Earth Tremor in the UK

We had an earth tremor about 40 minutes ago. My whole house was shaking! Poor K's bed was moving, as was the chair I was sitting on. It must have only lasted about 20 seconds, but it felt like it was never going to end! Everything was moving. The last time we had anything like this was about 6 years ago, but this felt much stronger than that one did.

It was quite scary while it was happening. My poor legs felt like jelly when I rushed in to K's room. She's sleeping now, but it frightened her while it was happening.

Wow. I've never felt or heard anything quite like that before. I could even hear and feel the rumbling under my feet.
