1-1-1-1-1-1-1-1-1-1-1-1-1-1 From: Thomas Aubry <thom.aubry@xxxxxxxxx> Dear colleagues, We are excited to announce our next Ashvances in Tephra seminar, organised by the IAVCEI Commission for Tephra Hazard Modelling. The time for this seminar will be 15.30 UTC on February 24 2025. Please register using this link <https://urldefense.com/v3/__https://events.teams.microsoft.com/event/2ac3620f-77be-4fa4-ba9a-e43e9d97711a@912a5d77-fb98-4eee-af32-1334d8f04a53__;!!IKRxdwAv5BmarQ!a5w2uEzjgimjz_qEb-ACWvb29zOUMYydu4XUYG0p9MppHmYSNffOYZjUm9L07BdYJblnbzdTUIGL95v82Ta0nJUw0w$> and use this time zone converter <https://urldefense.com/v3/__https://www.timeanddate.com/worldclock/converter.html?iso=20250224T153000&p1=136__;!!IKRxdwAv5BmarQ!a5w2uEzjgimjz_qEb-ACWvb29zOUMYydu4XUYG0p9MppHmYSNffOYZjUm9L07BdYJblnbzdTUIGL95v82TZnlEIVgQ$> to check the time of the event in your time zone. It is our pleasure to welcome *Dr Silvia Massaro* (University of Bari and INGV Bologna, Italy) and *Dr Edwin Telenchana* (Instituto GeofÃsico of the Escuela Politécnica Nacional, Ecuador) as our speakers. They will be presenting: - Silvia Massaro: *On the long-term multi-source probabilistic hazard assessment posed by tephra fallout: an example from Neapolitan volcanoes* - Edwin Telenchana: *Record of eruptions occurred in the northern Andes during the Holocene: New results obtained from the Potrerillos peatbog, Chiles-Cerro Negro Volcanic Complex* We recognise that the time of this event will not be amenable to everyone. We aim to rotate our seminars around different time zones as much as possible to reach audience members from across the globe and give everyone an equal and fair chance to participate in the seminars. We are always looking out for new speakers in future seminars. We aim to hold a seminar every quarter (c. 3 months), with each seminar lasting for about an hour. Two speakers will be allocated 15-20-minute talks with 5-10 minutes for questions. The last 10 minutes will be kept for general discussions, e.g., how the Tephra Hazard Modelling Commission can serve you better, and socializing/networking. At least one of the talks will be by an early-career researcher, and we will use this seminar series to showcase the work of researchers with backgrounds underrepresented in volcanology. Time zones will be selected based on the location(s) of speakers and we will aim to rotate these as much as possible to reach audience members from across the globe and give everyone an equal and fair chance to participate in the seminars. We aim that by having two talks per seminar, each session will cover multiple topics, including but not limited to numerical modelling, field studies, laboratory experiments and risk communication/management. *Please use this form * *https://forms.gle/z7LB3TJDWauD3qCs6* <https://urldefense.com/v3/__https://forms.gle/z7LB3TJDWauD3qCs6__;!!IKRxdwAv5BmarQ!ZYbhk9h-Mu55gmuoIMwvyIC8M7kzQzsnRi4gp6yn6R6g390Oz7FTA4cXbI5RMdelaV_WHtdXISDx-y_Zhg$>* to register your interest in being a speaker or suggest a student/colleague*. We particularly encourage (self-) nomination of diverse and early career scientists. We look forward to welcoming you to what promises to be a fantastic seminar. *Please don't forget that you can sign up to our commission and mailing list anytime at **this link* <https://urldefense.com/v3/__https://www.jiscmail.ac.uk/cgi-bin/webadmin?SUBED1=IAVCEITHM&A=1__;!!IKRxdwAv5BmarQ!a5w2uEzjgimjz_qEb-ACWvb29zOUMYydu4XUYG0p9MppHmYSNffOYZjUm9L07BdYJblnbzdTUIGL95v82TZiAkAZqQ$> *.* All the best, Alastair, Paul and Thomas Co-chairs of IAVCEIâ??s Tephra Hazard Modelling Commission 1-1-1-1-1-1-1-1-1-1-1-1-1-1 ------------------------------
