Researchers discover deep, hidden faults in New Zealand's Southland, challenging seismic risk models.

Researchers from the University of Otago found hidden faults and deep earthquakes up to 40km deep in Southland, New Zealand, a region with low seismic activity. The seismically active crust extends twice the average depth, which could improve models predicting future earthquake likelihood and strength. The research, funded by the Natural Hazards Commission, aims to better understand seismic risks in areas like Otago and Auckland.
