HONOLULU (AP) — David Sun-Miyashiro was at home on the 31st floor of a Honolulu apartment building, high above danger, when his phone alerted him to a possible tsunami from a massive earthquake far across the Pacific Ocean. With plenty of time to spare before any surging waters might possibly reach Hawaii, he did something he probably wouldn't have done in a more urgent scenario: He got in his car to go pick up his father, who would be needing a ride to the airport later. He didn't get far.
