At 2:31:04 today there was a magnitude 4.4 (ish) earthquake at 11km depth just north of Swansea. Did you feel it?
I was sat on the couch when it shook in a sideways one-two motion. I thought it was one of my dogs kicking the couch in their sleep, but neither were close enough for it to have been one of them. My mum and brother were both upstairs and felt it too.
Here is a link to the USGS site, so you can see that I'm not crazy.
