The Pacific Tsunami Warning Center in Hawaii has widened its tsunami warning to include Hawaii and the rest of the Pacific Ocean, while a watch notice was issued for west coast of the U.S.
Sirens were sounded in Honolulu shortly after the warning was issued Thursday at 9:31 p.m. Haiwaii time. The warning follows a massive earthquake that has struck off the northeastern coast of Japan. It says the estimated earliest arrival in Hawaii of the first tsunami wave is 2:59 a.m. local time time Friday (7:59 a.m. ET).
"A tsunami has been generated that could cause damage along the coastlines of all islands in the state of Hawaii," the Pacific Tsunami Warning Center's bulletin said. "Urgent action should be taken to protect lives and property."
