Special volume in the Journal of Volcanology and Geothermal Research
The Commission supported a special volume in the Journal of Volcanology and Geothermal Research presenting results of the eruption column model inter-comparison study. View the special issue here. The accurate description of the dynamics of convective plumes developed during explosive volcanic eruptions represents...

About THM IAVCEI Commission
The IAVCEI Commission on Tephra Hazard Modelling (THM) was born in 2003 to improve our quantitative understanding of tephra hazards using numerical models and field data. Over the past 20 years, the commission has actively organized workshops, symposia, and fostered communication among numerical modelers, field geologists, and operational forecasters from the VAACs and observatories. A few of the notable outcomes include: a dataset for the validation of Volcanic Tephra Sedimentation models, scientific recommendations for collecting the largests clasts of tephra deposits for the determination of plume height, a consensual document from two IUGG-WMO workshops on volcanic ash and aviation (2010, 2013), and a JVGR special issue on eruption column model inter-comparison.
