Natural Hazards Tephra Fallout Lab
04 Mar 2011 | Educational Materials
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
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...

La erupción del volcán Calbuco en 2015: Volcanología, sociedad y ecosistemas
25 Apr 2017 | Publications
La erupción del 22-23 de abril de 2015 del Volcán Calbuco tuvo impactos en las actividades sociales y ecosistemas en el sur de Chile y en Argentina, debido a la espesa caída de piroclastos, corrientes calientes de gases y rocas, además de flujos de lodo...
Large Scale Experiments on Volcanic Processes (EOS)
19 Jul 2011 | Publications
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...
Los depósitos de caída de tefra: Una breve revisión sobre su cuantificación y análisis para la clasificación de erupciones volcánicas explosivas, con ejemplos Latinoamericanos
15 Nov 2015 | Publications
La cuantificación de los depósitos volcánicos es una de las herramientas más utilizadas en la actualidad para clasificar la magnitud de la actividad volcánica y determinar los peligros volcánicos asociados. En el caso especial de las erupciones...
Maar-diatremes - a course module
27 Nov 2021 | Educational Materials
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
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...

Spread sheet to calculate tephra volume for exponential thinning
27 Nov 2021 | Offline Tools
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
27 Nov 2021 | Workshops
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;...

Tephra inversion with Tephra2 and the Metropolis-Hastings algorithm
27 Nov 2021 | Offline Tools
We couple the Metropolis-Hastings algorithm (Hastings, 1970) with the volcanic ash transport model Tephra2 (Bonadonna et al, 2005; 2010), and present the coupled algorithm as a new method to estimate the Eruption Source Parameters (ESPs) of volcanic eruptions based on mass per unit area...
