Abstract

Hazards in monogenetic volcanic fields include processes and events occurring prior to, during, and after an eruption. This contribution identifies hazards resulting from processes occurring prior to and after a volcanic eruption. From recent experiences in the Chichinautzin volcanic field, hazardous events associated with reports of potential impending eruptions have turned out to be three types of false alarms: fires or gas explosions in sanitary landfills, underground fires, and anthropogenic lava flows. Typically, people who live at monogenetic volcanic fields know that an eruption is a likely event, so when they observe deformation of the ground, heat flow, and explosions, they report these anomalous events to the authorities as volcanic. A methodology should be established to cope with reports of new volcanic activity and to handle the outcome, which could be volcanic or nonvolcanic hazards. The hazards related to events occurring after an eruption include the planning of cities and villages around tube systems, building hazards over lava tubes, pollution due to sewage release in lava tube systems, with consequences to public health and the environment, and endangering threatened species that live in the volcanic systems after the eruptions. Here, we propose a view of volcanic hazards that has not been made before and is distinct from the usual hazards evaluation during eruptions.
