The Hawaiian Department of Transportation (DOT) has also urged all shipping agents and shipping companies to get their ships out of port as soon as possible, according to local Hawaiian news agency.
We are urging people not to panic, said the DOT spokeswoman, Tammy Mori.
It's important that those in low-lying areas can get to higher ground. We want to remind people that they have five hours to evacuate after the alarms sound.
