tsunami warnings...

It's a good thing that people are warned well beforehand if a tsunami may be on its way.  However,  in the case of Hawaii, it seems like every time there's a warning, nothing happens.  Sure, you just never know the forces of nature, but there must be a better system of tsunami preparedness.  Just off the top of my head, a Halloween Party was cancelled in downtown Honolulu because of the tsunami warning last night.  I heard the sirens last night, but being in a building well over the 4 floors, I really wasn't concerned.  As I wrote before, nothing happened and I'm sure businesses lost of a ton of money last night...
