There are some specific areas in the Waikato region that contain active earthquake fault lines which are more likely to experience earthquake activity. @Lynley - the general evolution of the earthquake sequence is eastward, thus any map of probable fault lines delineated in the past few months will be of little (if any) use. If a fault has moved in the last 5,000 years, it is considered a potential source of damaging earthquakes to any community within a radius of 50 km from the epicentre. Your map is next to useless for us who are living through this. Please place a link on this page of the fault lines map, a document .pdf file...would be nice.

But if the earthquake is big enough (more than about magnitude 7) and shallow enough, the movement on the fault come right up to the ground surface, fracturing (faulting) and buckling (folding) the surface of the ground along the line of the fault by up to several metres. This map effectively shows the areas where future earthquakes are most likely. Satalites using thermal etc to detect earthquakes upto 4 days b4 it happens, due to the huge amount of energy released from plate movement. It’s the "on-land" boundary of the Pacific and Australian Plates. Many smaller faults remain undiscovered until they generate an earthquake. The Alpine Fault, which runs for about 600km up the spine of the South Island, is one of the world’s major geological features.
