Since the early morning of December 19, the seismic network of the INGV-Sezione di Catania recorded a significant seismic swarm constituted, at the moment, of about 30 earthquakes. The most energetic earthquakes occurred at 6.36 AM (Local Time; GMT+1) and at 10.01 AM (Local Time; GMT+1) with a magnitude of 4.3 and 4.6 respectively as well as depths of hypocenters at 16 and 14 km respectively.

The activity at the South East Crater (SEC, 3340 m a.s.l.) was recently characterized by lava flow emission together with explosive paroxysms, the most violent of which occurred on November 16, 2006 accompanied by collapses of the eastern sector of SEC.

 During the last days, the eruptive activity of the pit-crater located at the eastern base of the South-East crater continues to be characterized by low-intensity strombolian explosions mostly intra-crateric. Some phases of slightly more intense activity are observed, with explosions that eject incandescent material few meters above the crater edge.
An increase of the degassing both at the summit craters (especially the Bocca Nuova) and at the pit-crater at the base of the South-East crater (affected by pulsating degassing) was observed on November 26.
Further details or significant changes in the behaviour of the eruptive activity will be promptly provided in following reports on the website. |

During the last week, the good weather conditions allowed to continuously verify the state of the eruptive activity, which started on the evening of November 6, 2009. With respect to the last survey in the summit area, the activity of the pit-crater located at the eastern base of the South-East crater shifted to be slightly more explosive and continuous. The low-intensity strombolian explosions generally eject incandescent material few meters above the crater edge, with some, more rare, vigorous explosions which emit material about 10 meters above the crater edge. Further details or significant changes in the behaviour of the eruptive activity will be promptly provided in following reports on the website. |
