect does underground nuclear testing have on seismographs?

It shows up similar to an earthquake but the signatures are different on further analysis.

There is quite a lot about that on the web if you are interested in researching further.

By the way the direct link to the Iranian seismic service is here
(PS it is getting heavy traffic at the moment so you may not be lucky)

The seismogram linked above is the closest publicly available seismogram and in located in Armenia.

This is (as far as I know) the fastest tracker of eq's, You have to refresh sometimes and keep in mind that the site combines multiple sources.

It is no faster than anyone else as, like me, it gets feeds from USGS, EMSC and others. It can also be very slow to recognise deletions and revisions so be careful.

Remember the Canadian Mag 10.3? It was a -0.3 and GI software could not handle that.

Live Earthquake Mashup is good but I believe one of the fastest is Earthquake 3D (A program) which uses the 1 minute USGS feed (I think) that I use for my Rapid View Just checked. No it does not so it won't be any faster then the others.

From earthquake-report.com...

Important update 13:43 UTC : WAPMERR, the theoretical earthquake damage engine, has calculated that based on the Geofon earthquake data and epicenter, 100 to 500 deaths may be expected. Our experience with Geofon is that this estimate will be hopefully reviewed to lower numbers (like often elsewhere). WAPMERR is however an indication that this earthquake is a really dangerous one!

After looking on google earth I thought this area was just mountains but its actually quite a populous area.

Actually, according to a data plot I have generated, I count like 9 quakes so far- but those include some sub 4's, not being reported by USGS. GNI is about 350 km or so from epicenters, so there may be even more than that, smaller not seen well at GNI. But the fault is definitely rocking. Two more smaller now coming in...


and two more after that.... That fault is moving, no question...and these are like rapid-fire, back-to back now...


Now settling into a lull (no activity)... I'd say it appears to be a typical mainshock/aftershock sequence, except that the magnitude differential between mainshock and 1rst aftershock is pretty close. So it's possible they are foreshocks, but not likely. Also, the magnitudes might get further revised in few. From my data plot, I can see the second one may come down a bit in mag... But overall it appears to be slowing down, as one would expect...

scratch that, another aftershock hitting now, smaller, maybe a 4 or so again.


and now again, another, 4 ish


And again, it continues with another smaller one...Last report of smaller aftershocks unless a real big one occurs.

the other thread by puterman was WAY better than this OP. As in, a much more informative landing post. I vote we at least keep the other one open

reply to post by Gwampo


LOL im the OP and I agree. Will the mods comply. Would be happy for them to close this and run with putermans to be honest.


Definately go with putermans. Just been reading some of his work. He should get credit for well thought out and constructed threads on a topic he clearly knows a lot about.

interesting activity for sure. a screenshot :

Here is the list of earthquakes in a 2 degree spread, so about 117 mile radius of the epicentres. Sorry it took a while to find it on my computer.

What sort of effect does underground nuclear testing have on seismographs?

It shows up similar to an earthquake but the signatures are different on further analysis.

There is quite a lot about that on the web if you are interested in researching further.

The green graph is nuclear explosion

And black graph is a Earth Quake with it P & S wave foot print

That would hardly be fair now would it?

I am happy with mine being closed. I shall continue to post here.

That really does not tell the whole truth. I know that image. A quake would look the same as the nuke if it was close up like the trace from the nuke is. The trace from the quake is much more distant.

A bit of scientific trickery I think.

on the live seismic server page, i count 33 of the 94 listed stations showing 'sorry, telemetry data are presently unavailable'. this seems a lot, or is it not unusual?

puterman, if i am reading what you posted correctly, while the region (wider area) experiences quakes of significant size this particular area is not so prone.

Is that significant.

While your on the thread I would love an answer to another unrelated topic. Due you support the theory that the asia-pacific plate activity (Indonesia, Papa New Guinea) is causing stress elswhere i.e. the quakes in inland Australia

It is indeed unusual to have so many down at one time.

I is often three or four, or all down.
