That quake was just 38 km (24 miles) from Mount Taupo.
Taupo Volcanic Zone
the energy went south, but looking at the locations of the aftershocks, they went north . Ying/Yang ?
Any volcanoes gona blow up on the 21st.

Re the magnitudes are you sure it is GeoNet that are right. Whilst EMSC and USGS are often in unison, GFZ Potsdam are not yet all three say Mag 6.3. GeoNet is the voice in the wilderness.
Seeing as how an M5.77 ML is also around the same in Mw if the memory serves right, then that is a massive potential difference. Call that 5.8 and then it is ~5.6 times stronger for the M6.3. This a BIG margin.
To make that a little clearer think of it in kilotons of TNT
GeoNet 5.7 = 7.56 kTons
USGS et al 6.3 = 42.5 kTons

interesting how in the historical data there is a clearly defined North/South Fault running up from Pratt Seamount, although you can't see anything on the seabed
I used ANSS circular search, so you end up with a big circle of quakes on the maps, probably should use a closed polygon so it fits the rectangular map better, but circles are easier. and you don't know the borders required until you see the data mapped anyway
I don't believe this one is an aftershock of the 9.0, although they can go on for years, its way out on the Pacific Plate
I may have been wrong about the 7.3 the other day not being an aftershock of the 9.0.
EVALUATION A DESTRUCTIVE TSUNAMI WAS NOT GENERATED BASED ON EARTHQUAKE AND HISTORICAL TSUNAMI DATA. THIS EARTHQUAKE IS LOCATED TOO DEEP INSIDE THE EARTH TO GENERATE A TSUNAMI IN THE INDIAN OCEAN.
