Residential building and occupant vulnerability to tephra fall [PDF]
Natural Hazards and Earth System Sciences, 2005 Plinian and subplinian volcanic eruptions can be accompanied by tephra falls which may last hours or days, posing threats to people, buildings and economic activity. Numerous historical examples exist of tephra damage and tephra casualties.

Revised Minoan eruption volume as benchmark for large volcanic eruptions [PDF]
Nature Communications, 2023 Despite their global societal importance, the volumes of large-scale volcanic eruptions remain poorly constrained. Here, we integrate seismic reflection and P-wave tomography datasets with computed tomography-derived sedimentological analyses to estimate

Vegetation responses to past volcanic disturbances at the Araucaria araucana forest‐steppe ecotone in northern Patagonia [PDF]
Ecology and Evolution, 2022 Volcanic eruptions play an important role in vegetation dynamics and its historical range of variability. However, large events are infrequent and eruptions with a significant imprint in today's vegetation occurred far in the past, limiting our ...

Tephra fall impacts to buildings: the 2017–2018 Manaro Voui eruption, Vanuatu
Frontiers in Earth ScienceBuilding damage from tephra falls can have a substantial impact on exposed communities around erupting volcanoes. There are limited empirical studies of tephra fall impacts on buildings, with none on tephra falls impacting traditional thatched timber ...

Morphology and formation of glassy volcanic ash from the August 12-15, 1991 eruption of Hudson Volcano, Chile [PDF]
Latin American Journal of Sedimentology and Basin Analysis, 2005 The 1991 explosive eruption of Hudson volcano in Chile ejected about 2.7 km³ (DRE) of basalt and trachyandesite magma as tephra fall. A majority of the fallout occurred from an eruption during the period August 12-15, 1991, producing an extensive deposit
