Magnitude 6.2 WESTERN SAUDI ARABIA See note below

http://www.emsc-csem...date=2011-09-24

Please note there is a 95% error rate with this magnitude. I am trying to find out what would have caused so many monitors to go haywire. Many thanks to crepuscular ray for co-op on this.

Weird, it's not on their main list of earthquakes. The timing, however, was almost to the second the same as a far smaller one in Greece (2.7) so perhaps that was what they registered, really.

Greece and Turkey are enduring a Quake Swarm by the way. I do a lot of Earthquake research and there are some that are not mentioned on the main boards which is very strange.

[Crepuscular Ray]

From the look of it, the Saudi Arabian report you linked to was a preliminary one that was later refined and corrected. It does state that it has a margin of error of 95%.

You are correct regarding the 95% error mark. I would like to know what caused monitors to go haywire.

wow!!! just came in now and had a look at latest earthquakes.... how many earthquakes/tremors have there been on that volcanic island of el hierro today!!! could some one have a graph to show how active its been today????

[Crepuscular Ray]

I'm sure Yamkin will be only too happy to oblige.

Apat from that, you can view the larger ones on EMSC:

El Hierro seems to be a little quieter today.

according to USGS, there has not been an earthquake greater than mag 5.7, anywhere in the world in the past 7 days!

[bobbydog]

seems strange but they have upgraded a quake at katla to 3.3

04.10.2011 02:41:23 63.659 -19.138 1.1 km 3.3 90.05

Just curious, but have there been any decent size earthquakes in recent years in the Appenines region.

Why ?? I'm going to the Appenines in two weeks. Should I be worried??

Did not realise that was the Apennines. 95% link between large fairly shallow earthquakes in that region being followed by Vesuvian eruptions within a decade.
