La Cumbre volcano, Fernandina Island Galapagos

La Cumbre volcano, Fernandina Island, Galapagos. To illustrate how quickly a crater lake can change, this was photographed by astronauts aboard the International Space Station in 2002. But this crater lake has returned to its explosive beginnings. Wikipedia stated that it began erupting again in April 2009. It’s now the most active volcano of the Galapagos Islands.
