Plant was shut down, and the entire area around it evacuated.
The UK sits, what, two thousand miles from the mid Atlantic ridge? And it's a divergent boundary, not a convergent one like the plate Japan sits next to / on, so there should be less in the way of earthquakes for us anyway... but much more in the way of volcano eruptions.
I think our closest convergent boundary is in the Mediterranean, between the Eurasian and the African plates... but correct me if I'm wrong.
Personally, I think plate tectonics is absolutely fascinating. Got to wonder how much smaller the pacific plate is now (inches, at the best).
Also, as a little interesting side note. Since the 8.9 this morning, there has been a further 120 quakes (At last count) since then that have measured above or around 5, and a few 6s and 7s on the Richter scale in and around that plate boundary. No idea for the ones that measured less.
Not a good place to be in at the moment.
