The middle unit of the La Vírgen Plinian fall deposit displays a massive structure (lacking internal structure) with large pink pumice fragments. This deposit, more than 1 km³, is the product of a major explosive eruption that occurred from Tres Vírgenes volcano. The dispersal axis of this airfall deposit was to the SW. The eruption also included the emplacement of pyroclastic flows and voluminous lava flows.
