More and increasingly larger (and hence more dangerous) pyroclastic flows are being formed by the growing lava dome of the volcano. These "flows" are hot turbulent avalanches of hot blocks and ash in suspension with hot gas and air, that can travel down at great speed the slopes of the mountain, typically following the paths of valleys.

Weak lava fountain at the New SE crater

Etna (Sicily, Italy): The 21st paroxysm at the New SE crater which started last evening is still going on although it has decreased a bit. Until now, the eruption has been rather weak with no sustained tall lava fountains as during most of the paroxysms. Instead, the New SE crater continues to produce loud, spectacular near-continuous strombolian-type jets (or low, pulsating fountains) and explosions of lava bubbles. The eruption so far: Read all

This morning at 11:16 (local time), an ash explosion occurred from the New SE crater, accompanied by a rise in tremor. This is similar to the precursory activity of the recent past paroxysms and probably means that the magma column inside the cone's conduit has started to rise and began to clear its way by sporadic, but potentially quite powerful explosions.

An increase in activity was indicated by the volcano observatory today. The explosions (strombolian type) at the summit vent occur now at rates of 6-8 per hour and lava effusion increased. Currently, the lava flow is headed towards the Cenize canyon on the SW side. It is a possibility that this activity continues to build up towards another paroxysm, in which case the occurrence of pyroclastic flows (mainly by collapsing lava flow fronts) is a likely and dangerous scenario.

Fri, 13 Dec 2013, 06:20

Tremor has started to increase this morning, although so far, no visible activity at the New SE crater has appeared while strong degassing from the NE crater continues. The next hours will probably show whether the volcano is going to prepare its next paroxysm in the near future or not.
