A powerful earthquake has struck south-western Panama, close to the border with Costa Rica, says the US Geological Survey (USGS).

The quake was reported with a magnitude of 6.2 and happened at a depth of 48.2km (30 miles), monitors said. The epicentre was close to the Pacific coast and 55km (35 miles) west of David, Panama's third-largest city and home to 125,000 people. There have been no reports of any injuries of casualties, says the USGS.

Was awoken by one on 27th December. Turned out to have reasonable magnitude in the end. Since then, not felt anything.

Reference Number: 3021098

NZDT: Sat, Dec 27 2008 8:49 am

Magnitude: 5.1

Depth: 50 km

Details: 60 km north of Porirua

My earthquake preparedness kit (in case of The Big One) is still not very complete :oops:

Have plenty of water, a tramping stove and some gas, but a bit limited in every other department.

Seismic activity been very quiet recently (I hope that doesn't mean something...), only one 5.0 + quake in the last month.... :/

I wondered what it was that woke me at 0530 this morning, I thought it was the wind!

BBC News - Shetland earthquake

Yes, they always seem to feel like that in the morning :D

Turns out it was a Mag 3.3 quake with its epicentre 17.5km below the village of Aith, in Western Shetland.

Rather weak quake, but I assume the shallowness is what made it noticeable?

Aparrently there are about 3 quakes of this size per year in the UK. Shetland is seismically quiet and this is the first quake on land since a Mag 2 event on Unst in 1886.

Some excellent info from BGS:

BGS seismogrammes etc

That sounds like the UK as a whole is very seismically quiet?

Relatively speaking. There are areas which are fairly active but at a low level, like the Great Glen in Scotland and the UK does get the occasional quake of the order of Mag 5.

It is very unusual to have an earthquake in the UK, let alone the Shetland Isles! Due to the Uk being no where near a plate boundary, its a very rare occasion.

I think there are a fair few small ones every year though as there are many minor fault lines across the country. There is a table somewhere of how often earthquakes occur in Britain I'll see if I can find it.

Here it is http://www.earthquakes.bgs.ac.uk/earthquak.../faqs/faq6.html, there around 200-300 earthquake detected in the UK every year albeit small ones, which is more than you would think.

Sorry! Let me re-phrase it- I have not explained what i meant very well!......

There isnt many earthquakes that are felt and most are of a negligable amount. I think there was one local to me in 2002 in Dudley . It was upgraded to 5.1 i think.

James M-Thats staggering! So theres on average an earthquake in the UK every 2 days!?

It is suprising isn't it, obviously most of them won't be felt but that's still a fair few every year that are.

Its hard to grasp. The UK, a quite stable landmass in relation to tectonic activity, has an earthquake roughly every 2 days! Do you know or have you any data as to where the focus/ epicentre is for most of these UK earthquakes please? Im intrigued!

Thanks!

Ah i see you have just answered my question-Thanks Jane-Louise!

There's also this interactive map which shows them in more detail, plus lots of other interesting data.
