Seismological and Hydrogeological Controls on New Zealand-Wide Groundwater Level Changes Induced by the 2016 M_w 7.8 Kaikōura Earthquake

Figure 1

Spatial distribution of the hydrological and seismic dataset that recorded the 2016 M_w 7.8 Kaikōura earthquake. (a) Kaikōura earthquake focal mechanism [5] and surface rupture zone [13]. (b) 306 seismic stations (strong motion and broadband) recorded the Kaikōura earthquake. (c) Water level data were collected from 433 monitoring wells, and rainfall and atmospheric pressure were collected from 65 climate stations, which spanned the earthquake interval. Monitoring wells in Cromwell Gorge are highlighted differently.
