Predicted zones for the next 8.0 or larger. There have been so many events in the 6.5
to 7.5 range that there are not many preferred locations.
Note that a major seismic event inside any of the four purple triangles (or outside
them, for that matter) will have tsunami consequences for Papua-New Guinea,
Australia and island neighbors such as Vanuatu and Tonga.
We'd certainly advise a mutual assistance arrangement and
cooperative management of sensor networks. Neither
seismic nor water waves care about national boundaries or
intra-national divisions.
