Ocimnet.com - A massive earthquake off the coast of Japan Thursday caused the Pacific Tsunami Warning Center to issue a tsunami warning for Hawaii.
The Warning Center originally issued a watch for Hawaii, but changed it to a warning at 9:31 p.m.
The projected arrival time for the first tsunami wave in Hawaii has been revised to 3:07 a.m., according to the City and County of Honolulu's Department of Emergency Management.
"A tsunami has been generated that could cause damage along coastlines of all islands in the state of Hawaii," the Warning Center said, in a statement.
A tsunami is a series of long ocean waves. Each wave crest can last five to 15 minutes and cause extensive flooding of coastal areas. The danger can last for several hours after the initial wave as subsequent waves arrive.
The 8.9-magnitude earthquake hit the coast of Honshu, Japan at 7:46 p.m. HST. It struck about 230 miles northeast of Tokyo.
