Lights of Catania and Piano del Lago

Photo: Lights beneath an erupting Piano del Lago, Catania

Perched above the lighted city of Catania, Italy, Mount Etna hurls a fountain of fire skyward as rivers of lava spill down its flanks. In spite of its dazzling displays, Mount Etna is a relatively safe volcano with rare, compact eruptions and slow-flowing lava that gives people a chance to escape.
