Updated version of an algorithm for tephra isopach, extent and volume calculation in R
18 Oct 2016 | Contributor(s):: Marcus I Bursik, Qingyuan Yang
We have updated an algorithm that aids in isopach construction, and volume and extent calculation of tephra fall deposits. The program is written in R. Documentation has been improved, and we now include example datasets for the North Mono eruption and Fogo A. The algorith and...

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...
