All the mid-conference field trips are full. If you did not sign up to a mid-conference field trip and would like to be added to the waitlist for one, please email

Fully booked - Taupō supervolcano: An overview

Leaders: Simon Barker, Finn Illsley Kemp, El Mestel, Colin Wilson, Graham Leonard, Michael Rosenberg

Cost: $30 NZD per person

Taupō volcano is the site of the most recent supereruption on Earth which ejected >530 km3 of magma at ~25.4 ka. It has also produced ~25 rhyolitic eruptions during the Holocene, including the extremely violent 232 AD "Taupō eruption". This day trip will give an overview of the volcanic and structural features of Taupō caldera and we will discuss eruptive/unrest history, the range in eruption sizes/frequency and outline the evolution of the volcano. We will visit key locations to showcase the different aspects of Taupō's history, view eruptive deposits and geothermal steam fields, and discuss ongoing monitoring and recent unrest episodes. This trip is intended as an overview of Taupō with easily accessible areas to match all levels of fitness and includes a 2 hour chartered boat trip out on the lake. A more detailed trip looking at eruptive stratigraphy and ignimbrites is also offered as a 5 day post-conference trip for those interested.

Fully booked - Tarawera 1886: a basaltic Plinian eruption

Leaders: Rebecca Carey, James White, Hannah Moore

Cost: $70 NZD per person

The most recent Plinian eruption in New Zealand occurred on 10th June 1886 during the Tarawera eruption. The impacts of this event were significant to local Māori who lost almost 120 people. This fieldtrip will examine aspects of the 17 km long fissure from this violent basaltic eruption, examining the range of phreatomagmatic (interaction between basaltic magma and a pre-existing hydrothermal system at Waimungu) through to magmatic phases. Unique, ultra-proximal facies are extremely well-exposed due to the fissure slicing through pre-existing rhyolite lava domes. This fieldtrip will explore both the physical science aspects of this complex eruption, along with indigenous (local iwi) knowledge of the processes and impacts of volcanic eruptions. 

Fully booked - Geothermal development in an active volcanic system

Leaders: Isabelle Chambefort, Anya Seward

Cost: $40 NZD per person

New Zealand has a long history of geothermal energy production from individual fields across the Taupō Volcanic Zone. This day trip will explore the location, energy potential, and impacts of geothermal energy and the broader renewable energy system in New Zealand. By visiting one of the geothermal fields close to Rotorua, we will delve into the management of the resource and current plans for further development. We will then use this visit to connect indigenous knowledge, concerns, and considerations for how the resource is managed sustainably. We will then consider the next stage of new technology and consider the challenges and benefits of extracting super-critical fluids.

Fully booked - Northern Taupo Volcanic Zone Caldera volcanism: volcano-tectonic interactions at the caldera margin

Leaders: Brad Scott, Pilar Villamor

Cost: $15 NZD per person

The northern portion of the Taupo Volcanic Zone is occupied by the Rotorua, and Ōkataina Volcanic Centres set within the active Taupō rift, where closely spaced normal faults accommodate extension. This area has been the subject of interest for assessing the interactions between tectonism, volcanism and geothermal activity. On this field trip, an overview will be provided of the Ōkataina and Rotorua Volcanic Centres and the surrounding area. Using roadside stops and sweeping lookout locations, we will assess the geomorphology of the region and explain the close connection between fault rupture and volcanic eruptions, in particular, the feedback between the two processes. During the trip, we will encounter a wide range of eruption styles from extrusive, rhyolite domes through to violent, caldera-forming events.

Fully booked - Social and indigenous impacts of volcanic eruptions

Leaders: Geoff Kilgour, Sally Potter

Cost: $15 NZD per person

Whakatāne is medium-sized New Zealand town with a population of ~40,000 people. This coastal town is situated on the eastern edge of the Taupo Volcanic Zone and had been the launching point for Whakaari/White Island tour operations. Whakaari is located ~50 km from Whakatane and boat trips (along with helicopter tours) at the time took hundreds of people daily to the visit this active volcano. Due to the popularity of the tour, many of Whakatane’s businesses relied on this tourism income to operate. This was also an important business for Ngati Awa, the local iwi (Maori tribe), who employed many local Maori and provided an opportunity for them to explain the importance of the volcano to their culture. On 9th December 2019, an eruption occurred that resulted 22 fatalities, 25 injured and shut down all tourism operations to the island. This field trip will examine the societal impacts of volcanic eruptions and the recovery that has taken place since.
