Quake Watch 2010

Awww, give me credit - I didn't count the 2 Norwegian ones!!! Otherwise would have been 14 (and I'd have been pushing my luck!)

I was giving you credit as you said 12 and there are 14 on the list. Let's not fall out over this!

But that still leaves only 9 and one has to question if Islay is part of the UK (Ah the single malt!)

I do find the UK figures impossible to get hold of. There is a whole load of useless rubbish on these pages most of which only give intensities as I recall when I trolled through them. Then you get this one which is almost as bad.

One of the larger 'swarms' was the 2002 Manchester one with 70 between October and November.

Source

While it appears somewhat unusual to get that many earthquakes within only a few days, this has been previously observed in the UK. Such earthquake sequences can occur in two ways. Firstly, moderate to large size earthquakes are usually followed by aftershocks, which occur due to readjustment to a new state of stress. The pattern of the aftershock sequence depends on the size of the event and the local tectonic setting. Normally, the largest aftershock is about one magnitude unit smaller than the main shock. For example, the magnitude 5.4 ML Lleyn Peninsula earthquake that occurred in North Wales in 1984 was followed by some 25 aftershocks in the subsequent two months, the largest of which was a magnitude 4.3 ML earthquake that occurred one month later. Secondly, earthquake swarms are sequences of earthquakes clustered in time and space without a clear distinction of main shock and aftershocks. Examples of such swarm activity in the UK are Comrie (1788-1801, 1839-46), Glenalmond (1970-72), Doune (1997) and Blackford (1997-98, 2000-01) in central Scotland, Constantine (1981, 1986, 1992-4) in Cornwall, and Johnstonbridge (mid1980s) and Dumfries (1991,1999) in the Borders.

is the location of the UK quacke not the same position of an agient supervolcano????

I did find this Borrowdale Volcanic Group

The Borrowdale Volcanic Group is a volcanic group of rock formations named after the Borrowdale area of the Lake District, in England. They are late Ordovician in age (roughly 450 million years old). It is thought that they represent the remains of a volcanic island arc, approximately similar to the island arcs of the west Pacific today. This developed as oceanic crust to the (present) north-west and was forced by crustal movement under a continental land-mass to the present south-east. Such forcing under, as two plates meet, is termed subduction. This land-mass has been named Avalonia by geologists. It is now incorporated into England and Wales and a sliver of North America.

I'm only about 30 miles from the epicentre of last nights quake in the UK, I thought it was just a truck sitting outside, felt similar, although when I thought about it, it was a bit stronger, and different. As I have said in the thread I made on it, as small as it was, I'm just pleased I can say I have finally experienced an earthquake

EDIT: 27 miles as the crow bimbles, cheers google maps, lol.

edit to add: cancel 6.5 North Pacific Ocean

pretty large mistake I would say

Hey check this out...

the 6.5 in the North Pacific that was there for about 5 minutes and then taken off was in the news.

Strong earthquake strikes the North Pacific Ocean, northeast of Hawaii

A strong earthquake struck the North Pacific Ocean on late Wednesday morning, hundreds of miles off Hawaii, seismologists said. The 6.5-magnitude earthquake struck about 873 miles (1404 kilometers) northeast off Hilo, Hawaii. It struck about 8.1 miles (13 kilometers) deep, making it a shallow earthquake, according to the West Coast and Alaska Tsunami Warning Center. The tsunami warning center said no tsunami was expected.

It was Santa. He had been to Hawaii and was on his way to the US when he was intercepted by a US Homeland Security fighter demanding that he stop to have his junk felt. When he refused they shot him down. Sorry Folks. Christmas has been cancelled this year thanks to Homeland Security.

There was not a sign of it on the seismos POHA.IU.10.BHZ.2010.356 or KIP.IU.10.BHZ.2010.356 so I have no idea where they dreamt that one up from!

Actually it makes you wonder if what we see on these seismos is real since it is all electronic and not a paper trace. Something must have triggered the computers yet there is nothing to be seen.

looks like Channel 6 News were in such a rush to break the news that they didn't bother to cross check their sources and only used one network's data (USGS) to create a story. They probably use that usgs e-mail alert thingy.

I wonder if they will print a retraction? yeah right

how long was it on before it was withdrawn berkeleygal?

EMSC now downgraded it to 5.5. The USGS one did come in.

The competition is on to see who can make it the lowest Magnitude!

reply to post by PuterMan

looks like 2 quakes on that graph, USGS magnitudes probably azz backwards the 2nd one looks bigger

Less than 5 minutes. Long enough for me to see it, post it, and when I went back to the page it was gone.

98 aftershocks in the Bonin Islands, and one of those was a 6.3 - 99 total quakes. Its not over yet.

OMG...thanks for the laugh. That was a hillarious post.

So did you guys notice how after the Alaksa quake (6.2 mag USGS), it seemed to quiet down significantly in the Japan region? Obviously hasn't stopped, but it did slow. It makes me wonder where else on the ring this little volley is going to end up?

Any takers?????
