Photo Gallery

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.

Lava flows line the steep walls of a pit crater on Santa Cruz island. Note the person standing on the rim at the right for scale. Pit craters are formed by collapse following the withdrawal of magma along a rift zone. They differ from other craters in that their rims lack a mantle of explosive debris. In some cases, vertical-walled pit craters can be hundreds of meters deep.

The broad shield volcano forming Santa Cruz Island is seen from its northern coast. The oval-shaped, 32 x 40 km wide island is capped by cinder cones with well-preserved craters that largely bury a shallow summit caldera. The highland scoria cones are grouped along an E-W belt parallel to recent fault scarps that border Academy Bay, location of the Charles Darwin Research Station.
