Tephra fall can lead to significant additional loading on roofs. Understanding the relevant geomechanical properties of tephra is critical when assessing the vulnerability of buildings to tephra fall and designing buildings to withstand tephra loads ...

Environmental Impact of Silicic Magmatism in Large Igneous Province Events
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
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

Remotely assessing tephra fall building damage and vulnerability: Kelud Volcano, Indonesia [PDF]
AbstractTephra from large explosive eruptions can cause damage to buildings over wide geographical areas, creating a variety of issues for post-eruption recovery. This means that evaluating the extent and nature of likely building damage from future eruptions is an important aspect of volcanic risk assessment.

Estimating tephra fall volume from point-referenced thickness measurements
SUMMARYWe describe an algorithm for producing an approximate 95 per cent confidence interval (CI) for the bulk volume of tephra fall deposits, based on point-referenced tephra thickness measurements, and expert judgement. Applied to the Aso-4 eruption, our algorithm gives a 95 per cent CI of $[220\, \mathrm{km^3}, 370\, \mathrm{km^3}]$.

Hiroshi Machida −respected tephrochronologist, teacher, leader [PDF]
Professor Emeritus Hiroshi Machida (Hiroshi hereafter) is the leading tephrochronologist of his generation in Japan. Perhaps more than any other geoscientist from Japan, Hiroshi carried the insights and advances of tephra studies and their application in

Quantifying uncertainties in the measurement of tephra fall thickness [PDF]
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.

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 ...

We use the tephrostratigraphic framework along the Aegean Volcanic Arc established in Part 1 of this contribution to determine hemipelagic sedimentation rates, calculate new tephra ages, and constrain the minimum magnitudes of (sub)plinian eruptions of ...

Vegetational response to tephra deposition and land-use change in Iceland: a modern analogue and multiple working hypothesis approach to tephropalynology [PDF]
Evidence is provided from the joint application of tephrochronology and palynology in two Icelandic locations — the island of Papey off the east coast and Seljaland in the south.
