Bulldozers work to construct a wall against the scalding river of lava creeping down the slopes of Mt. Etna, Sicily, Sunday, Nov. 24, 2002, toward the 'Rifugio Sapienza' a refuge for hikers and tourists. By evening, the lava had rolled down to about 250 meters from the complex. Rocked by two earthquakes (news - web sites) five minutes apart Sunday, frightened people raced out of their homes on Mount Etna's slopes, where a thick river of lava was rolling toward a refuge for hikers and tourists.
