The good news is that having spent a portion of my life living on The Hayward Fault in No CA, and having lived through the 89 quake, one of the upsides is that disaster preparedness for earthquakes seems to be better documented and thought through than many other calamities. From bolting down houses to foundations to strapping water heaters, there exists a much better "to do" list than specific preparations for ice storms, power outages etc.
I have learned much more in the last 60 days on this site from the accounts in Seattle and MO regarding these scenarios than any other source.
Getting others to prepare is the same for eathquakes and ice storms... most don't. some do a little and a very few have a decent plan.
