Confort 15 (Conflow improvement)

22 Apr 2016 | 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...

An assessment of hydrothermal alteration in the Santiaguito lava dome complex, Guatemala: implications for dome collapse hazards

28 Feb 2013 | Contributor(s): Jessica L. Ball, Eliza S Calder, Marc Bernstein

A combination of field mapping, geochemistry, and remote sensing methods has been employed to determine the extent of hydrothermal alteration and assess the potential for failure at the Santiaguito lava dome complex, Guatemala. The 90-year-old complex of four lava domes has only experienced...

Volcanic clouds observed by the A-Train satellite constellation

12 Mar 2012 | Contributor(s): Simon Carn

A collection of images showing volcanic eruption clouds detected by NASA's A-Train satellite constellation, which includes the Aqua, CALIPSO, CloudSat and Aura satellites. These examples demonstrate the unique ability of the A-Train to provide coincident, multi-spectral, active and passive remote...

Large Scale Experiments on Volcanic Processes (EOS)

19 Jul 2011 | 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...
