[Update 12:38 a.m.] Gerard Fryer, senior geophysicist at the Pacific Tsunami Warning Center was just on CNN International and put the magnitude of the quake into perspective - while at the same allaying much of the concern.
"A 7.7 is a big, hefty earthquake. It’s not something you can ignore," he said. But, he added, "this earthquake was partly under the island and mostly under shallow water."
"I think we have to be thankful it happened where it did . .. if that were a heavily populated area, it would have caused significant damage," he said. "It definitely would have done significant damage if it had been under a city."
