I just posted an entry about how there's been a massive earthquake in Chile, and that there would be a tsunami.

The wave just hit New Zealand. It was 3 metres tall.

It could get smaller, it could get bigger, it could stay the same. I'm hoping for the former. A >3m tsunami in Sydney would be terrible. It probably wouldn't get to our house, even more so because it's on a hill, but still, it'd wreck the CBD.
