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.

Tephra fall clean-up in urban environments [PDF]

Journal of Volcanology and Geothermal Research, 2015
Abstract Tephra falls impact urban communities by disrupting transport systems, contaminating and damaging buildings and infrastructures, and are potentially hazardous to human health. Therefore, prompt and effective tephra clean-up measures are an essential component of an urban community's response to tephra fall. This paper reviews case studies of

Automating tephra fall building damage assessment using deep learning [PDF]

Natural Hazards and Earth System Sciences
In the wake of a volcanic eruption, the rapid assessment of building damage is paramount for effective response and recovery planning. Uncrewed aerial vehicles, UAVs, offer a unique opportunity for assessing damage after a volcanic eruption, with the ...

Disruption of tephra fall deposits caused by lava flows during basaltic eruptions [PDF]

Bulletin of Volcanology, 2015
Observations in the USA, Iceland and Tenerife, Canary Islands reveal how processes occurring during basaltic eruptions can result in complex physical and stratigraphic relationships between lava and proximal tephra fall deposits around vents. Observations illustrate how basaltic lavas can disrupt, dissect (spatially and temporally) and alter sheet-form

Tephra fall at Tungurahua Volcano (Ecuador) – 1999-2014: An Example of Tephra Accumulation from a Long-lasting Eruptive Cycle

Geofísica Internacional, 2015
El volcán Tungurahua despertó en 1999 después de 75 años de quietud, y su actividad continua hasta el presente (2015). Luego de quince años de erupciones, casi 0.13 km³ de tefra han sido emitidos y depositados principalmente hacia el oeste y suroeste del

Uncertainty Quantification of Eruption Source Parameters Estimated From Tephra Fall Deposits

Geophysical Research Letters, 2022
AbstractUncertainty quantification (UQ) in eruption source parameters, like tephra volume, plume height, and umbrella cloud radius, is a challenge for volcano scientists because tephra deposits are often sparsely sampled due to burial, erosion, and related factors.

Determining tephra fall deposit thickness in sedimentary record from magnetic susceptibility curve: Example of four Ethiopian tephras

Geochemistry, Geophysics, Geosystems, 2004
The ejecta volume associated to a volcanic eruption is commonly estimated by extrapolating the exponential thinning relations beyond the tephra fall deposit thickness preserved in the sedimentary record. The thickness of a tephra is usually determined visually, eventually including the counting of the volcanic grains to take into account the vertical ...

Tephra fall impacts to buildings: the 2017–2018 Manaro Voui eruption, Vanuatu

Frontiers in Earth Science
Building 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 ...

Creating a digital database of tephra fallout distribution and frequency in Japan

Journal of Applied Volcanology, 2022
Tephra fallout is a potential hazard to livelihoods, critical infrastructure, and health, even in areas that are far from volcanoes. Therefore, it is important to quantitatively evaluate tephra fall hazards for both residents and infrastructure around ...
