I once saw a TV show called, “It Could Happen Tomorrow.”
The show mentioned one or two earthquake faults east of Las Vegas, and showed what would happen if one of them generated a major earthquake in the Las Vegas Valley.
Bottom line, a number of people dead and a great deal of property damage in a worse case scenario.
The cycles between large quakes are way beyond my understanding
the big talk about the soon coming BIG ONE...in California has been going on for so many years that I’m thinking it may be utter speculation
