Best Interactive Map Going of the Christchurch-Area (and North) Quakes

The best interactive map going of today's NZ quakes is here. The biggest shallow quake was near Waiau, with numerous, deeper aftershocks near the Kaikoura coast.

Most of the recent Christchurch quakes, since 2010, have been in an arc, like a diabolic smile, running west to SW to SE to east of town, but this quake was NNE of town, in a previously-quiet area near the Alpine Fault.

That whole elliptical chunk of land, the northern part of the Canterbury Plain, has been rotating in violent counterclockwise jerks since 2010. It was just about inevitable that the fault on the north side would have to break too.
