Either that or we just tested a 22 trillion megaton nuke under the Pennine mountains.

I'm up in the North of England,  saethwr who is up here in the Cumbrian area also reported that he felt a 5 second shake.

I could actually hear the ground shaking and the house creaking.

I'd actually like to feel that again just to feel the shake. Out of curiosity, I hope it doesn't jinx us with a 8.0 quake now :P
