Volcán Santo Tomás (also known as Pecul) is the sharp peak on the right-center horizon rising above the Pacific coastal plain. A winding ridge connects Santo Tomás to Volcán de Zunil, 4.5 km to the NE, a 3542-m-high stratovolcano that forms the topographic high point of the complex at the extreme right. No Holocene eruptions are known from Santo Tomás, although there are active solfatara fields. An eruption plume rises from Santiaguito lava dome on the flank of conical Santa María volcano, across the Río Samalá to the west.
