An estimated 7.6-magnitude earthquake in Costa Rica has triggered tsunami warnings for the Pacific coasts of Costa Rica, Panama, Nicaragua, El Salvador, Honduras, Mexico, Colombia, Ecuador, Guatemala and Peru.
A warning means "a tsunami is imminent and that coastal locations in the warned area should prepare for flooding," according to the National Oceanic and Atmospheric Administration.
A slightly less ominous "tsunami watch" has been issued for Chile.
According to NOAA's Tsunami.gov website, "an evaluation of the Pacific-wide tsunami threat is underway and there is a possibility that Hawaii could be elevated to a watch or warning status."
There's no word yet on the situation in Costa Rica.
