This review describes the mechanisms of lahars and debris flows, and their impacts on
buildings, infrastructure and other valuables. Lahars are a type of debris flow restricted to …

This article provides background information about Ecuador's general volcanic setting, as an
introduction to the numerous articles in this Special Issue of the Journal dealing with the …

Several issues relevant to the mobility of long-runout landslides are examined. A central
idea developed in this paper is that the apparent coefficient of friction (ratio of the fall height …

The Andean volcanic arc includes over 200 potentially active Quaternary volcanoes, and at
least 12 giant caldera/ignimbrite systems, occurring in four separate segments referred to as …

Worst-case or high-end subduction-related earthquakes and tsunamis of 2004 and 2011 are
painfully fresh in our memories. High-end subduction-related volcanic eruptions have not …

An effective assessment of shallow landslide hazard requires spatially distributed modelling
of triggering processes. This is possible by using physically based models that allow us to …

Pyroclastic soils mantling a wide area of the Campanian Apennines are subjected to
recurrent instability phenomena. This study analyses the 5 and 6 May 1998 event which …

Landslides from massive rock slope failure (MRSF) are a major geological hazard in many
parts of the world. Hazard assessment is made difficult by a variety of complex initial failure …

Abstract At Cotopaxi volcano, Ecuador, rhyolitic and andesitic bimodal magmatism has
occurred periodically during the past 0.5 Ma. The sequential eruption of rhyolitic (70–75 …

Lahars are rapid flows of mud–rock slurries that can occur without warning and
catastrophically impact areas more than 100 km downstream of source volcanoes …
