Nothing out of the ordinary there. In fact it has been quiet which was why I was expecting a bigger one.

Now, Iceland - and this is NOT Reykjanes

Tjornes fracture zone I think, or very close by - yes it is. Possibly volcanic as it is centred off the ridge and there are several underwater volcanoes there.

If you are using Windows 7 using the snipping tool, just start typing snipping into the box and it should pop up!

I remember driving up that way on a visit to the USA in 2000...very scenic trip.

A 5.3 would have ROCKED pretty good! Hope it's a one-off for y'all!

Uptates ended for now time for bed Zzz Zzz

Heavy activity at Tjörnes Fracture Zone in Iceland. Largest earthquake was 4,8 magnitude. There has been massive amount of earthquakes during last 48 hours: 374. 48 of them were more than magnitude 3.

I have never seen such high activity in TFZ. That area is full of volcanoes, this high activity can cause changes in them, triggering eruptions.

I rarely post, but this seemingly not-unusually sized CA 5.3 quake was felt strongly by us, despite the distance from us, and many other Californians:

M5.3 - 26km ENE of King City, California

reply to post by Thebel


Actually it was 5.2 according to the Icelandic Met Office. (And EMSC)

This also apparently started at the end of September based on this report

Earthquakes are not uncommon in this area, comparable earthquake sequences have occurred in 1996 and 2004 around the same location as the present one. They lasted for several days and earthquakes above M4 were measured.

So despite my musing in my earlier post about this above it seems it is tectonic and not volcanic. The very shallow depths of many of these were making me think volcanic.

This made me get off my backside and get on with my uploads of Icelandic quakes to YT which I last did in May!!

Here is September 2012 so you can see the activity in the area we are concerned with.



I find You Tube very messy and unordered so I have assembled my Iceland Videos starting on this page in a more ordered fashion. I shall add earthquake lists to this later in a similar fashion to the Cascades pages on the blog.

I hadn't spotted the USGS one as I tend to use EMSC for Iceland. I note Geofon has this at 5.6 as well.

EMSC is 5.2 mb as also Iceland say, so I wonder if they are using mb as well? 5.2 Mw is ~5.58 Mw so it would seem they are all singing from the same hymn sheet.

Looking at one of their weekly data files that I collect (and then never look at again [ yet ] )

Nr Dags. Timi Breidd Lengd Dypi M ML
1 20121001 000032.187 63.94799 -21.33988 6.470 0.33 -0.29
2 20121001 001523.369 66.51197 -17.57926 15.151 1.77 1.71
3 20121001 001944.621 63.96586 -21.57715 6.053 1.81 1.43
4 20121001 025942.996 66.57095 -17.78790 13.469 1.60 1.58
5 20121001 030323.671 66.52032 -17.58202 16.583 2.64 3.00

It looks as if they use ML and 5.2 mb depending on the parameters for ML of course could be ~5.4 Mw so not that far out.

Injection well 1.2km to the east.

I live in California, a little over an hour north of King City. From my end, it was a pretty good shake, lasted maybe 20-30 seconds. Seems like we haven't had one in a while, atleast not any that I've felt clearly.

edit on 10/21/2012 by chupacobra because: deleted external link to map contained within enclosed link.

The quake was on a major fault line so I think that's why it was felt so far away. I was pretty freaked out by it and I've lived in Cali all my life. I'm just happy there weren't any bigger quakes to follow!

I was reading a book on my bed and I thought my wife, who was sitting at the computer desk next to the bed, was pushing the bed with her foot or something when the earthquake happened. I live about 2 hours away from King City. It was a weird feeling, especially since this is only the second quake I've actually felt this much.

Aw what the heck its a Labour Day Holiday Weekend, its blowing a Gale so what to do?
Hmmm I know lets show USGS a thing or two

US and Territories old style map layout (mag 3+ only) using thie own data.
2585 events
5170 icons (one set of maps with them all on it, and 9 sets of the regions)
40 maps
4 graphs
It will take a little time to load
a few screenshots of points of interest
Oklahoma (not many)


Andreanof Islands, Alaska ( quite a few)


Brawley (there were a lot more green icons but still quite a few mag3+'s too)


Virgin Islands ( Holy Cow)


and the graphs (this is a thumbnail, click on it if you dare ........ not a lot of quakes really)


I'll do an update after the end of Oct. and add another set and the graphs will change.
Might have to do a separate page for each year, its a lot of html code to feed on and keep it in order, I lost my place a few times.
