earthquake

at 5:32am (by my clock) 10 aug 2009, where i live in australia, there was a deep underground earthquake. a seismic interference or incurrance (or whatever word is meant to describe something like that). i wonder if these things are measured. australia is smack bang in the middle of the most stable tectonic plate on planet. there's no rifts, no fault lines, no volcanic activity. not another plate to rub against.

i wonder if it even occurs to people to wonder what is going on...
