In this pictures made available Thursday, Jan. 13, 2011, lava overflowing from the eastern rim of the erupting pit crater of Mount Etna, Sicily, Wednesday, Jan. 12, 2011. Italy’s Mount Etna has come back to life with a brief eruption that sent lava down its slopes and a cloud of ash into the sky, forcing the overnight closure of a nearby airport. The volcanology institute in Catania, eastern Sicily, said Thursday that a two-hour eruption overnight sent a little stream of lava down the eastern slope of the mountain. Nobody was injured.
