Pinta Island

Pinta

Shield volcano · Ecuador · 729m

The elongated island of Pinta is the northernmost of the active Galápagos volcanoes. This view from the summit of Pinta looks down on pyroclastic cones and lava flows on the southern flank of the shield volcano. Numerous young cones and lava flows originated from NNW-trending fissures cutting the island. The fresh, unvegetated lava flows that cover the SE and northern flanks appear to have been erupted during the past few thousand or few hundred years. The island in the distance is Marchena volcano.

Geological summary

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.
