Volcanic tremor as of 16h10 GMT 8 Feb (INGV Catania)
Update 20h15 GMT:
Tremor continues to rise (now at 13), from the webcam image, it seems a lava flow is starting to issue from the SE fracture.
Update 19h GMT:
All indicators point towards we are having the 2nd paroxysm in 2012 during the next hours!
The volcanic tremor is now steeply rising (at 8) and vigorous strombolian activity can be seen on the various webcams, possibly a lava flow has started as well.

While strombolian activity continues from the New SE crater of Etna volcano, volcanic tremor has started to rise, suggesting a new paroxysm could be in the making in the next hours, although it is still early to be certain.
The photo (left) from Boris Behncke was taken during the night of 7-8 February 2012, whe the continuing Strombolian activity of the New Southeast Crater on Etna was finally widely visible, after about one week of essentially bad weather.
Some explosions threw incandescent lava bombs outside the crater, although most were rather weak and all material fell back into the crater.
This is a view of one of the stronger explosions observed on the late evening of 7 February 2012, taken from Trecastagni village on the southeast flank of Etna. The activity continued, sometimes vigorously, sometimes more subdued, through the night and morning of 8 February.

Etna volcano (Italy): sporadic strombolian explosions from New SE crater

Sporadic strombolian eruptions continue from the New SE crater of Etna, but - in contrast to previous such episodes - no new paroxysm has yet occurred. The volcanic tremor shows a slightly increasing trend with more fluctuations than normally.
What Etna will do next, is still her secret.
Etna volano (Italy), activity update: new strombolian activity, new paroxysm could be in the making

Strombolian activity caught on one of the webcams of Etna (thanks to Vanessa B. on facebook)
New strombolian activity from the New SE crater has been observed from webcams, together with a fluctuating, but overall slightly rising tremor signal in the past hours. Whether this is the start of a new paroxysmal eruption will probably be clearer during the next hours or tomorrow.

The photo was taken in spring 2009 and shows an explosion from Stromboli's NE crater in the evening twilight. In the first half of 2009 in particular, this crater was in spectacular, vigorous activity. It had quickly built a tall cone, changing and dominating the crater terrace of Stromboli, and although more changes have happened, it is still one of the main features of the crater today. ... [more]
