Both types of natural events come in different sizes and shapes. Evidently our West Coast brethren have been belittling the 5.8 quake that hit the East Coast yesterday. Once folks in New York and Washington DC figured out that we were not under attack and that it was an earthquake, it became for most merely an inconvenience. It spread a great distance north from its origin in a small town in Virginia.
Please note that no one on the East Coast has been trained to "drop, cover and hold" for an earthquake. It's doubtful that you could keep anyone in Manhattan working inside a high rise when they remember 9/11.
This weekend, the East Coast is looking at a plausible second event this week and making Hurricane Irene preparations.
If you're a business located on the East Coast, this ComputerWorld article titled "Hurricane Earl: Tips to Batten Down IT" from last fall might be of interest. The advice in it from me and others is as good now as it was then.
