Probabilistic studies with Eject! for Matlab
25 Jun 2019 | Contributor(s): Karen Strehlow, Laura Sandri, Jo Gottsmann, Geoff Kilgour, Alison Rust, Roberto Tonini
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...

Eject! for Matlab
24 Jun 2019 | Contributor(s): Karen Strehlow, Laura Sandri, Jo Gottsmann, Geoff Kilgour, Alison Rust, Roberto Tonini
The program "Eject!" calculates the trajectories of ballistic projectiles from volcanic eruptions (Mastin, 2001; 2011). The code was originally written in Visual Basic, which we have now translated into an editable Matlab procedure (Strehlow et al., 2017). Input parameters...

Towards a probabilistic scheme: How can we recognize and track non-magmatic unrest and related hazards?
18 Feb 2014 | Publications | Contributor(s): dmitri rouwet, Laura Sandri, Warner Marzocchi, Jo Gottsmann
Eruption forecasting is a major goal in volcanology. The intrinsic complexity and non-linearity of volcanic systems has recently led to an intertwining of deterministic to probabilistic eruption forecasting methods. However, many volcanoes often pass states of non-eruptive and non-magmatic unrest...

A probabilistic framework to quantify hazard related to volcanic lakes
23 Aug 2013 | Presentations | Contributor(s): dmitri rouwet, Laura Sandri, raul mora-amador
The presence of a volcanic lake increases the probability of certain types of volcanic hazard. So far, this topic has only been approached in a purely deterministic way, e.g.: phreatic-phreatomagmatic eruption behavior, dynamics of Nyos-type gas bursts and gas accumulation and dispersion, models...

BET_EF application during the Colima Exercise in Nov. 2012
26 Apr 2013 | Miscellaneous | Contributor(s): Laura Sandri, dmitri rouwet
This short document describes all the settings for BET EF for Colima volcano that were decided BEFORE the beginning of the Colima exercise. The settings were decided by Laura Sandri and Dmitri Rouwet, stemming from 2 reports that we had received from Raul Arambula and Gabriel Reyes of UNAM. The...

Bayesian Event Tree for Volcanic Hazards - BET_VH theory
13 Nov 2012 | Presentations | Contributor(s): Jose L. Palma, Laura Sandri
This is a presentation given by Laura Sandri at the University of Buffalo, US, in May 2011. In this presentation Laura explains the theory behind the BET_VH computer code, which is available as an online tool here on Vhub.
