Despite major advancements in knowledge on disaster risks and disasters caused by
natural hazards, the number and severity of disasters are increasing. Convolving natural …

The behaviour of dry and wet volcanic granular flows is one of the main research topics in
present day geophysics and volcanology. It involves various disciplines (eg sedimentology …

High concentration pyroclastic density currents (PDCs) are hot avalanches of volcanic rock
and gas and are among the most destructive volcanic hazards due to their speed and …

Abstract Analysis of the pre-and post-eruption topography, together with observations of the
avalanche deposition sequence, yields a triggering mechanism for the 6 August 2012 …

The emplacement of lava flows is mainly controlled by the topography, which is an essential
input parameter to all numerical simulation models. The sensitivity of these models to the …

Topography is a fundamental factor influencing the emplacement of lava flows. We assess
the impact of topographic resolution on the thermorheological PyFLOWGO model …

This paper presents the results of lahar modelling in the town of Villa La Angostura
(Neuquén-Argentina) based on the Two-Phase-Titan modelling computer code. The …

Pyroclastic density currents (PDCs) are hot flowing mixtures of gas and pyroclasts that can
cause widespread loss of life and structural damage around the erupting volcano. Hazard …

Detailed topographic data from volcanoes can yield key insights into the controls on volcanic
activity as well as hazards. High‐resolution digital elevation models generated from remote …

Understanding past eruption dynamics at a volcano is crucial for forecasting the range of
possible future eruptions and their associated hazards and risk. In this work we use …
