State officials in Hawaii have activated their emergency response plans to prepare for a possible tsunami caused by the massive earthquake in Chile, an official said Saturday.
The Pacific Tsunami Warning Center issued a tsunami warning – its highest alert – for Hawaii, where incoming waves could cause damage along the coastlines across the island chain. A warning was also in effect for Guam, American Samoa and dozens of other Pacific islands.
The first waves were expected to arrive in Hawaii at 11:19 a.m. Saturday (4:19 p.m. EST).
