San Salvador; Nejapa-Chiltepe (Apoyeque), El Salvador, Nicaragua, 2021

Figure 5 in: Bevilacqua, A., Aravena, A., Neri, A., Gutiérrez, E., Escobar, D., Schliz, M., Aiuppa, A. & Cioni, R. (2021). Thematic vent opening probability maps and hazard assessment of small-scale pyroclastic density currents in the San Salvador volcanic complex (El Salvador) and Nejapa-Chiltepe volcanic complex (Nicaragua). Natural Hazards and Earth System Sciences, 21(5), 1639-1665.



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.
