Maar-diatremes - a course module

13 Jun 2016 | 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...

Confort 15 (Conflow improvement)

20 Jan 2015 | Contributor(s): Silvia Campagnola, Claudia Romano, Larry G Mastin, Alessandro Vona

We present an updated version of the Conflow model, an open-source numerical model for flow in eruptive conduits during steady-state pyroclastic eruptions (Mastin and Ghiorso, 2000). In the Confort 15 program, several updates were considered:The rheological parameters of the model are...

Brief Video Communications: Keweenaw Geoheritage

11 Apr 2016 | Contributor(s): William I Rose, Erika Vye

Erika Vye and I have fashioned outreach videos aimed at a broad public to educate about local geology in Michigan's Keweenaw Peninsula, where metal mining began thousands of years ago by First Nation immigrants who walked to America from Asia and found copper veins projecting from uncovered...

Tephra isopach, extent and volume calculation in R

04 Mar 2016 | Offline Tools | Contributor(s): Qingyuan Yang, Marcus I Bursik

The method presented here is used to interpolate the thickness distribution of tephra fall deposits from point measurements. It first reconstructs the general thickness decay pattern, or "trend," and then models the residuals that cannot be explained by the trend with...

FALL3D-7.1: A computational model for transport and deposition of tephra

10 Oct 2013 | Offline Tools | Contributor(s): Arnau Folch, Antonio Costa, Giovanni Macedonio

FALL3D (version 7.1) a 3-D time-dependent Eulerian model for the transport and deposition of tephra developed in the framework of a collaboration the Barcelona Supercomputing Center (BSC) and the Istituto Nazionale di Geofisica e Vulcanologia (INGV). The model solves a set of...

Lecture given during the short-course titled "Coping with volcanic unrest" held in Quito (Ecuador) on November 2014.The talks is aimed at illustrating the interaction and cooperation between scientists and dcision-makers, not only during Emergency phase. The focus of the presentation is...

Multidisciplinary constraints of hydrothermal explosions based on the 2013 Gengissig lake events, Kverkfjöll volcano, Iceland

29 Dec 2015 | Publications | Contributor(s): Cristian Montanaro

Hydrothermal explosions frequently occur in geothermal areas showing various mechanisms and energies of explosivity. Their deposits, though generally hardly recognised or badly preserved, provide important insights to quantify the dynamics and energy of these poorly understood explosive events....
