[Geology2] Mt Etna volcano, Italy

Eruptions have occurred at Mt Etna volcano, Italy. On the evening of 11th January 2011 an increase in volcanic tremor was recorded at the volcano. Seismic activity reached a peak at 07:00 hr on 12th January when the source moved from north of NE crater to the SE crater. This corresponded to weak eruptive activity at SE crater on 11th January. On 12th January eruptions increased with strombolian activity recorded at SE crater. About 21:00 hr, lava overflowed the eastern rim of SE crater, and fed a flow that moved toward the western wall of the Valle del Bove. The ash from the two-hour eruption forced the closure of Catania's Fontanarossa airport overnight affecting a few domestic flights. The volcanology institute in Catania, eastern Sicily, said today the eruption sent a little stream of lava down the eastern slope of the mountain. Nobody was injured. Officials said the airport reopened early today.
