Etna strombolian activity of the southeast crater

Etna does not stop and since tonight has begun again to erupt lava fountains from the South-East Crater. The National Institute of Geophysics and Volcanology, Etnean Observatory, explained that since the early hours of February 15 has been observed a gradual intensification of explosive activity at the Southeast Crater. While the activity is continuous at the eastern mouth of the same crater, have been observed sporadic and sometimes violent explosions at the “mouth of the saddle”. Continues – always explains the Ingv – the intracraterial explosive activity in the craters Bocca Nuova, Voragine and Northeast. Relative to the average amplitude of the volcanic tremor this had already shown by the early hours of this morning a tendency to increase. From about 16 hours has been recorded even a more significant increase. The source of the tremor is located below the SE Crater, at a depth of about 2900m. The infrasonic activity appears to be high, both for the frequency of occurrence of infrasonic transients and for their amplitude.
