Wed, 6 Aug 2014, 06:00
06:00 AM | BY: VN
On 9 August INGV reported that volcanic tremor decreased and an ash plume rose to 1 km above the July 25 area of Etna and returned to strong Strombolian activity in the evening. Strombolian activity increased at New Southeast Crater that was accompanied by small emissions of black ash that remained within the crater. The Etna Volcanic Observatory raised the Aviation Color Code to Red on 9 August as an ash plume rose to 4 km (13,000 ft) a.s.l. returning to Orange on 10 August.
The Aviation Color Code was raised to Red on 11 August with strong Strombolian activity at Etna accompanied by significant ash.
