Probability map of PDC by using a modifed approach of the energy cone model and topographic information derived from the SRTM 30 m elevation model.
1st IAVCEI/GVM Workshop: "From Volcanic Hazard to Risk Assessment", Geneva, 27-29 June 2018
18 Dec 2018
The complexity of volcanic risk analysis typically resides in the interaction of multiple hazard, vulnerability and exposure aspects dynamically acting over various spatial and temporal scales. Risk analyses provide an evidence-based approach to development and implementation of proactive...

1D-steady state model for volcanic conduits
PYFLOW_2.0. A new tool for estimating the impact parameters and the deposition rate and time of dilute PDCs based on field data
22 Nov 2017 | Contributor(s): Marcus I Bursik
PYFLOW_2.0 is a hazard tool for the calculation of the impact parameters of dilute pyroclastic density currents (DPDCs). DPDCs represent the dilute turbulent type of gravity flows that occur during explosive volcanic eruptions; their hazard is the result of their mobility and the capability...

Confort 15 (Conflow improvement)
22 Apr 2016 | Contributor(s): Marcus I Bursik
We present an updated version of the Conflow model, an open-source numerical model for flow in eruptive conduits during steady-state pyroclastic eruptions (Mastin and Ghiorso, 2000). In the Confort 15 program, several updates were considered:The rheological parameters of the model are...
An assessment of hydrothermal alteration in the Santiaguito lava dome complex, Guatemala: implications for dome collapse hazards
28 Feb 2013
A combination of field mapping, geochemistry, and remote sensing methods has been employed to determine the extent of hydrothermal alteration and assess the potential for failure at the Santiaguito lava dome complex, Guatemala. The 90-year-old complex of four lava domes has only experienced...
Volcanic clouds observed by the A-Train satellite constellation
12 Mar 2012
A collection of images showing volcanic eruption clouds detected by NASA's A-Train satellite constellation, which includes the Aqua, CALIPSO, CloudSat and Aura satellites. These examples demonstrate the unique ability of the A-Train to provide coincident, multi-spectral, active and passive remote...
