Title: Lake Ilopango, El Salvador
Caption: View from space of El Salvador's Ilopango Lake, which is also a caldera. Calderas are the geologic record of powerful volcanic eruptions that empty out a volcano's magma chamber; following the eruption, the overlying volcanic structure collapses into the newly formed void, leaving a large crater-like feature (the caldera).
