2015 earthquake density isolines (earthquake/km^2) for Ngatamariki and Rotokawa geothermal fields including all matched filter detections. The green triangle indicates the area within which most seismicity has occurred since 2012. The maximum density (located in Rotokawa) is 829 events per square kilometer. Contour intervals are 50 earthquakes per km^2. Locations were calculated using NonLinLoc.
