Etna (Sicily, Italy): (18 Feb) The intense effusive-explosive activity at the volcano continues.
The lava, emerging from the fissure at the southern base of summit craters, continues to advance on the western flank, currently about 4,200 meters long.
Increased and near-frequent ash emissions continue to be active from the Southeast crater, dissipating dominantly in the southeastern direction. As visible in the latest Sentinel-2 satellite acquisition from 17 February, the entire northeast-southwest area of the edifice is being covered by fine ash material due to the prevailing SE wind direction.
