Large, but deep, m8.2 earthquake in the Pacific

There was an intense earthquake in the Pacific last night near Fiji.  It was rather deep, about 560km below the surface of the earth, and apparently did not cause any significant damage or create a tsunami.  Remember there are three major aspects to earthquake damage: intensity (magnitude), depth, and the surface soil characteristics.  The first two are the big factors; a 6.0 near the surface (10km deep) will cause much more damage than a 8.0 several hundred km deep even though the 8.0 releases a thousand times more energy!
