    SUBJECT - TSUNAMI WARNING
    
    A TSUNAMI WARNING IS ISSUED FOR THE STATE OF HAWAII EFFECTIVE AT
    0709 PM HST.  THIS UPGRADE IS DUE TO THE SEA LEVEL READINGS
    RECEIVED AND THE RESULTING CHANGE IN THE HAWAII TSUNAMI
    FORECAST.
    
    AN EARTHQUAKE HAS OCCURRED WITH THESE PRELIMINARY PARAMETERS
    
       ORIGIN TIME - 0504 PM HST 27 OCT 2012

    EVALUATION
    
     A TSUNAMI HAS BEEN GENERATED THAT COULD CAUSE DAMAGE ALONG
     COASTLINES OF ALL ISLANDS IN THE STATE OF HAWAII. URGENT ACTION
     SHOULD BE TAKEN TO PROTECT LIVES AND PROPERTY.
    
     A TSUNAMI IS A SERIES OF LONG OCEAN WAVES. EACH INDIVIDUAL WAVE
     CREST CAN LAST 5 TO 15 MINUTES OR MORE AND EXTENSIVELY FLOOD
     COASTAL AREAS. THE DANGER CAN CONTINUE FOR MANY HOURS AFTER THE
     INITIAL WAVE AS SUBSEQUENT WAVES ARRIVE. TSUNAMI WAVE HEIGHTS
     CANNOT BE PREDICTED AND THE FIRST WAVE MAY NOT BE THE LARGEST.
     TSUNAMI WAVES EFFICIENTLY WRAP AROUND ISLANDS. ALL SHORES ARE AT
     RISK NO MATTER WHICH DIRECTION THEY FACE. THE TROUGH OF A TSUNAMI
     WAVE MAY TEMPORARILY EXPOSE THE SEAFLOOR BUT THE AREA WILL
     QUICKLY FLOOD AGAIN. EXTREMELY STRONG AND UNUSUAL NEARSHORE
     CURRENTS CAN ACCOMPANY A TSUNAMI. DEBRIS PICKED UP AND CARRIED
     BY A TSUNAMI AMPLIFIES ITS DESTRUCTIVE POWER. SIMULTANEOUS HIGH
     TIDES OR HIGH SURF CAN SIGNIFICANTLY INCREASE THE TSUNAMI HAZARD.
    
     THE ESTIMATED ARRIVAL TIME IN HAWAII OF THE FIRST TSUNAMI WAVE IS
    
                         1028 PM HST SAT 27 OCT 2012
    
    MESSAGES WILL BE ISSUED HOURLY OR SOONER AS CONDITIONS WARRANT.

    Hopefully too many people didn't get hurt in the panic.

    Looking at the evacuation zones it would have been as trivial as walking a couple of blocks to get away from the ocean in most cases. I realize people would want to remove their cars from the evacuation zone "just in case", but it seemed like there were a lot more people running a lot further away than they needed to ... even if a big wave hit.

    I suppose too many people have seen disaster movies and footage from Japan in 2011.
