1 5th International Workshop on Collapse Calderas December 7-11, 2014, Taupo, New Zealand Caldera Volcanism and Society Second Circular & Registration Information Conveners: Jim Cole Department of Geological Sciences, University of Canterbury, Christchurch, New Zealand Nico Fournier GNS Science, Wairakei Research Centre, Taupo, New Zealand

2 Collapse Calderas Workshop The IAVCEI Commission on Collapse Calderas (CCC) was created in March 2008 to have a wider and deeper understanding on calderas. The idea to file for a commission emerged in 2005, during a workshop on Caldera Volcanism, at which the Collapse Calderas Work Group was formed. The CCC ( includes a wide spectrum of disciplines, such as caldera geology, geophysics, mathematical and analogue modelling, subcaldera magma chamber processes, volcanic hazard and risk management, economic benefits and environmental research. Thus, it promotes interdisciplinary interaction to help solve the many questions regarding the formation of collapse calderas, their evolution, and their potential effect on society. Successful workshops are organised on regular basis, and have been previously held at Tenerife, Canarias (2005), Mexican Volcanic Belt (2008), Reunion Island (2010) and Bolsena, Italy (2012). Date The 5th Workshop on Collapse Calderas is scheduled for December 7-11, 2014 in Taupo, New Zealand. These dates have been chosen to precede the American Geophysical Union (AGU) Fall Meeting in San Francisco, which is scheduled for December 15-19, Venue Taupo is located on the shore of Lake Taupo, at the southern end of the central Taupo Volcanic Zone (TVZ), the most frequently active and productive Quaternary silicic system on Earth. Central TVZ is characterised by intense rhyolitic volcanism associated with 8 calderas and caldera complexes. The most recent ignimbrite eruption is from Taupo caldera, in the north eastern part of Lake Taupo in 232AD. Unrest at TVZ is closely monitored by GeoNet, a national geohazards monitoring programme, which is a collaborative operation between the NZ Earthquake Commission (EQC) and GNS Science. TVZ is also the site of numerous thermal areas, many of which are the sites of commercial geothermal fields. The relationship between Caldera Volcanoes and Society (including unrest and resources related to calderas) will be a focus of this Workshop. The workshop will be held at the Millennium Hotel on the lakefront, 5 minutes drive from town. Overseas participants to the Workshop will need to fly into Auckland International Airport, and either fly on to Taupo by Air New Zealand Link (45 minutes) or go by road (bus or rental car) to Taupo (approx 4 hours). The Workshop will start and finish in Taupo. Workshop outline The workshop, like previous meetings, will be devoted to understanding many different aspects of calderas. There will be four broad themes: 1. Physical Setting and Volcanology (including: volcano-tectonic setting, formation, structure, deposits; eruption processes; subsidence): 2. Magma processes (including: anatomy of plutonic magma systems; plutonic/volcanic relationships); 3. Resources related to calderas (including: geothermal activity; mineralisation; water; environmental issues); 4. Unrest (including: timescales of caldera formation; monitoring techniques; the effects of eruptions on infrastructure). The workshop will begin with an overview field trip of calderas of the Taupo Volcanic Zone on Sunday, December 7, which will be combined with a final field trip for the accompanying 3 rd International Course on Collapse Calderas. Presentations will consist of 2 full days of scientific meeting, with oral and poster sessions, and 2 further days of field trip, one of which will be based around Lake Taupo, and concentrate on the 232AD eruption, and the other around Lake Rotorua, concentrating on geothermal activity and calderas. Thematic discussions are planned at regular intervals during both the presentations, and field trips.

The largest group of Abstracts is in Theme 1 (Physical Setting and Volcanology including volcano-tectonic setting, formation, structure, deposits, eruption processes and subsidence) and will be divided into 3 sub- Themes: 1. Structure & Processes (both large and small scale); 2. Deposits; 3. Taupo Volcanic Zone. This will occupy the whole of the first day of papers in the Workshop. Potential contributors include: Shan de Silva, Darren Gravley, Tetsuo Kobayashi, Nobuo Geshi, Karoly Nemeth and Steve Self. Themes 2 (Magma Processes - including anatomy of plutonic-magma systems and plutonic/volcanic relationships), 3 (Resources related to calderas including geothermal activity, mineralisation, water and environmental issues) and 4 (Unrest including timescales of caldera formation, monitoring techniques, the effects of

4 eruptions on infrastructure) will be held on the second day. Potential contributors to Theme 2 include Peter Lipman, Margaret Mangan, and Phil Shane; to Theme 3 include Ted Bertrand, Isabelle Chambefort and Jim Cole, and to Theme 4 include Riccardo Di Lorenzo, Nico Fournier, Sally Potter and Tom Wilson. Field Trips Sunday 7 December - Field Trip 1 (combined Workshop & Course) Calderas of the Taupo Volcanic Zone (Leaders: Darren Gravley & Jim Cole) This will be an overview of caldera structures in central TVZ, including the relationship between volcanism and magmatism and volcanism and tectonics; evidence for flare-ups (particular periods of intense ignimbrite eruptions and accompanying caldera collapse), and geothermal activity associated with calderas. Wednesday 10 December - Field Trip 2 (Workshop only) Taupo Volcano (Leaders: Geoff Kilgour; Mike Rosenberg; Nico Fournier) This will be an overview of Taupo Volcano, including evidence for the structure of the area; its volcanic history (with a detailed study of the 233AD Taupo eruption, including post eruption sedimentation); styles of eruption; deposits; geochemical variation within the Taupo magmatic system; relationship with extensional tectonics of the Taupo Volcanic Zone, and an overview of volcano monitoring at Taupo Volcano. Thursday 11 December - Field Trip 3 (Workshop only) Northern TVZ calderas; aspects of hazards and geothermal systems (Leaders: Brad Scott; Brian Carey) This trip will emphasise our understanding of the potential hazards associated with calderas of northern TVZ (Rotorua, Okataina and Reporoa), using examples from recent eruptive and earthquake events, but also the secondary aspects of caldera systems - geothermal systems. Geothermal systems are important to New Zealand for a variety of reasons, including its cultural history, tourism and energy use. The trip will include a visit to Rotorua city and a geothermal field in central TVZ. All trips will be full day bus trips, to and from the Course/Workshop venue in Taupo, with comparatively little walking. Icebreaker & Dinner There will be a welcome Icebreaker at the Millennium Hotel beginning at 6pm on Saturday 6 December, and a dinner is now planned for the evening of Tuesday 9 December (venue to be arranged). Costs Registration fee for the Workshop: NZ$450 Includes attendance at the 2-day Workshop, 3-days of field trips, icebreaker function and Workshop dinner.
