Earthquake!

[Reference Info: Mini earthquake. OK, barely-perceptible tremor. But Melbourne is not on a fault line so this is exciting for us... humour the crazy people here.]

I have decided that fatigue disorders give one awesome detection ability for earthquakes - I tend to spend almost all my time lying flat in bed without moving and have thus felt 2 of the last 3 decent quakes in Melbourne!

I was asleep during the middle one, which tells you one of the drawbacks of fatigue for an earthquake spotter... :)
