From our latest Hawaii story: "The island of Kauai was expected to be the first hit in Hawaii because the tsunami was advancing from the west and would likely take 20 to 30 minutes to cross the entire state"

"So far no waves," Lorilee Crisostomo told Reuters by telephone from Guam, roughly an hour after the tsunami was first due, though forecasters set a four-hour window in which a wave could hit the island.

None of those places are on tsunami alert

Electric Power Development (J-Power) also halted operations of its Isogo thermal power plant in Yokohama, Jiji reported"
