The highlands of the broad Santa Cruz shield volcano, seen here from the NE, are capped by youthful cinder cones with well-preserved craters. The scoria cones are grouped in an E-W belt parallel to recent fault scarps that border Academy Bay and largely bury a shallow summit caldera. Older uplifted submarine lava flows are found on the NE part of the island and at the fault-delimited offshore island of Baltra. No historical eruptions are known from Santa Cruz, the 2nd-most populated island of the Galápagos archipelago.
