Abstract The Instituto Geofísico (IG-EPN) was created in 1983 by faculty of the Escuela
Politécnica Nacional, a public university in Quito, Ecuador, with the objective of assessing …

Volcanic debris flows (lahars) are highly destructive volcanic phenomena and present
significant challenges in numerical simulation. This manuscript tackles the three …

Sangay volcano is considered as one of the most active volcanoes worldwide. Nevertheless,
due to its remote location and low-impact eruptions, its eruptive history and hazard …

Stratovolcanoes are commonly characterised by cyclic eruptive activity marked by transitions
between dome-forming, Vulcanian, Subplinian and Plinian eruptions. Guagua Pichincha …

Tephra fallout hazard assessment is undertaken with probabilistic maps that rely on
numerical models. Regarding maps production, the input parameters of the model (including …

We present a scenario-based, probabilistic hazard assessment for the San Salvador
volcanic complex (SSVC), a volcanic field located in the vicinity of San Salvador that …

Structured expert judgment is crucial when dealing with significant epistemic and aleatoric
uncertainties, particularly in probabilistic hazard assessments, where decisions based on …

We describe a method for calculating the probability that a distal geographic location is
impacted by a pyroclastic density current (PDC) of a given size, considering the key related …

Sangay volcano (Ecuador) shows a quasi-continuous activity at least since the seventeenth
century and has produced several eruptions which affected towns and cities at considerable …

Proximal to the source, tephra fall can cause severe disruption, and populations of small
volcanically active islands can be particularly susceptible. Volcanic hazard assessments …
