Abstract

Using a translation of the code of Eject! (Mastin 2001; 2011) in Matlab (Strehlow et al., 2019), we provide a workflow for probabilistic analyses of ballistic ejections during volcanic eruptions that can be used for hazard assessments. An example for the use of this workflow and a detailed description of the method can be found in Strehlow et al. (2017).

Ackowledgements:

We would like to acknowledge Larry Mastin for providing his original code for Eject! and his assistance with the translation into Matlab.
