The INGV reported that the active lava flow in the morning stopped, and a new cast is superimposed on the previous one, and has traveled to 13 hours GMT on half the distance on the west wall of the Valle del Bove ( from the images of the thermal imager of Monte Cagliato ) .

Boris Behncke pointed out that the amount of ash emitted increased in the afternoon of 26 January ... interesting event because product shortly after the earthquake of M 6.3 that hit the Greek island of Kephalonia, also felt in Sicily ( an imprint was left on the diagram tremor ) .

Etna - tracing of the tremor 2014.01.27 - the peak to the right of "M" is the trace of earthquake Kephalonia M 6.3 . - On 28.01, the level of tremor lowers - doc . INGV Catania

This emission of ash generated disturbances in Catania airport, where flights had to be diverted overnight.


Cloud cover obscured then the summit and prevented any vision by the webcams.
Short clearances helped to control on the new thermal webcam Monte Cagliato ( EMCT ) that the casting is still active.
 
Hot gas and steam still lag the NSEC .
The tremor is down in the 28th January (see chart above) .
