    I live on a boat right here in San Pedro, CA and cannot feel when an earthquake happens. I heard absolutely NO WARNING OF ANY KIND. Where the U.S. Geological Survey got their information that a tsunami warning was issued, I don’t know, but I consider this a major problem in my life. It’s now 6 hours after the earthquake hit so, fortunately, I’m safe…..but, gee whiz, I certainly am not at all comfortable at all with a non-existent warning system. Can anyone tell me what organization I can call regarding this lack of warning to those of us on the coast?
