Beskrivning:

Volcán Barva (Barba), seen here from the Central Valley of Costa Rica, is a complex volcano with a broad summit containing three principal peaks and a dozen eruptive vents. Four pyroclastic cones are constructed within the central and NW parts of a 2 x 3 km caldera. The SW peak is capped by another 4 cones, one of which contains a crater lake. Satellitic cones are found on the northern and southern flanks. A large plinian eruption occurred at Barva during the early Holocene. There have been no confirmed historical eruptions.
