Pinta Volcano — Ecuador

The elongated island of Pinta is a shield volcano with numerous cones and lava flows originating from NNW-trending fissures. A steep sea cliff truncates the W flank. The unvegetated lava flows that cover the SE and N flanks appear to have been erupted during the past few thousand or few hundred years (McBirney and Williams, 1969). Although an eruption was reported in 1928 (U.S. Hydrographic Office, 1938), no description or source of that event is given, so it is considered uncertain; no confirmed or dated eruptions are known.
