“…Although not known in detail, trigger mechanisms such as saturation of sediment due to melting of snow and ice have been suggested, reinforced by partly impermeable ground layers due to permafrost or ice-core occurrence, and the formation and release of subglacial water reservoirs Oropeza Villalobos, 2001;Palacios et al, 2001). The July 1, 1997, lahar was non-cohesive and transformed into a hyperconcentrated streamflow further downstream (Capra et al, 2004). The sediment volume was estimated between 330,000 and 400,000 m 3 with a sediment content of about 25% (Sheridan et al, 2001;Capra et al, 2004).…”

“…The most remarkable ones took place in 1995, 1997 and 2001 along the Huiloac gorge and its tributaries, extending downstream to the town of Santiago Xalizintla (Sheridan et al, 2001;Capra et al, 2004). These lahars all occurred in connection with eruptive activity and related melting of Ventorillo glacier (González Huesca and Delgado Granados, 1997).…”

“…The glaciers of Popocatépetl experienced a strong retreat in recent years, accelerated by the eruptive activity (Delgado Granados, 1997;Huggel and Delgado, 2000;Julio Miranda and Delgado Granados, 2003). A number of lahar events since volcanic activity resumed at Popocatépetl in 1994 were directly related to snow and ice melting of glaciers, and several lahars reached populated areas Palacios et al, 2001;Bursik et al, 2003;Capra et al, 2004;Julio Miranda et al, 2005). The information available for such events enables realistic analysis of the modeled lahars.…”

Lahars are among the most serious and far-reaching volcanic hazards. In regions with potential interactions of lahars with populated areas and human structures the assessment of the related hazards is crucial for undertaking appropriate mitigating actions and reduce the associated risks. Modeling of lahars has become an important tool in such assessments, in particular where the geologic record of past events is insufficient. Mass-flow modeling strongly relies on digital terrain data. Availability of digital elevation models (DEMs), however, is often limited and thus an obstacle to lahar modeling. Remote-sensing technology has now opened new perspectives in generating DEMs. In this study, we evaluate the feasibility of DEMs derived from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) and the Shuttle Radar Topography Mission (SRTM) for lahar modeling on Popocatépetl Volcano, Mexico. Two GIS-based models are used for lahar modeling, LAHARZ and a flow-routing-based debris-flow model (modified single-flow direction model, MSF), both predicting areas potentially affected by lahars. Results of the lahar modeling show that both the ASTER and SRTM DEMs are basically suitable for use with LAHARZ and MSF. Flow-path prediction is found to be more reliable with SRTM data, though with a coarser spatial resolution. Errors of the ASTER DEM affecting the prediction of flow paths due to the sensor geometry are associated with deeply incised gorges with north-facing slopes. LAHARZ is more sensitive to errors of the ASTER DEM than the MSF model. Lahar modeling with the ASTER DEM results in a more finely spaced predicted inundation area but does not add any significant information in comparison with the SRTM DEM. Lahars at Popocatépetl are modeled with volumes of 1 × 10 5 to 8 × 10 6 m 3 based on ice-melt scenarios of the glaciers on top of the volcano and data on recent and historical lahar events. As regards recently observed lahars, the travel distance of lahars of corresponding volume modeled with LAHARZ falls short by 2 to 4 km. An important finding is that the travel distance of potential lahar events modeled with LAHARZ may differ by about 2 km when using SRTM or ASTER data because of varying lateral flow-volume distribution. As a consequence, verification and sensitivity analysis of the DEM is fundamental to deriving hazard maps from predicted modeled inundation areas. Because of the global coverage of this type of remote-sensing data, the conclusion that both SRTM and ASTER-derived DEMs are feasible for lahar modeling opens a wide field of application in volcanic-hazards studies.

“…Igualmente sucedió en la zona arqueológica de Cholula, Cacaxtla y Xochitécatl (México) donde se encontró evidencia de un lahar proveniente del volcán Popocatépetl, similar al anterior ocurrido hace 1100 años (Macías, 2005). Sobre la Faja Volcánica Transmexicana (FVTM) y entre los límites territoriales de los estados de Morelos, Puebla y Ciudad de México se encuentra el volcán Popocatépetl (Capra et al, 2004), catalogado como uno de los más peligrosos a nivel mundial por los más de 25 millones de personas que habitan en un radio aproximado de 100 km del cráter (Espinasa, 2014). Se clasifica como un estratovolcán (Aguilera y Ordóñez, 1895; Delgado-Granados y Brugman, 1994) con una actividad intermitente.…”

“…Es de notar que la barranca Huiloac atraviesa la localidad, lo cual facilita que los lahares lleguen a la población. Por ejemplo, en marzo de 1997 un flujo de lodo llegó a Santiago Xalitzintla, afectando una casa e inundando lotes con árboles frutales (Sheridan et al, 2001;Capra et al, 2004;Julio et al, 2005). Volcanes como el Vesubio y Campi Flegrei en Italia, Popocatépetl en México, Sakurajima en Japón y Nevado del Ruiz en Colombia, son escenarios de estudio por la formación de importantes flujos de gravedad; de este modo, los lahares se convierten en una amenaza latente para poblaciones que se encuentran alrededor de volcanes (Valentine,…”
