Pyroclastic density currents and local topography as seen with the conveyer model
15 Apr 2014 | Contributor(s): Domenico M. Doronzo
Pyroclastic density currents (PDCs) are multiphase flows generated during explosive volcanic eruptions, and they move down the volcano, and over the surrounding topography. The flow-topography interaction can play a fundamental role in the sedimentary processes, and in the resulting deposit...

Tephra 2014 - Maximizing the potential of tephra for multidisciplinary science
09 Jan 2014 | Contributor(s): Steven Kuehn, Solene Pouget, Marcus I Bursik
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;...

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...
