Iceland warns of threat of big earthquake

(Reuters) - Icelandic authorities warned people in the north of the island on Thursday to prepare for a possible big earthquake after the biggest tremors in the area for 20 years.

The north Atlantic island, where almost 320,000 people live, is a hotspot of volcanic and seismic activity as it straddles a fault in the earth's surface.

The Civil Protection Department said in a statement that recent small quakes in an area under the sea about 20 km (12 miles) off the north of Iceland had prompted it to issue a warning to local people.

It said such shocks, one of which was a magnitude 5.6, often led to stronger quakes. Warnings were issued when there were grounds to expect a natural or manmade event that could threaten health and human safety, it added.

If there has never in 112 years been a Mag 6 in that area why the warning?

If I lower the magnitude in the search to 5.0 I get

Strange that the ANSS does not have this one in the Centennial Catalogue

1963-03-28T00:15:50.400Z, 66.274, -19.877, 6.8Ms, 15.0000


So now I am even more puzzled. The range in the Centennial is from 6.6 to 7.0 depending on the source and scale. The location is a little away from the current swarm, but not that far.



From the article


Geologist Benedikt Ofeigsson said houses in Iceland could typically withstand quakes of a magnitude about 7.


Guess that should be OK then, but I still think this is a bit of an Italian Job.

I forgot to add, this was the year that Surtsey Island appeared off the South coast of Iceland at Westmannaeyjar. I remember that event very well from the newspaper coverage at the time. I don't however recall any mention of a large earthquake in the North of Iceland.

It does not get a mention here yet it is comparable, in fact larger than, the Skopje quake (6.3) also in 1963.

 

Stærri skjálftar (>4) á árunum 1706-1990 Basically a list of earthquakes in Iceland over Mag 4.0 between 1706 and 1990.

The 1963 is down as 7.0 and I assume that is ML

OK I have filtered those by the same criteria and what we are left with is:


tími lat lon stærð fjarlægð frá kennileiti
1872-04-18 10:00 66.0 -17.5 6.3 8 km VSV af Húsavík
1872-04-18 11:00 66.2 -17.9 6.3 4 km NV af Flatey
22/01/1910 07:48 66.5 -17.0 7.1 32 km NV af Kópaskeri
02/06/1934 13:43 66.0 -18.5 6.2 3 km NNA af Dalvík
28/03/1963 00:16 66.3 -19.6 7.0 30 km NA af Hrauni_á_Skaga


It would seem that there is a chance of a mag 6+ every 30 years or so which makes it very much overdue for a bigger one. Why in the heck to they not just explain that instead of being so mysterious and making us go and search it out?


Here they are plotted for you.



And finally, is that 1910 M7 one you do not have Muzzy?

Ok bit new to this
was looking for the P and S wave indication and could not make it out

or it only happen sometime.

that seismo must be right on top of the epicentre, there is no P wave just the S wave.

Tjörnes Fracture Zone activity is still going after 6 days. This is uncommon event. Activity is decreasing, but there is still threat of larger earthquake. There was a rock collapse after Mw5,6 earthquake.

According to Icelandic Meteorological Institute, there is enough stress for Mw6,8 earthquake. Decreasing activity is not sign of that threat is over.

2°C? Try the middle of Greenland.

Down to -50°C a couple of nights ago. Positively tropical now at -24°C
(Bear in mind this is at an elevation of 10, 500 feet, Summit Station is located at 720 36' North, 380 25' West on the summit of the Greenland ice sheet. The current mbar is 667 because of the height.)

Never used it but it is out there.

Or this 162 page document of Japan seismicity. (Bear in mind when you get to the paragraph on Fukushima that this was written in 2005.)
