GSNZ Otago branch talk
Discovering and cataloguing previously undocumented Otago and Southland earthquakes, 1855-1929
Jamie Gurney, GNS National Seismic Hazard Model Contractor
Seismicity in the Otago and Southland regions during the 19th, and first four decades of the 20th, centuries is poorly documented in published catalogues and scientific literature. Using newspapers and contemporary felt reports, a more complete database of felt historical earthquakes has been constructed, potentially increasing the continuous record of known seismicity in the two regions from 85-90 years to approximately 160 years. Although defining the seismic parameters for these earlier earthquakes poses a significant challenge, the addition of 75 years of previously unknown seismicity may assist evaluation of existing seismic hazard assessments
