Geological summary
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.
From Wikipedia
Nevado de Santa Isabel is a shield volcano straddling the boundaries of the Colombian departments of Tolima, Caldas, and Risaralda, being the highest point of the latter. The volcano lies approximately 10 kilometers southwest of the larger Nevado del Ruiz volcano. Santa Isabel is the third highest peak in Los Nevados National Natural Park. It is a relatively flat volcano with three domes of nearly equal elevation.
