Interesting reading about earthquakes and tectonic plates. British Geological survey have recording stations for seismic activity all around the UK . The nearest to us is Elham. Check out Elham and Market Rasen for the 11th February, you will be surprised... nay shocked! and we are on the otherside of the world !!!

Also for those who may be interested check out constuctive plate margins (part of the driving force for plate tectonics) and destructive plate margins. Oceanic crust is no more that 190 (circa) Ma (million years old), it always is subducted or obducted, (Alps and the Himalaya). Continental crust has been found in places to be up to 4,200 Ma.
For information on how the quakes could be "felt " here, look up P waves and S waves.
As for 'boring' at these areas , one does not realise the depths involved and the the immense pressures involved. Iceland can tap geothermal heat due to the source proximity to the surface, but that is one of the few places were it can be done safely.

One my main fields of research was conducted in Iceland, Not thinking it would be relevent to the UK until last year's eruptions !
