Galapagos Islands volcanoes
Acedo volcano
Volcan
Alcedo is located in the center of Isabela, (also known as Albermarle
Island) located between Volcan Darwin to the north and Sierra Negra to the
south.
The composition of its lavas differs from that of both its neighbors,
indicating it has an independent magma plumbing system. It quite symmetrical
and rises to an elevation of 1100 m (3650 feet). Relative to its size and
height, Alcedo's caldera is large (7 to 8 km in diameter) and shallow (270 m
deep).
Darwin volcano
Volcan
Darwin is the second volcano south on Isabela, located between Volcan Wolf
to the north and Volcan Alcedo to the south. It is nearly perfectly
symmetrical and rises to an elevation of 1325 m (4350 feet) and is the fifth
highest volcano in the Galapagos.
Like the other western volcanos, it has a
large central caldera, nearly 5 kilometers (3 miles) in diameter and 200 m
deep (700 feet). A number of young lava flows may been seen within the
caldera, as well as on the flanks of the volcano.
