The western flanks of Cerro Chato on the SE side of Arenal are seen here from the OVSICORI-UNA/Smithsonian Institution volcano observatory at Arenal in 1998. At this time, the last known eruption was about 3,500 years ago. Following that eruption, it contained a 500-m-wide summit crater that is partially filled by Laguna Cerro Chato.
