Strombolian activity at the SE crater and lava emission from vents inside the crater continue at Etna volcano. Parts of the cone are collapsing, permitting viscous lava to flow out from the center.
The following in a detailed report published by the INGV Catania:

Weak strombolian activity is ongoing at the SE crater. On the evening of 4 Sept. 2006 a fracture opened inside the crater and started to emit a lava flow into the collapse pit at the east flank of the cone.

This morning at around 8:30 am local time, new eruptive activity was first observed at the SE crater of Etna volcano, which had had its last brief eruption in late July. The onset of new strombolian activity had been preceded by a seismic swarm at around 11pm last night.

The strombolian activity from NE crater is no longer visible, as the magma column has dropped again inside the conduit. (-->So, the worrying question is, where is all that magma going ... into some new flank intrusion?)

The effusive eruption from the fissure at the base of the SE crater ended on 24 July. Shortly after, mild explosive strombolian activity started at the NE crater as observed since 26 July.
The recent lava flow field emplaced on the west wall of the Valle del Bove had reached the base of Monte Centenari at 1800 m a.s.l.

The explosive, mild strombolian activity at the 3100m vent is continuing and about to form a new scoria cone. The lava flows from the two other vents at 3050 and 3000m elevation form a branching lava flow whose lowest front is now at 2100m elevation in the upper part of the Valle del Bove. The estimated eruption rate is 2,6 m3/sec and the total volume erupted so far is estimated about 800,000 m3.

Lava flow from Etna volcano

Etna's eruption continues at a mild rate. INGV has estimated the output rate of lava to be around 2.4 cubic meters per second. There are 3 eruptive vents close to each other at the SE base of the SE cone, one at 3100m (only mild strombolian explosive activity, in diminuition as of today) and two effusive vents at 3050 and 3000m elevation. The two lava flows from the lower vents merge about 100m from their source and the lava flow is entering the upper areas of Valle del Bove, reaching 2400m elevation as of today. More on Etna

Etna erupts again.
As David Corsaro (hotel owner on Etna, www.hotelcorsaro.it) reports to us, the eruption started during the previous night (between 14-15 July, 2006) from two fissure vents at the SE flank of the SE crater cone at 2900 m elevaion. Two moderate lava flows are emerging from the vents, both entering the Valle del Bove. The longest of the two flows has reached 2500 m elevation.
The eruption appears to be a similar event as the last one that had started in Sept. 2004 and lasted until March 2005. There is no danger for inhabited areas.

Etna continues its worrying slumber. After an isolated phreatic explosive event in January, the diafragma separating Bocca Nuova crater and the Voragine (the former Central crater) as well as the wall separating the two craters inside Bocca Nuova have mostly collapsed, leaving what is now best described as one single central crater with several pits and vents at considerable depth.
Several VolcanoDiscovery groups visited Etna on various occasions over the past weeks, and found strong degassing taking place from fractures in the walls and the bottoms of the various vents inside the central crater, as well as audible but deep-seated explosive activity inside North-East crater.
