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

Figure 5

The relationship between earthquake-induced mean static stress changes () and water level changes. (a) Static stress-induced compressional stress changes. High areas of compressional stress changes include (i) Wellington and Canterbury and (ii) Marlborough. (b) Static stress-induced tensional stress changes. High areas of tensional stress changes include (i) Tasman.
