..., this paper concentrates on lahar and flood risk assessment. Scenarios were derived with the help of the simulation codes LAHARZ and TITAN2D. The lahar risk assessment varies significantly depending on the method selected. LAHARZ simulations indicate that a considerable part of the urban areas...

... associated with eruptions. Volcanic debris flow hazard inundation maps have been produced using the Geographic Information System (GIS)-based modelling program, LAHARZ. The maps provide estimates of the areas that would be inundated by future moderate to large-magnitude events. Given the available data...

... the LAHARZ model, based on empirical relationships. Several volumes were considered because of the range of potential lahar-initiating events, such as ice melting or mobilization of loose pyroclasts. Simulations indicate that valleys located west of the volcano are likely to be inundated by lahars, even...

... methods include those correlations based on the area-volume relationship of a large landslide (e.g. H ungr , 2002 ); a probabilistic approach to estimate runout based on area-volume relationship was carried out by I verson et alii (1998) with the LAHARZ model. A comprehensive overview...

... the simulation models LAHARZ and TITAN2D to model lahars and floods as the most probable hazard scenario for the town of Arequipa, close to El Misti volcano. Sheridan et al. (this volume) consider the uncertainty of geological and volcanological data for the calibration of simulation models. The simulation code...

... the hazard posed by lahars generated in the caldera lakes of Fogo and Furnas. The LAHARZ model is used, a code written in the ARCINFO Macro Language and developed by the US Geological Survey ( Schilling 1998 ). The program uses the results of scaling and statistical analyses of the geometry of several lahars...

The TITAN2D model is an improvement over other geophysical flow models such as Laharz ( Iverson et al., 1998 ) and Flow3D ( McEwen and Malin, 1989 ; Kover, 1995 ) in that it is based on an incompressible Coulomb continuum model rather than a much-simplified “sliding-block” model or “valley...

..., such as LAHARZ or PYROFLOW, have shown success ( Wadge et al. 1998 ; Wadge 2009 ; Widiwijayanti et al. 2008 ) at both simulating the expected inundation from dense basal avalanches and, to a first order, delineating the probable ash-cloud surge extent. These models have the advantage of being...
