Short summary

We present novel probability maps for the opening position of new vents in the San Salvador (El Salvador) and Nejapa-Chiltepe (Nicaragua) volcanic complexes. In particular, we present thematic maps, i.e., we consider different hazardous phenomena separately. To illustrate the significant effects of considering the expected eruption style in the construction of vent opening maps, we focus on the analysis of small-scale pyroclastic density currents using an approach based on numerical modeling.
