Natural Hazards Tephra Fallout Lab
04 Mar 2011 | Educational Materials | Contributor(s): Leah Michelle Courtland
This lab walks students through using the tephra2 education graphical user interface (gui) to investigate tephra fallout at Colima volcano. By the end of this lab, students should be able to:•understand that every volcanic event is different and so produces a unique deposit•convert from units of...

A new method to identify the vent location of tephra fall deposits based on thickness or maximum clast size measurements (SVL)
17 Apr 2018 | Offline Tools | Contributor(s): Qingyuan Yang, Marcus I Bursik, E Bruce Pitman
This tool presents a new method to identify the vent location of tephra fall deposits based on thickness or maximum clast size measurements. It is temporarily named "svl", which is short for Source Vent Locator. The method estimates the vent location by coupling semi-empirical models...

A fluid-dynamic model is developed to numerically simulate the non-equilibrium dynamics of polydisperse gas-particle mixtures forming volcanic plumes. Starting from the three-dimensional N-phase Eulerian transport equations for a mixture of gases and solid particles, we adopt an asymptotic...

INQUA–INTAV International Field Conference and Workshop: Crossing New Frontiers
14 Mar 2018 | Workshops | Contributor(s): Marcus I Bursik
The INQUA International Focus Group on Tephrochronology and Volcanism (INTAV) cordially invites you to participate in the Crossing New Frontiers - Tephra Hunt in Transylvania international field conference that aims to continue the long tradition of very successful inter-INQUA congress tephra...
Large Scale Experiments on Volcanic Processes (EOS)
19 Jul 2011 | Publications | Contributor(s): Greg A Valentine
Some of the least understood and most hazardous geologic processes involve complex multiphase flows, particularly those related to explosive volcanic eruptions. These phenomena inherently involve a wide range of characteristic length and time scales, as well as processes that are coupled across...
Maar-diatremes - a course module
13 Jun 2016 | Educational Materials | Contributor(s): Greg A Valentine, Alison Graettinger
Maar-diatremes are one of the most common volcanic landforms on Earth, and represent an end-member type of volcano whose eruptions are dominated by explosive, subsurface magma-water interaction. Thus they should form an important component of volcanology courses. The recent decade has...
Mono-Inyo Tephra Database
01 Aug 2017 | *Data Sets/Collections | Contributor(s): Marcus I Bursik
The Mono-Inyo Craters is a zone of active volcanism in California, USA, that extends from Mammoth Mountain and Long Valley caldera in the south to the islands of Mono Lake in the north. This resource provides the citation for the Mono-Inyo tephra database. The database can...
New Methods and Computer Codes for Volcanic Modelling
18 Jul 2013 | Workshops | Contributor(s): Martha Kane Savage, Yosuke Aoki, Thomas Lecocq, Jess Johnson, Florent Brenguier, Benoit Taisne, Charles Williams, Nico Fournier
This workshop was undertaken before the IAVCEI conference in July 2013, complementing the session on "Stress, strain and mass changes at active volcanoes. It brings together seismic and geodetic methods and computational approaches for modelling volcanic processes.Material presented includes:1....

Spread sheet to calculate tephra volume for exponential thinning
03 Dec 2014 | Offline Tools | Contributor(s): Manuel Nathenson, Judy Fierstein
An Excel spread sheet and instructions are provided to calculate tephra volume for exponential thinning on a log(thickness) versus square root of area plot. The spread sheet calculates volumes for a single straight line and for two straight lines. The equations for the calculations are from...
Tephra 2014 - Maximizing the potential of tephra for multidisciplinary science
09 Jan 2014 | Workshops | Contributor(s): Steven Kuehn, Solene Pouget, Marcus I Bursik
Tephra deposits are used by diverse communities: volcanologists, petrologists, tephrochronologists, paleoclimatologists, paleoecologists and archaeologists. To perhaps be too reductionist, volcanologists are generally interested in tephra to understand eruption behavior, frequency, and hazards;...
