Horizon Lines reported that the earthquake measuring magnitude 6.6, and several strong aftershocks including one measuring magnitude 5.8, that struck the Big Island of Hawaii on Sunday morning has not significantly impacted its operations. Inspections conducted Sunday found all cranes fully operational and minimal impacts to the Port of Honolulu. Power was restored late Sunday and a Horizon Lines vessel, the Horizon Pacific, made its normally scheduled port call and was successfully worked last night.
