8:50am. The stream of recent north and east Australia Plate boundary earthquakes continues, with this morning’s of a higher magnitude affecting New Zealand:

Source: GeoNet. Note the numerous local aftershakes quickly triggered across north and central NZ.

This seismic shunting of Aotearoa-NZ was from a magnitude 5.4 subduction slab quake, deep to our north:

Tonga Trench ridge magnitude 5.4 quake - GIM 030811

Its effect in Waikato was pronounced:

..connecting with Mount Ruapehu:

The impact on Canterbury seismographs was also pronounced, with all? local drums recording the deep Tonga Trench 5.4 quake (at the 1.5-hour-ago mark, bottom left corner) here:

Note especially how the critical Inchbonnie (Alpine fault) drum has been so busy over the past 48 hours that it appears to have been driven off-line – OUT OF SERVICE !!!

The same, quite strangely, could recently be said of the seismographs far to New Zealand’s south:

Mt Erebus volcano MAC seismograph - MEVO 310711

Mount Erebus Volcano Observatory MAC Seismic Activity – did the data transmission batteries run down, lacking solar power in winter, or have dramatic earthquakes upset this equipment and its seismic records?
Note parallel regional quake activity (magnitude + depth):
Sunday July 31 2011, 23:38:57 UTC near the north coast of Papua New Guinea 6.8 16.8
Sunday July 31 2011, 14:34:50 UTC Vanuatu region 6.2 23.1

New Zealand’s central North Island, south-west to north-east, active subduction zone is properly lit up by recent quakes.

It is just a matter of time until our next catastrophic earthquake.
