Alaska is getting some pretty decent sized activity.. wonder what's up.

Southern California/ Baja Mexico is also increasing slightly in the size of their grumblings.

Sorry about that - things starting to roll

I only add these two because of the location.. just out of Iceland and due to the focus on the volcanoes that everyone seems to be focused on..

one on top of the other.. just not as deep, although both were pretty shallow.

Thanks Broahes I was wondering at first if it was a double post by USGS given the identical co-ordinates and just a revision on the depth.

Does anyone know if these earthquakes are close to the current eruption or perhaps another volcano on Iceland ?

reply to post by broahes


I checked on Google Earth. 66.40 N ; 18.77 W is north of Iceland in the Atlantic

reply to post by zachi


Yeah, I did that after my post.. I thought it was right on the coast..

I was more curious about what those that know more than I do thought about them being right on top of each other and that shallow.. just struck me as something a little odd, and maybe a sign of something.

You can see the quake locations on the Iceland Met Office website here:-

en.vedur.is...

Nearly all of the recent quakes have been outside the Eyja/Katla area.

Did you folks miss this one? I could not see it in the posts.

Magnitude mb 5.0

I find it curious especially since Iran has been playing war games there, and the trace (Eilat is the nearest I can find) is peculiar I feel. Anyone have any comments on this long drawn out signal?

I was about to say that it's the same one I have posted above you.. but I see that the depths and such are way different.

I agree with your thoughts on the war games. Especially with the pretty shallow depth of the one that I posted.

reply to post by broahes


You are right my apologies. Obviously different sources. Mine was EMSC. Sorry I did not see yours - actually looking at the times I think you posted while I was composing as it took some time to find the plot.

Take a look at this plot as well from Saudi Arabia

RAYN.II.10.BHZ.2010.117

I find that VERY strange for a smallish earthquake to leave such a signature. The Israeli recorder is nearly 2000km from the epicentre, and the Saudi one is about 1000km.

Whoever is interested in staying up to date with earthquakes should seriously use this: www.disasters247.com... it's really easy to read and if you check it regularly you should begin to understand earthquakes better..

I thank you for your input, but I at least will not be adding this site to my arsenal of information! There is little on the site that would assist me in gaining a greater understanding of earthquakes.

Most of it's information goes straight back to USGS and thus is not a 'new' source to most of us on this thread. I have had a good look through it and find it limited, a little patronising or even condescending, and riddled with advertising. If you choose to use this site make sure that you opt out of advertising on the 'about us' page.

My own personal impression is that this has been put together to satisfy curiosity of users and create advertising revenue for the site owners. This is not knocking them, after all ATS does the same, but since I can get fuller information direct from the USGS horses mouth I can see no benefit in visiting that site in the future.

I would also say that in relation to that site you would probably get a greater understanding of earthquakes by reading the various threads on ATS.

Do you have any idea what the actual depth was closer to? As there is a huge difference from your source and mine. Mine was USGS. I do find it to be a little odd, the length of the event as recorded.. but couldn't depth play a part in that?

Very quiet in New Zealand last 24, just the one other 3+ than the Carterton 3.4

Doesn't bode well, I'm not into predicting quakes, but in the past a downturn to this few quakes in 24 hrs in the past and a 5+ has hit.
