INGV reported that at around 1900 on 12 May new vents opened along the N flank of Etna?s Southeast Crater (SEC) and produced ash emissions that rose to 3.5 km (11,500 ft) a.s.l.
and drifted SW.
Lava flowed from the vents and traveled to the N base of the crater.
Lava effusion continued over the next several days, and by 17 May the flow had descended ENE into Valle del Leone, reaching 2,300-2,400 m elevation.
Discontinuous Strombolian activity of variable intensities occurred at SEC; during more intense phases ash emissions were visible, though the plumes dissipated rapidly.
