Journal ArticleDOI
Total grain-size distribution and volume of tephra-fall deposits
TL;DR: The authors used the Voronoi Tessellation method to estimate the total grain-size distribution and volume of tephra-fall deposits from the Ruapehu volcano in New Zealand.
Journal ArticleDOI
Thickness variations and volume estimates of tephra fall deposits: the importance of particle Reynolds number
TL;DR: In this article, it was shown that major changes in thinning rate occur as the particle size decreases with distance from the vent, as a consequence of the change of settling behavior from high to low Reynolds number as predicted by W.I. Rose.
Journal ArticleDOI

TL;DR: In 1997, the Soufriere Hills Volcano on Montserrat produced 88 Vulcanian explosions, with an initial high-intensity phase lasting a few tens of seconds and a lower-intensity, waning phase lasting 1 to 3 hours as mentioned in this paper.
Journal ArticleDOI
Probabilistic modeling of tephra dispersal: Hazard assessment of a multiphase rhyolitic eruption at Tarawera, New Zealand
Costanza Bonadonna,Costanza Bonadonna,Charles B. Connor,Bruce F. Houghton,Laura Connor,Marc A. Byrne,Arlene Laing,Thea K Hincks +7 more
TL;DR: In this article, an advection-diffusion model (TEPHRA) was developed to assess the tephra fall hazard from a future rhyolitic eruption at Tarawera of a similar scale.
Journal ArticleDOI
A review of volcanic ash aggregation
TL;DR: In this paper, the authors used remote sensing studies of volcanic ash clouds with field measurement and sampling, and lab experiments are required to fill current gaps in knowledge surrounding the theory of ash aggregate formation.
