STEPHEN FRAZIER, CNN ANCHOR: Fire and brimstone from atop one of Europe's most active volcanoes. Mount Etna stands nearly 11,000 feet over Sicily. And for the past two weeks, molten lava and ash has been spewing from the volcano's mouth. It's breathtaking, but it's dangerous. Emergency crews are working to keep boiling lava from reaching tourist areas now. Meanwhile, ash has forced the closure of Sicily's main airport. For more on Mount Etna's eruption, we're joined on the phone by professor Enzo Boschi, president of Italy's National Institute of Geophysics and Volcanology, who is calling us from Catania, Sicily.

We are trying to divert the lava from the buildings. And if the lava maintains its volume, we will be able to save these buildings, but if the lava is going to increase, it will be nearly impossible. Everything will be decided by the volcano.</s>FRAZIER: Everything decided by the volcano, not by mankind. Professor Boschi, thank you for explaining that to us, and good luck.</s>BOSCHI: Thank you very much.
