How to build and destroy a stratovolcano – Mts. Ruapehu and Taranaki

Leaders: Anke Zernack, Shane Cronin, Jon Procter, Shannen Mills

Duration: 5 days (4 nights) 25-29 January 2023

Level of fitness required: light to medium (mostly road and beach outcrops but some walking over uneven terrain might be required)

SummaryStarting in New Plymouth, this field trip focuses on the long-term volcanic histories of New Zealand’s most prominent andesite stratovolcanoes, Mounts Taranaki, Ruapehu and Tongariro. We will explore the range of lithofacies produced by repeated edifice growth and catastrophic, debris-avalanche generating failures along with other landscape-shaping events recorded in the extensive volcaniclastic ring plains around these volcanic centres. The range of internal and external factors that control the nature of ring-plain accumulation and evolution of volcanic landscapes will be investigated, including the influence of the 232 CE Taupo eruption and its widespread products. This will be complemented by exposures of primary volcanic deposits that built the modern-day edifices to provide a holistic picture of the nature, frequency and magnitude of hazards from this type of volcano.

Participants will gain a comprehensive understanding of stratovolcano growth and collapse processes, and the spectrum of produced volcanic and sedimentary deposits and landscape features, visiting some of the best-exposed, most complete examples of volcaniclastic ring-plain successions in the world. Apart from outstanding geology and natural beauty, this trip also offers a taste of unique Kiwi outdoor, culinary and cultural experiences, including dinners at a vineyard, brewery and marae (Māori meeting grounds), swimming at Taranaki’s beautiful black-sand beaches, white water rafting down the Tongariro River and a ride in the Sky Waka gondola at Mt. Ruapehu with spectacular views across the world-heritage-listed mountain area.

Cost: NZD1,000 pp. Includes transport from New Plymouth to Rotorua in mini-vans, 4 nights’ shared motel accommodation (2-3 people per room, single occupancy can be arranged at additional cost) with breakfast, packed lunches for all 5 days, vineyard dinner, marae dinner and cultural experience, Tongariro River white water rafting, Sky Waka Gondola/Mt. Ruapehu, printed field guide. Not included: dinner drinks, dinner for 2 nights and additional snacks.
