Having experienced the Ca. 89 quake I feel for them. It looks like a lot of bad damage in the news reports including some fatalities.

Almost any earthquake of 5.0 or greater does some type of damage. 7 and above tend to do a lot of damage. I've never been in an earthquake that I was aware of, although was driving in northern Mississippi during reported earthquake - but the roads were so bad I didn't know it had occurred until someone who was in a building at the time told me about the shaking.
Mississippi has never been know for the quality of its roads - or of their electric power providers. I worked with a guy who lived in northern Mississippi who bought the 24 volt battery plant (racks and all) when a small telephone exchange closed down. He had 24 volt volt lighting and 24 volt outlets in every room. He charged the batteries with a WinCharger (maybe two of them) he found in Oklahoma and had shipped to him - complete with the tower. This would have been the late '60's or maybe as late as 1970. They managed just fine with their locally produced power and had the battery bank sitting in the carport where it was protected from the weather. Not optimum in winter because lead-acid batteries lose 15% or more of their power when their temperature drops to 50F. Not sure how he worked around that - especially when the lows in winter were near or below freezing.
He was the guy who destroyed one of my electric linear actuators. He decorated for Halloween like some people decorate for Christmas - the fact that he was descended from a long line of funeral home operators might have had some bearing on that ;-) Anyway, he wanted to raise and lower the lid on a coffin so I offered the use of the 24 volt DC actuator. It was obviously designed for setting something ith no load on it because the specs had "Moving load: 20lb. Static load: 720lb." Patrick just read the biggest number and tried to move a large wooden coffin lid and the actuator died. He told me "I don't know what's wrong with it. It says it can handle 700 pounds." That's what happens when a shadetree mechanic doesn't understand the difference between "moving" and "static" loads.
