Well ... it was only a little tremor, and I doubt that there was any damage done anywhere, but Melbourne had a small earth tremor about a quarter of an hour ago. It was a bit freaky sitting here watching everything shaking for what was probably only a few seconds but seemed to go on for quite a long time.
No news on the net about it yet, but I gather there was just something on ABC Radio.
Edit: Here's one story, though a bit misleading in its form as I write: we felt the tremor here, as south as you can go in Melbourne - it wasn't just the north and north-east.
Further edit: Here's some better information.
