Accumulating links and interpretation for earthquake M7.8 - 53km NNE of Amberley, New Zealand

I am accumulating some links and thoughts with respect to the earthquake M7.8 - 53km NNE of Amberley, New Zealand. Magnitude and depth were increasing as the seismologists reviewed the seismograms. The magnitude and depth (as long as it does not get much deeper) would be consistent a rupture on the Hope Fault. The location and to some degree the focal mechanism would be more consistent with one of the thrust faults further to the west. Reports are coming in that there is a tsunami that was [...]
