Summary

Description
English: The volcano’s most distinctive feature, its nine-kilometre wide caldera, Cha Caldera, is shown in this image. The crater wall in the west towers one kilometre above the crater floor. The eastern half of the crater wall is gone, erased in a massive collapse deep in its ancient history. Evidence of the volcano’s more recent eruptive history is written on the surface of the crater as well. In the centre of the crater, a steep cone named Pico rises about 100 meters above the crater rim (more than a kilometre from the crater floor). The young peak reaches 2,829 meters above sea level, making it the island’s highest point. Dark trails of hardened lava from the volcano's most recent eruptions stream out of the crater east into the Atlantic Ocean. The volcano last erupted in 1995. The sepia stream of lava from that eruption is pooled near the crater rim west of Pico. Remarkably, the crater is inhabited. A straight road cuts between the crater wall and Pico, ending near the vent that erupted in 1995. Bright white dots on the north side of the crater are villages. Residents of the Cha Caldera evacuated during the eruption.
