Illustrative example of a three-color hazard map of Tungurahua volcano, constructed by considering the 50% isoprobability curve of the maximum probabilistic hazard map of each scenario

Tungurahua, Ecuador, 2024

Figure 10 in: Aravena, A., Tadini, A., Bevilacqua, A. et al. Probabilistic, scenario-based hazard assessment for pyroclastic density currents at Tungurahua volcano, Ecuador. (2024). Bulletin of Volcanology 86, 84. https://doi.org/10.1007/s00445-024-01768-y



This hazard map is the result of scientific research and was published in academic literature. It is presented here to serve as an example of the map type or the map-making methodology. It is NOT the official, operational map. For the current operational hazard map, please consult the proper institutional authorities.
