Taupō Rift termination faults
Fault zone in New Zealand
The seismically active southern end of the Taupō Rift beyond Mount Ruapehu has a number of mainly east to west orientated termination faults where the western wall Raurimu Fault and eastern wall Rangipo Fault (Desert Road Fault) terminate in the Ruapehu Graben, of the central North Island of New Zealand.[2] In a multi-fault rupture event there is the potential for the earthquake being of Mw7.1 magnitude.[1]
The faults can be classified as belonging to three normal fault sets:[3]
- Ruapehu Graben NNE‐trending faults
- Raurimu Fault - see separate article
- Rangipo Fault (Desert Road Fault) - see separate article
- Mostly uncharacterised faults under Mount Ruapehu
- Ohakune‐Raetihi fault set that is 15 km (9.3 mi) wide of E‐W to ESE‐WNW‐trending faults[3]
- Ohakune Fault
- Raetihi North and South faults
- Waipuna Fault
- Oruakukuru Fault
- Rangiahu Fault
- Maketu Stream Fault (Maketu Trace)
- Karioi fault set that is 24 km (15 mi) wide of NE‐trending faults[3]
- Karioi Fault
- Wahianoa Fault
- Snowgrass Fault
- Shawcroft Road Fault
- Moawhango Fault
