Tephra fallout hazard maps with uncertainty quantification for Cotopaxi and Guagua Pichincha volcanoes

Abstract:

Uncertainty quantification of the model – definition of mean under/overestimation coefficientes of the model Uncertainty quantification for the probability of occurrence of different eruption types for the range of eruptive source parameters – expert elicitation session Hazard maps produced for sub-plinian and plinian eruptions considered separately and together Cotopaxi (4 eruption types) Guagua Pichincha (2 eruption types) Two map types: for a given tephra accumulation threshold and different probabilities for a given probabilité donnée et différents seuils d'accumulation de téphra Three maps (« lower », « natural » et « upper ») that quantify the different sources of uncertainty Quito : hazard curves defined for 10 sensitive sites
