The massive Hierro shield volcano is truncated by a large NW-facing escarpment, seen here from the east, which formed as a result of gravitational collapse of the volcano.  The steep-sided 1500-m-high scarp towers above a low lava platform bordering 12-km-wide El Golfo Bay, which is barely visible at the extreme left.  Holocene cones and flows are found both on the outer flanks and in the El Golfo depression.  The latest eruption, during the 18th century, produced a lava flow from a cinder cone on the NW side of El Golfo.
