The city has opened its Emergency Operations Center at the Frank F. Fasi building where police, firefighters, and the mayor have assembled. 

“We’re looking at a potentially very serious event here,” said city Department of Emergency Management spokesman John Cummings. 

He said if the Pacific Tsunami Warning Center changes the tsunami watch to a warning then all residents in coastal inundation zones will have to leave. Those areas are mapped out in the phone book or at the Department of Emergency Management website. 

If there is a tsunami, the first waves should hit about Hawaii about 3:07 a.m., he said. 

Residents should be listening to the radio and watching TV for information and be preparing for an evacuation, he said.
