Cerro Negro is the most recent basaltic cinder cone to form in the western hemisphere. The most recent eruption was in May-August 1995. The 1968 eruption is shown in the above U.S. Geological Survey photograph. The cinder cone was 750 feet (230 m) tall at that time. Note that the cone rests on older lava flows. Most eruptions at Cerro Negro produce both pyroclastic material and lava flows.
Cerro Negro has erupted at least 20 times since 1850. The longest eruption was in 1960 and lasted 3 months. Photograph of a 1968 eruption at Cerro Negro copyrighted by Robert Decker.
