A warning system that monitors the Pacific Basin for activity that can set off a tsunami is already in place, according to the National Oceanic and Atmospheric Association. The system is operated via two centers — one in Alaska and another in Hawaii.
If activity that suggests a tsunami is forming is detected, NOAA issues a warning for coastal communities where there is a potential for impact.
