Active faulting near Taupo

Authors


Abstract

The only confirmed fault displacement in New Zealand since that accompanying the 1968 Inangahua Earthquake was observed on June 23 and 24, 1983, 4 km west of Taupo in the Taupo Volcanic Zone, central North Island (Figure 1). Normal displacement occurred on the late Quaternary Kaiapo fault, previously active in 1922, when almost 1 m of normal fault displacement was observed [Grange, 1932], The Kaiapo Fault is one of a number of north-east trending normal faults that constitute the active Taupo Fault Belt [Grindley, 1961], Current extension rates up to 7 mm per year have been calculated from geodetic observations [Sissons, 1979] across the northern part of the Taupo Volcanic Zone.
