Earthquake!

We live in an earthquake zone here and we had our first noticeable tremor this evening.
We heard it approaching, it took until the shaking hit us to realise what it was. It sounded like a wonky spin dryer coming closer and then the whole house shook quite significantly. Nothing fell apart or broke though. I guess the house has survived many many of that kind of size. Apparently there is a bit '100 year' one which is well over due. The house hasn't survived one of those as it was built just over a 100 years ago!
