지질학적 요약

Santa Isabel is a small andesitic shield volcano that is dwarfed by its neighbors to the NE (Nevado del Ruiz) and SE (Tolima). Three lava domes occupy the elongated, N-S-trending glaciated summit region, which has two main peaks. Holocene lava flows fill valleys to the SW and SE. A small Holocene lava dome was emplaced at the center of a circular depression about 10 km SW. No historical eruptions are known.
