Okay..I have to ask this question...I know California just had an earthquake and from my years of observation..everytime there's an earthquake that starts at one point it causes a few months down the road an earthquake somewhere else (for example..just example..if in January there was an earthquake in Turkey, then later in May earthquake in Chile )..I know seismetologists has said things aren't related but I have noticed that once one earthquake starts it triggers another earthquake somewhere so I don't care what seismetologist says.
In Japan I know that there are "undercover" places when alarm sounds...does Hawaii have anything that sounds alarm? Tsunami warnings ,etc? I am not frightened or losing sleep but we will be in Hawaii for three weeks in May, and just want to have knowlege and be alarmed.. Things happen and we can't always prevent it..
I treat this like there are sharks in ocean but doesn't mean you encounter them...but still want to have knowledge in event something happens...
