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...

1st IAVCEI/GVM Workshop: "From Volcanic Hazard to Risk Assessment", Geneva, 27-29 June 2018

18 Dec 2018 | Workshops

The complexity of volcanic risk analysis typically resides in the interaction of multiple hazard, vulnerability and exposure aspects dynamically acting over various spatial and temporal scales. Risk analyses provide an evidence-based approach to development and implementation of proactive...

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...

Maar-diatremes - a course module

04 Mar 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...
