[quote=Anonymous][quote=Anonymous]How vulnerable is Hawaii to earthquake/tsunami destruction?[/quote]

Tsunamis are the #1 natural disaster in Hawaii.  Fortunately, the Pacific Tsunami Warning Center does a good job, so now, it is unlikely for a Tsunami from a distant earthquake to surprise Hawaii like happened in 1946 (and other times).  Local earthquakes are somewhat more problematic.  They can be observed, located, and classified quickly, but the big local earthquake (probably on the Big Island) can knock out power, which can present problems.  However, Hawaii Civil defense is prepared for that.  In addition, most of the *Big* (tsunami generating) earthquakes are on the eastern edge of the Big Island, and that will direct the Tsunami away from the other islands (there will be a hazard and warning, but the Tsunami will not be huge in Waikiki, for example).

The scenario that scares some scientists there is a large earthquake on the western side of the Big Island, which can create a large tsunami directed towards the other islands.  There would be about 25-40 minutes, which will not be enough time to evacuate Waikiki, for example.
