Tecuamburro, seen here from the north, is a small, forested stratovolcano or lava-dome complex of mostly Pleistocene age. The smoother, left-hand side of the elongated volcano consists of younger lava domes that were constructed during the late Pleistocene or early Holocene within a horseshoe-shaped, east-facing caldera. The caldera resulted from structural failure of the older Miraflores stratovolcano (right). A phreatic tuff ring on the NW flank, Laguna Ixpaco, is of Holocene age, and is still fumarolically active.
