7759 Earthquakes in last 30 days

A friend of mine told me last night they'd felt a 3.7 Earthquake in their house in south Portugal on the Thursday evening. I was browsing the web for new and came across this site which gives real-time earthquake information. At the time of typing this there were 7759 recorded earthquakes in the last 30 days. I'd no idea that they were so frequent.
Now Zen, but a +Net residue.

Choosing one of the RRS feeds on this site gives them to you in real time, (can be imported and sorted with excel)
Utilising the results from the RRS feed with something like openlayers (http://openlayers.org/), enables you to overlay the earthquake feed onto Bing, or Google maps. 
Then it can get interesting ( Undecided)as you can 'select' by region, depth, magnitude, time scale and period (seismic swarms) and display on your own map/web-site.

Link to the British Geological Survey's UK earthquake database in last 50 days plus links on page to historial UK seismic activity
http://www.earthquakes.bgs.ac.uk/index.html
Largest magnitude recorded 6.1 in 1931
Largest damage recorded Colchester area 1884
I think it depends on how deep they occur as to how much surface damage occurs
As well as still being slightly uplifted generally due to rebound effects after the last glacial age finished and the weight of the ice sheet over the UK was removed, the UK is also tilting slightly so that the West coast is rising and the East coast dropping.
Somewhere (it was not online) I've seen a very ultra-long term mathematical projection of the movements of the tectonic plates over the next few 100 million years - it's quite extraordinary.
The Africa moves upwards to close the Med' completely
East cost of Africa splits at the rift valley completely to move towards India
Spain/Portugal rotate clockwise and up to almost lie next to France which is squashed (skiing would be good in the Alps!)
S.America goes somewhere - can't remember where.
The UK area moves South West while remaining in its current orientation.
I'll see if I can find my copies of the data...........its somewhere here...maybe..

This seems to be  the sort of thing x47c was describing.
