Eruption! A Volcanic Crisis Simulation

13 Mar 2011 | Educational Materials | Contributor(s): Marcus I Bursik

www.dartmouth.edu/~renshaw/eruption/ Eruption! is a web-based simulation of a twenty-five day period of volcanic activity leading up to a volcanic crisis, a situation in which lives are endangered. The immediate goal of the simulation is to highlight the hazards associated with volcanic eruptions...

Estimating Volcanic Risk in the Lesser Antilles

26 Sep 2013 | Publications | Contributor(s): Michal Camejo, Richard E.A. Robertson

The potential catastrophic effects of future volcanic eruptions in the Lesser Antilles can be decreased by the utilisation of effective risk quantification measures and their subsequent incorporation into disaster risk reduction strategies. A volcanic risk study conducted by the Norwegian...

Estimation and propagation of volcanic source parameter uncertainty in an ash transport and dispersal model: application to the Eyjafjallajokull plume of 14--16 April 2010

19 Sep 2012 | Publications | Contributor(s): Marcus I Bursik

Data on source conditions for the 14 April 2010 paroxysmal phase ofthe \eyja~ eruption, Iceland, have been used as inputs to atrajectory-based eruption column model, . This model has inturn been adapted to generate output suitable as input to the volcanicash transport and dispersal model, , which...
