My site got record hits the day of our earthquake. 100 times normal. Of course all the hits to Natural Resources Canada (which does USGS type stuff) knocked them offline, so people that got to my page saw "no earthquakes in last 30 days"... I was able to put up some text about the quake and the NRC page being down, but not after a few hundred people moved on.
The blogger video was cool, you can see the fear in his eyes. I'll admit the one quake I went thru was pretty scary,
Days like this causes traffic to my site to soar to the earthquake page.
