Topo Volcano

Topo Volcano (Portuguese: Vulcão do Topo) is an inactive shield volcano located on Pico Island, Azores. The volcano measures 1002 m in height and occupies the southernmost area of the island. It is part of the Lajes (or Topo) Volcanic Complex, the oldest volcanic apparatus which gave origin to the island, around 300,000 years ago. The volcano was created by a 600 m thick superposition of alternated Pāhoehoe lava flows and thin layers (10%) of pyroclastic material.

Its land area is approximately 18 km2 but its total area, accounting for the sea floor and the area that gave rise to the Achada Plateau, is estimated to be around 120 km2.
