Commission on Tephrochronology

Flyer for a Geohorizon special issue call for papers, it reads: Tephra: from reconstructing past volcanic eruptions to modelling and forecasting future hazards Tephra produced during explosive volcanic eruptions can generate far-reaching social, economic, and environmental impacts with potentially devastating consequences for communities and livelihoods. By improving our understanding of how tephra is generated, transported and deposited - both during past events and ongoing activity - we can reduce these impacts and strengthen preparedness for future eruptions. This GeoHorizons volume will assemble a collection of papers that advance tephra studies, reflecting significant developments in the field over the past two decades. The volume will be organized into three sections: 1- Reconstructing past eruptions This opening section will highlight studies that use tephra to build eruption histories and reconstruct processes from historical and prehistoric explosive events. We welcome research involving field and deposit-based investigations, studies of sedimentary, archaeological and ice archives, modelling of past eruptions, and textural, geochemical and petrological analysis. 2- The generation, dispersion and sedimentation of tephra Focusing on recent or ongoing tephra-producing eruptions, this section invites studies examining trends in deposit characteristics such as grainsize and thickness, ash aggregation and particle settling processes, experimental work on plume dynamics and dispersion, and modelling of tephra generation transport and deposition. 3- Forecasting and mitigating the impacts of future explosive eruptions The final section looks to the future, with topics including tephra dispersion and impact modelling, climatic impacts and projections, volcanic hazard mapping, and applied studies that support risk reduction.

second page of flyer for special issue that says: This GeoHorizons volume will be of interest to physical volcanologists, geologists, tephrochronologists, hazard and climate modellers, and computational volcano and natural disaster scientists across academia, government and industry.

TA Shaun, from VARG, in his element teaching the students about volcanic ash, you can see two clear in this picture, Mazama at his knee and he is looking at Mount St Helens Yn

A group of young Bighorn sheep by Athabasca Glacier - a classic site in the Rockies!

Student Lachlan looks to the distance inspecting end moraines with the Athabasca glacier behind him.

Saskatchewan River Crossing with the loess cap on the terrace to the right, full of silt, paleosols and tephra!

Next we stop at a favourite: Saskatchewan Crossing. #strataday. Loess, paleosols, and three (!) volcanic ash: Mazama, Mount St Helens Yn and Bridge River. Doesn’t get much better, unless you like glaciers. We finish at Athabasca Glacier. Beautiful but heart breaking in her steady retreat. 🧪⚒️
