Since it's the week over Christmas, I'm not going to fulfill my Review / Research cycle. I'll start that again in the New Year. In the meantime, a cool research site is Australian Geoscience. If anyone is curious about Australian natural disasters, their commonality, and historical examples, well, take a look. If not, no biggie. Just comment with what your favorite natural disaster is. Whether by favourite you mean 'most frightening', 'most awe-inspiring', or any other 'most' you care to apply.
My favorite are tornadoes and cyclones. I keep dreaming of those. It's one of the few natural disasters that you can follow and watch.
