I lived in FL from 1979-1989. My home was hit by lightning more than once. The first time it killed my television and the second time we had to have the circuit breaker panel replaced. I never felt it was life threatening due to the way a house is grounded and I was fresh out of high school, we all felt bulletproof back then.
Today it’s a different story, I’m much older. I have to weigh the risks and rewards. What little research I’ve done has been all via internet, I have not spent any time in the library on this issue, but I might next week. Most voids that cause the ground to collapse occur over hundreds to millions of years. The voids that occur quickly due to water eating away the limestone will cause the ground to show settling before a collapse. I’m not concerned about settling, that’s why we have insurance. I’m concerned about the possibility of large, existing, voids that can foreshadow a sudden collapse. I want to test for those large existing voids.
All I asked of TV sales office is to allow me to test the lot (at my expense) before I give them a big check. They said no.
