I've gone to the USGS SITE and the 7.7 was at the deepest level and furthest from Suva, the capital of Fiji. the 7.5 was a lot closer to the surface and a lot closer to Suva.
I have not heard at all from my relatives. I have emails in to them. . . several days ago and today after getting the post on the quakes from USGS and the net.
Thanks for your prayers and concern.
Phones are down, I take it.
Thought about asking some Freepers with ham radios to check it out? I remember some of them on threads about that large fire in Arizona.
I do not recall their screen names, though.
