Etna erupted again last night, the fifth eruption in a week. It generated lava jets up to a thousand metres high above the South-East crater. The activity produced an eruptive column that rose several kilometres above the top of the mountain. At the same time, two small lava flows formed, one in the direction of the desert Bove Valley and the other in a south-westerly direction.
A new paroxysmal activity occurred yesterday morning on Etna. In this case too, it affected the South East Crater, where high lava fountains appeared. The new phenomenon was preceded by a lava overflow, with the flow then heading towards the deserted Valle del Bove.
The eruptive cloud produced by the explosive activity then dispersed in an east-southeast direction causing ash fallout.
Etna returns to erupt, recording a strong explosive activity from the South-East crater and the emission of a high cloud of lava ash that has dispersed to the south. From the same “mouth” emerged a lava overflow that has given rise to numerous phenomena: lava fountains, a giant cloud of ash above the mountain and volcanic lapilli arrived up to Catania. The column of smoke is visible from over a hundred kilometers. However, it seems that the event is not particularly worrying from the point of view of public safety: the lava fountains have reached a height of many hundreds of meters, but the lava flow is directed as usual to the Valle del Bove, a high altitude basin far from any inhabited center.
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.
Finally today we return to WATER!
After months in the dry, the sensations experienced underwater are indescribable, the happiness that shone on our faces, the immense joy of being in nature, are worth a thousand words.
We found a luxuriant marine ecosystem, a long period of quiet, no or very few human activities have meant that marine biodiversity has benefited greatly. For many years we had not observed such a luxuriant indigenous algal cover rate, so many sea urchins, molluscs and the most diverse fish species! Now it’s up to us to continue the path that nature has shown us.
Happy Bubbles Divers friends of the globe!
Surely you remember the lava of 1991/93! The destination of our daily tours!
Soon we will return to explore our Etna. Your company our Etna.

This five-minute video summarises the entire chronicle of the 1991-93 eruption of Mount Etna, which threatened Zafferana Etnea, with particular attention to what was known as the “Operation Cap”, which consisted of an attempt to interrupt the course of the lava with the use of dynamite, causing it to overflow into a channel.
The video is taken from the DVD “Il gigante di fuoco” (The Fire Giant) released in 2008.
Big pictures and big bangs! Original sounds!
