It was a 6.6 magnitude with many aftershocks. Reuters is reporting:
There were no immediate reports of injuries, but there were scattered reports of damage and power outages were widespread.
“It was the biggest earthquake we’ve been through. It was pretty serious and we’ve lived in Tokyo for 11 years,” said Arthur Roberts, who lives 15 miles north of Hilo on Hawaii. “We heard that Kona community hospital suffered structural damage and is moving patients to another site.”
The Honolulu Advertiser reported on its Web site that Honolulu International Airport was closed, there were landslides in Hamakua and Kealakekua and major damage at Kona Hospital, the Honokaa Long-term Care Facility and the Royal Kona Resort.

Stuart Koyanagi, another geophysicist at the tsunami warning center, said the 6.6 magnitude earthquake was followed seven minutes later by a 5.8 magnitude temblor and by several smaller quakes. Seismologists warned of aftershocks through Monday.
Governor Lingle declared Hawaii a disaster.
