This entertaining and easy-to-read guide to geological faults explains the processes behind their occurrence and the earth-quaking effects when they rupture. New Zealand has more than 150 active geological faults, and many of them move repeatedly setting off the 200+ earthquakes that are big enough to be felt each year. The ways that prehistoric earthquakes are investigated, and the benefits of tracking down past ruptures to preparing for future earth movements are explained. Nearly 100 superb aerial photographs and graphics illustrate the results of geological faults on the landscape, clarify the tectonic activities that create the disruption, and map the outcomes in different parts of New Zealand.
