From Wikipedia
Alcedo Volcano is one of the six coalescing shield volcanoes that make up Isabela Island in the Galapagos. The remote location of the volcano has meant that even the most recent eruption in 1993 was not recorded until two years later. It is also the only volcano in the Galapagos to have erupted rhyolite and basaltic lava.
