  1. Maar-diatremes - a course module

    0.0 out of 5 stars 

    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...

  2. Tephra isopach, extent and volume calculation in R

    NOTE The code is now maintained on GitHub: https://github.com/e5k/TOTGS Follow updates on: https://e5k.github.io/  Quantifying the total grainsize distribution (TGSD) is a necessary step to achieve a thorough characterization of a given tephra deposit. Several methods exist to...

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

    0.0 out of 5 stars 

    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;...
