Has Israel run out of patience? LOL

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

I'm against western bullying of Iran over its nuclear program, but this could raise some serious questions, and/or accusations.

IRIS is tentatively listing at 6.2. It is very shallow...9.7 km

From the map in this article it looks like the research reactor at Bonab or at Ramsar would be closest to the epicenter.

Is the Underground Nuclear facility safe

It would be ironic that they would bomb iran when Romney is making is VP choice today just saying.....lol

I dont know how to post a pic. Located this from BBC.

I have no idea, but any underground detonations would have to be many many miles from any inhabited areas.

EDIT:

The explosion produced a 4.7-magnitude tremor, according to the U.S. Geological Survey. The previous nuclear test registered 3.58 on the Richter scale.

Th earthquakes seem to be located between Tabriz and Ahar. Looks pretty mountainous.

These were followed by a 4.8 and 4.4 aftershock.

This is a good site to follow for information

earthquake-report.com...

I started a thread as search did not bring up yours. I have asked the mods to delete it.

Can you please repost your opening thread here then.

Very good info and sums up events better than my scatter brain job.

Thanks.

2 Magnitude 6 earthquakes have struck in Iran only 12 minutes apart and both shallow.

They were close together. Some very heavy damage and loss of life could result from these.

More details shortly.

the PAGER estimates are not in yet.

Earthquake report have not caught up with the fact that there are two yet, but when they do you will det excellent data from that site.



From the above link

The closest city to the epicenter is however Ahar, a city with a population of 94348 (latest census).
Theoretical intensity calculations are expecting very strong to severe shaking in the epicenter area.
We will start-up an in-depth article as soon as possible.

RSOE have it down as three quakes,

anyone confirm whether or not it was three quakes, not two?

thanks

Thanks for that. The site you mentioned is good and was where I found the breaking measurements.

USGS Pager data in now.

The first earthquake is an Orange Economic alert

Orange alert level for shaking-related fatalities. Significant casualties are likely and the disaster is potentially widespread. Past events with this alert level have required a regional or national level response.

and a yellow economic alert

Yellow alert level for economic losses. Some damage is possible. Estimated economic losses are less than 1% of GDP of the Islamic Republic of Iran.

The second PAGER detail is still pending.

Here is a constant update, there are already 4 aftershocks bigger then 4.0...

From your link Lunti

Update 13:13 UTC : We have no record of historical earthquakes close to the current epicenter. A 2002 earthquake with a Magnitude of 6.5 at a distance of +300 km from the current epicenter was unfortunately deadly for 227 people. In other words we think this is really a dangerous earthquake. Luckily most people will have been out of their houses at the time of the quake.

I am assuming this means no record of significant earthquakes. What defines an "historical earthquake". Is it above 4.5.
