Quick Update on the Saudi Arabian Earthquakes

Amazing picture. How recent is it?

That doesn't really look like a "fissure" to me so much as a crater from some kind of phreatic explosion. The debris scattered around the openings would tend to reinforce that conclusion in my mind. Lighter material (sand, dust, etc) would likely have blown away in the wind but the rocks appear to remain.

hi ERIK
I think the google translator doesn't give a correct translation because you say "This bring the total earthquakes to over 150 since seismicity began a few weeks ago" this is not wright, they mean just during 24 hours (from 12 o'clock on last Wednesday to 12 o'clock on last Thursday).

extra information

the whole number of earthquackes has happened over a few weeks ago is approximately twenty four thousands and this doesn't involve last earthquackes.
this link confirms that information and describe the whole situation and involve some images for faults.

I'm sorry for my English

The pictures linked by Yahya certainly do look like fissures that could be caused by uplift to me.

Thanks, Yahya, for giving us non-Arabic reading people an update.

Has somebody a photo about Hala'l Bedr?
That volcano lies close to this scene and I can't find any photo of that but satellite images.

From Saudi news website.
The number of earthquakes continues to decline

Saudi officials believe once tremors remain consistently low for a couple of days that the 21,000 evacuees will be allowed to return home.

A personal reflection: Trying to get insight into future volcanic eruptions has helped develop my patience and humility. Just when I think a volcano is going to do or not do something - volcanoes have done something different.

I think it was Boris Behnke that said something about the next volcano that erupts is going to be the one that you are not watching.

(I think all potentially active volcanoes should be watched.)
Oh well, it is still fascinating.

Government officials who have jobs in the area are told to report to work.
Because of concerns about possible earthquake damage, houses are being inspected to make sure they are still strong. Residents will be allowed to return soon if earthquakes don't return.

Reading all these posts here mentioning cracks and sills - and now that earthquakes subsided after a moderately large earthquake leads me to wonder if the increasing magmatic pressure diminished at the time of the earthquake because the magma went into a sill? Now, the magmatic pressure is low and we won't see more activity until more magma comes up and sufficiently repressurizes the system? And of course, I have no idea when that might be. If the sill cools and hardens quickly would it make it difficult for more magma to later be injected into the same sill? Is there such a thing as a typical sill? At what point will scientists know how much uplift if any has occurred?

I realize we probably don't have answers to these questions.

Ok now this is kinda not only weird, but still plenty of weirdness after of reasons for it.

Abundantly handled and preparing for tradition

Great article, thank you! I really like it!

The closing paragraph tells it all in my opinion. I must say that I agree with it, and essentially the most fantastic thing about it is that you left it open endedâ¦this shows that you are prepared to draw in new and totally different opinions and that you are ultimately very interested to see folks getting concerned within the subject. So, any alternative opinions?

I am not very excellent with English but I find this rattling easygoing to translate.

Well, I do not know if thatâs going to work for me, but definitely worked for you! :) Excellent post!
