For their part, the rural areas of the municipalities villamaria (Kaldas), herveo, casabian, beautiful villa, murillo (Tolima) and Saint Rose of Cabal (Risaralda) may present “the fall of metric-sized rock fragments launched with a ballistic trajectory that can affect a radius of up to about 4 km around the crater”.
