Geologically, the Caspian Sea, like the Black and Mediterranean seas, is a remnant of the ancient Tethys Ocean. The deepest area is oceanic rather than continental crust. However, it is generally regarded by geographers as a large endorheic salt lake. Of these registered lakes; 10 have a deepest point above the sea level.
Caldera lakes in contrast can be quite large and long-lasting. For instance, Lake Toba in Indonesia formed after its eruption around 75,000 years ago. At around 100 kilometres (62 mi) by 30 kilometres (19 mi) in extent and 505 metres (1,657 ft) deep at its deepest point, Lake Toba is the largest crater lake in the world. [4]
