Spatial probability analysis for the CLV. PDFs obtained for each volcano-structural dataset after applying the kernel density estimation method and shown as probability isocontours. a Volcanic vents, where an age-weighting procedure was used in order to give higher weights to newer vents (white triangles indicate the location of historical eruptions). b Thermal anomalies. c Earthquake epicentres. d N-S structures. e NE-SW structures. f E-W structures. g NW-SE structures. h Combined PDF showing the spatial probability of vent opening, obtained by weighting each volcano-structural layer based on its relative importance in controlling the distribution of volcanism in the region. Each map is drawn at 1:500,000 scale
