There was z 6.0 aftershock an hour later, and a 6.9 just a little while ago, a little ways away from the initial epicenter. Also a series of strong 6.0+ quakes around New Zealand this morning.

It appears there are also a rash of volcanoes going active now as well. A few up here, a couple in west-central South America, and Mauna Loa appears to be awakening. All this geologic activity at once, and right at the solar peak, makes one consider cause and effect perhaps?
