Didn't have a clue what was going on then it hit me (Liverpool).
I have just awoken to the whole room shaking and a huge rumbling noise at 12.58am here in Sheffield UK. Knowing this would a quick way to find out what happened I whipped out my iPhone posted here. So was it an earthquake?
It was most definitely an earthquake. Waiting to see how strong (weak in other countries terms) it was.
An actually fairly significant quake.

Follow that link I posted and you'll be able to report what you felt, which will be mapped automatically by the USGS. Always quite interesting, and even more so since I've never seen one mapped in the UK before!
Just filled it in, will be quite interesting to see the results of it.
You'll probably find people further away reporting feeling more shaking than people nearer to the epicenter.
I was just about to ask because I got III where as some one from St Albans ~ 150 miles away got IV but of course it is slightly subjective.
It's somewhat subjective, and highly dependent on where you were when the shaking started. Above the ground floor amplifies the affect, wood frame building as opposed to masonry, etc. It also depends on your local geology. Based on the location of the quake I would expect some pretty good shaking to be reported in the Fenlands. Lots of liquefaction potential there I'd guess.
I have since changed my post after I realised I read the wrong line, I scored a V.
So are you some sort of geologist. My dad did a degree in geology and I find it fascinating.
