Edit: Extent of earthquake – no power first night and everything at the airport delayed. Felt like a third world country. Convenience stores were letting in one customer at a time to prevent looting, which meant 2 hour+ lines. Had to scrounge up a dinner in the darkened streeks of Wikiki from chinese foodstands: bowl of rice, a banana and some japanese brownies. Otherwise, things were fine after the power came back, the next night.
Water for snorkling was murky. Volcanos park smells like sulfer; Mordor, etc. Wikiki Beach felt like Lost in Translation 50% Japanese. Thats it.
