THERE HAS BEEN NO MAJOR TSUNAMI OBSERVED NEAR THE EPICENTER.
THERE WAS HOWEVER A SMALL TSUNAMI OBSERVED ON THE COCOS TIDE GAGE. WARNING... THIS EARTHQUAKE HAS THE POTENTIAL TO GENERATE A WIDELY DESTRUCTIVE TSUNAMI IN THE OCEAN OR SEAS NEAR THE EARTHQUAKE. AUTHORITIES IN THOSE REGIONS SHOULD BE AWARE OF THIS POSSIBILITY AND TAKE IMMEDIATE ACTION. THIS ACTION SHOULD INCLUDE EVACUATION OF COASTS WITHIN A THOUSAND KILOMETERS OF THE EPICENTER AND CLOSE MONITORING TO DETERMINE THE NEED FOR EVACUATION FURTHER AWAY. ...
THIS CENTER DOES NOT HAVE SEA LEVEL GAUGES OUTSIDE THE PACIFIC SO WILL NOT BE ABLE TO DETECT OR MEASURE A TSUNAMI IF ONE WAS GENERATED. AUTHORITIES CAN ASSUME THE DANGER HAS PASSED IF NO TSUNAMI WAVES ARE OBSERVED IN THE REGION NEAR THE EPICENTER WITHIN THREE HOURS OF THE EARTHQUAKE.

This is an example of how tsunami prediction is basically impossible without specific sensor buoys...an 8.7 is a really truly big quake and quakes of that size have generated HUGE tsunamis...
But many really big quakes, even underwater subduction quakes, don't generate a tsunami at all.
8.7 now confirmed. wow
