Mt Etna Volcano, Italy - John Seach

Lava fountains occurred at SE crater, Mt Etna on the night of 12-13 January 2011. The eruption consisted of a sustained lava fountain, lava flow, and an ash column reaching several kilometres high. The lava fountain lasted 42 minutes from 22:48-23:30 hr on 12th January and reached a height of 300-500 m. The lava fountain became pulsating after this time and reached a height of 100-200 m until 0:55 hr on the morning of 13th January. Ashfall was reported on the south flank of Mt Etna. The eruption was preceded by smaller episodes of Strombolian activity from SE crater on 23rd December 2010, and the evening of 2-3 January 2011. A lava flow descended the western slope of the Valle del Bove in three branches and reached the base after midnight. The longest flow surrounded the northern side of Monte Centenari, 4.2 km from the vent. On the 13th January ash emissions were caused by a partial collapse within the cone and eruptive activity.
