Hi Cabe,
It is really a story of tragedy. You really saved your and the other familiy member's lives. Your curiosity did the job. Sometimes simple things can save lives as in your story. I am happy you had repaired the radio and now you are with us.
Unfortunately, we are week against natural events and have nothing to do. We have to learn to live with it. For tornados, you just have to find a safe place. Because tornados affect large fields, you can not live your home. For volcanoes, you can choose a safety distance for home. For earthquakes, you can choose a safety region to have a home. In my case, we live a region of first degree earthquakes happen. And my work place has built on a fault line. This is a wrong selection but it has made and no one is thinking to change this place because of the investment made already. Nonesense, but it is true. In my country, about 11 years ago, there happened two earthquakes with amplitude of 7.6 and 7.4. In the city, Izmir, where i live, there happened two eartquakes with amplitude of 5.9 and 5.9 in just one week and many others happened ove amplitude of 4.0 in that week.
So, first of first, choose a place far away from dangerous points, if you are unable to find one then prepare a safety place and try to be MacGyver
