CUADRO DE UBICACIÓN NOTA IMPORTANTE Este documento forma parte de una serie especial de mapas de peligro volcánico cuya finalidad es proveer información sintética de carácter orientativo para su uso en situaciones de crisis. La zonificación presentada es el resultado integrado de un análisis cuantitativo que considera múltiples escenarios erupti- vos escogidos de acuerdo a los antecedentes geológicos de este centro volcánico y constituye una aproximación de primer orden que, necesariamente, debe actualizarse en las condiciones concretas del proceso eruptivo. Por su propia naturaleza, esta información no puede ser usada como herramienta para la toma de decisiones en materias de ordenamiento territorial o evaluación ambiental. Este documento no ha sido sometido a los mecanismos formales de edición del Servicio Nacional de Geología y Minería. LEYENDA Alto Peligro: Representa el sector más susceptible de ser afectado por procesos eruptivos en el entorno inmediato del edificio volcánico, independientemente de la magnitud eruptiva. Corresponde a los sectores superiores del complejo volcánico y a un área limitada en torno a los principales cursos fluviales. Engloba la totalidad de las lavas emitidas en la etapa tardía del volcán, depósitos de corrientes piroclásticas de extensión limitada y depósitos laháricos de pequeño volumen. Medio Peligro: Representa el sector más susceptible de ser afectado por procesos eruptivos derivados de erupciones de mediana a alta magitud en el edificio principal. Corresponde al sector inferior del complejo volcánico y a un área limitada en torno a los principales cursos fluviales. Incluye la mayoría de las lavas emitidas en la etapa temprana del volcán, flujos piroclásticos de mediana extensión, gran parte de posibles depósitos de avalancha volcánica y lahares de mediano volumen. Bajo Peligro: Representa el sector más susceptible de ser afectado por procesos eruptivos derivados de erupciones de magnitud alta en el edificio principal. Corresponde a las regiones más externas del edificio volcánico y a un área limitada en torno a los principales cursos fluviales. Icluye la totalidad de los posibles depósitos de avalancha volcánica, flujos piroclásti- cos de gran extensión y zonas de inundación por lahares de gran volumen con su respectiva fase diluida.

CUADRO DE UBICACIÓN
NOTA IMPORTANTE
Este documento forma parte de una serie especial de mapas de peligro volcánico cuya finalidad esproveer información sintética de carácter orientativo para su uso en situaciones de crisis. La zonificaciónpresentada es el resultado integrado de un análisis cuantitativo que considera múltiples escenarios erupti-vos escogidos de acuerdo a los antecedentes geológicos de este centro volcánico y constituye unaaproximación de primer orden que, necesariamente, debe actualizarse en las condiciones concretas delproceso eruptivo. Por su propia naturaleza, esta información no puede ser usada como herramienta parala toma de decisiones en materias de ordenamiento territorial o evaluación ambiental. Este documento noha sido sometido a los mecanismos formales de edición del Servicio Nacional de Geología y Minería.
L E Y E N D A
Alto Peligro: Representa el sector más susceptible de ser afectado por procesos eruptivosen el entorno inmediato del edificio volcánico, independientemente de la magnitud eruptiva.Corresponde a los sectores superiores del complejo volcánico y a un área limitada en torno alos principales cursos fluviales. Engloba la totalidad de las lavas emitidas en la etapa tardíadel volcán, depósitos de corrientes piroclásticas de extensión limitada y depósitos laháricosde pequeño volumen.
Medio Peligro: Representa el sector más susceptible de ser afectado por procesos eruptivosderivados de erupciones de mediana a alta magitud en el edificio principal. Corresponde alsector inferior del complejo volcánico y a un área limitada en torno a los principales cursosfluviales. Incluye la mayoría de las lavas emitidas en la etapa temprana del volcán, flujospiroclásticos de mediana extensión, gran parte de posibles depósitos de avalancha volcánicay lahares de mediano volumen.
Bajo Peligro: Representa el sector más susceptible de ser afectado por procesos eruptivosderivados de erupciones de magnitud alta en el edificio principal. Corresponde a las regionesmás externas del edificio volcánico y a un área limitada en torno a los principales cursosfluviales. Icluye la totalidad de los posibles depósitos de avalancha volcánica, flujos piroclásti-cos de gran extensión y zonas de inundación por lahares de gran volumen con su respectivafase diluida.
Número de habitantes zona alto peligro : 150 hab. (INE, 2002)Número de habitantes zona medio peligro : 2082 hab. (INE, 2002)Número de habitantes zona bajo peligro : 3572 hab. (INE, 2002)
