Isla Zacate volcano (or Isla Zacate Grande) is a stratovolcano that forms a low 7 x 10 km wide island in southern Honduras separated by a narrow strait from and surrounded by the Gulf of Fonseca and Chismuyo Bay.
The mainly basaltic volcano is strongly eroded with deep erosion valleys on the summit cone, suggesting it has not erupted for a long time.
Zacate Grande volcano contains at least 7 flank cones, some of which form small islands offshore. Some of these, including the symmetrical cone of Isla Gueguensi in the tidal flats about 3 km east of the base of Zacate Grande, have probably been active during the past 10,000 years.
