COT at the IAVCEI Scientific Assembly, Rotorua, New Zealand (30 Jan – 3 Feb 2023)
The last few days of January and the first few days of February 2023 – unfortunately coincided with a “weather bomb” that wreaked havoc on Auckland and other parts of northern North Island of New Zealand – saw the successful running of the international volcanology conference held in Rotorua under the auspices of IAVCEI (International Association of Volcanology and Chemistry of the Earth’s Interior).

The city centre was festooned with these flags and a public session “Volcanofest” occupied an entire day (Thursday 2 Feb) with volcano art and photography, experiments and game demonstrations, a Q & A panel, and a “meet a volcanologist” session for families and children.

It was a relief that the 2023 meeting finally went ahead with 860 in-person registrants and 203 virtual participants despite numerous problems with the wet weather and temporary closure of Auckland Airport that disrupted travel arrangements for scores of participants. Some participants “travelled” for nearly 5 days to get to the meeting and some never made it. Also, three of five mid-conference field trips were cancelled because of very heavy rain and poor visibility. Nevertheless, the conference was a great success and many felt it was the best they had ever attended. Refreshments and lunches provided throughout the conference were excellent, and the hosting staff and IT support staff were very helpful. Nine parallel sessions ran each day along with plenary sessions and two ECR plenary sessions. All sessions were on line and recorded. The fact that 51% of participants were early career researchers (ECRs) or students, helped make the conference very memorable and enjoyable.

CoT Pre-conference workshop and field trip
One of the pre-conference workshops was tephra-related: “From field apps to data repositories: improving tephra data discoverability, access, and workflows to support next generation research”, organised by Steven Kuehn, Kristi Wallace, Ellen Nelson, Andrei Kurbatov and Kerstin Lehnert. The workshop was the continuation of an ongoing project under the auspices of the CoT entitled “Community established best practice recommendations for tephra studies — from collection through analysis”, with a milestone (open access) paper by the group being published in Nature Scientific data last year. At the same time, a history of CoT was published (open access here) which highlighted the many developments and personalities of the tephra research spanning the last 60 years and beyond
For a field visit and a chance to try out the Strabo app for field data collection, David Lowe, Tehnuka Ilanko, and students Josh Hughes and Richard Melchert of the tephra Seismites Research Group at Waikato arranged an excursion to a tephra outcrop at a nearby pumice quarry on Okareka Loop Rd. For those interested their field guide has more details.

CoT sponsored two Tephrochronology related session at the Rotorua scientific assembly:
(1) “Tephrochronology, new methods and applications for chronostratigraphy and beyond” held on Monday 30 January, which was co-convened by Jenni Hopkins (Victoria University of Wellington), Britta Jensen (University of Alberta), and David Lowe (University of Waikato) with 18 papers (8 oral, 10 poster).

(2) “Constraining the tempo and magnitude of past highly explosive volcanism using tephrochronology: implications for volcanic hazard assessments” comprised 13 papers (4 oral, 9 posters) on Thursday 2 February, and was co-convened by Paul Albert (Swansea University), Karen Fontijn (Université libre de Bruxelles), Francesca Forni (University of Milan), Julie Belo (GEOMAR, Kiel) and Steffen Eisele (NTU, Singapore).

Both sessions were very well attended, comprising of excellent papers delivered by all, and included a high proportion of ECRs.
COT meeting and dinner
Britta Jensen as president of the CoT executive committee convened a meeting of tephrochronologists on Thursday 2 February at 6 pm. The new CoT Executive was introduced following the recent elections. Around 25 members of CoT enjoyed a special dinner at Wild Rice Thai Restaurant in “Eat Streat”, Rotorua, from 7.30 pm to around 10 pm on Thursday 2 February.
