Topo Volcano
Inactive shield volcano on Pico Island, Azores
From Wikipedia, the free encyclopedia
Topo Volcano (Portuguese: Vulcão do Topo) is an inactive shield volcano located on Pico Island, Azores. The volcano measures 1,002 m (3,287 ft) 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 (2,000 ft) thick superposition of alternated Pāhoehoe lava flows and thin layers (10%) of pyroclastic material.[4][1][3][2]
