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...

Tephra isopach, extent and volume calculation in R

04 Mar 2016 | 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...

Spread sheet to calculate tephra volume for exponential thinning

10 Apr 2015 | 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...

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...

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;...
