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...

14 Aug 2015 | Offline Tools | Contributor(s): Matteo Cerminara, Tomaso Esposti Ongaro
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...

Direct sampling of volcanic clouds
08 Feb 2011 | Presentations | Contributor(s): William I Rose
Volcanic clouds have only sporadically been directly sampled. Sampling is advantageous to validate remote sensing. Direct sampling was more common in the 1978-1984 period before the hazards to jet aircraft were understood and when piston aircraft sampling was more prevalent. This sampling...
