Background

Volcán Santo Tomás (also known as Volcán Pecul) is a large eroded stratovolcano located across a valley SE of Santa María volcano. The summit is capped by late-Quaternary andesitic tephra. A winding ridge connects it to Volcán de Zunil, 4.5 km NE, a stratovolcano that forms the topographic high point of the Santo Tomás-Zunil complex. Solfataras and thermal springs are located on the ridge's W side. Volcán de Zunil is located on the SW rim of the 4-km-wide, 600-m-deep Tzanjuyub caldera, which is breached to the S by the Río Masa. Several dacitic-rhyolitic lava domes are located on the caldera's N flank and the NW flank of Volcán de Zunil. The youngest dome, Cerro Zunil, was last active about 84,000 years ago (K-Ar dating). No Holocene eruptions at Santo Tomás are known, although the volcano was included in the Catalog of Active Volcanoes of the World (Mooser et al., 1958) based on its geothermal activity.
