Lava flow at night. Night view of a bright lava flow on the flanks of Etna. The lights in the background reveal the city of Catania about 16 kilometres away. Etna is Europe's largest active volcano, and dominates the eastern coastline of Sicily. Despite almost constant, gentle Strombolian activity releasing its internal pressure, Etna also has periodic episodes of intense lava production. Photographed in May 1999.
