  8. Pyroclastic density currents and local topography as seen with the conveyer model

    15 Apr 2014 | Publications | 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...

  9. Spread sheet to calculate tephra volume for exponential thinning

    03 Dec 2014 | Offline Tools | Contributor(s): Manuel Nathenson, Judy Fierstein

    An Excel spread sheet and instructions are provided to calculate tephra volume for exponential thinning on a log(thickness) versus square root of area plot. The spread sheet calculates volumes for a single straight line and for two straight lines. The equations for the calculations are from...

  11. Tephra 2014 - Maximizing the potential of tephra for multidisciplinary science

    09 Jan 2014 | Workshops | 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;...
