How rainfall influences tephra fall loading — an experimental approach [PDF]
Bulletin of Volcanology, 2021 AbstractThe load a tephra fall deposit applies to an underlying surface is a key factor controlling its potential to damage a wide range of assets including buildings, trees, crops and powerlines. Though it has long been recognised that loading can increase when deposits absorb rainfall, few efforts have been made to quantify likely load increases ...

Drivers of crop impacts from tephra fallout
Volcanica, 2022 Agriculture is an economic and social pillar for the least developed countries. When these regions host volcanoes that exhibit explosive behaviour, a serious risk for agricultural production arises as crops endure various impacts from tephra fall.

Laboratory tests to understand tephra sliding behaviour on roofs
Journal of Applied Volcanology, 2023 Following explosive eruptions, loading from tephra fall deposits can lead to roof collapse. However, the load may be reduced significantly by tephra sliding on pitched roofs. We present small-scale laboratory tests to investigate tephra sliding behaviour

Environmental Impact of Silicic Magmatism in Large Igneous Province Events
Geophysical Monograph Series, Page 133-151., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Real-Time Tephra Detection and Dispersal Forecasting by a Ground-Based Weather Radar
Remote Sensing, 2021 Tephra plumes can cause a significant hazard for surrounding towns, infrastructure, and air traffic. The current work presents the use of a small and compact X-band multi-parameter (X-MP) radar for the remote tephra detection and tracking of two eruptive

Quantifying uncertainties in the measurement of tephra fall thickness [PDF]
Journal of Applied Volcanology, 2013 The uncertainties associated with tephra thickness measurements are calculated and implications for volume estimates are presented. Statistical methods are used to analyse the large dataset of Walker and Croasdale J Geol Soc 127:17-55, 1971 of the Fogo A plinian deposit, Sao Miguel, Azores.

Reconstructing tephra fall deposits via ensemble-based data assimilation techniques [PDF]
Geoscientific Model Development, 2023 In recent years, there has been a growing interest in ensemble approaches for modelling the atmospheric transport of volcanic aerosol, ash, and lapilli (tephra).
