[ link to www.wired.com] Boris Behncke 6 hours ago ... I am starting to focus increasingly on the impact of this activity on the people living around Etna, which is getting more and more dramatic. Many towns and villages, especially in the southeastern, eastern and northeastern sectors of Etna have repeatedly received heavy tephra fallout, and driving through these areas you are gradually invaded by a sensation of sadness, it's all black and dusty, there are incredible amounts of scoriae and ash piled up along roads, the colors of spring are suppressed, and people are reluctant to put much effort into cleaning up because too many times they had just cleaned up and a few hours later, everything was covered with a fresh layer of black pyroclastics. ... Etna now: signs of minor night activity and current heating [ link to www.ct.ingv.it] [ link to www.flickr.com] Black springpic [ link to farm9.staticflickr.com] ...This photo renders an idea of the problem - the black mounds in the foreground are heaps of tephra that were dumped on a little square at the northern margin of Zafferana Etnea after the repeated tephra falls of February-April 2013; this little square was originally part of a public park. There are scenes like this everywhere in the tephra fall sectors on Etna's flanks. And then there are other scenes, like the endless rows of tephra-filled plastic bags piled up along roads, which no one has so far thought of removing (because nobody knows where to put that stuff and what to do with it); in the meantime they have been covered with new layers of tephra by more recent episodes of lava fountaining. Overall, people seem to have resigned, because more than once they have made the experience that as soon as they have cleaned up their roofs, their terraces, and the sidewalk in front of their homes, there will be a new lava fountain and a new shower of pieces of black volcanic rock. Photo taken on the morning of 29 April 2013, looking south toward the center of Zafferana Etnea. [ link to volcans.blogs-de-voyage.fr] ...Boris added that the latest paroxysms have been different from most of those of the past, many of them have been much more explosive and also much more voluminous than those, for example, of the year 2000. […] “There is quite some concern about how things will go on, Etna is not showing the least sign of changing her behaviour in the foreseeable future …” I answered Boris that “as long as the volcano behaves this way, it is a good thing for the people who live in Santa Venerina, Zafferana , Nicolosi and so on. The volcano is dirty and forces people to sweep away the ash and clean their houses but it would be much worse if an eruption occurred on the lower slopes of the volcano! The current situation confirms what I concluded from my observations in the late 1990s. I was then convinced there was a shallow magma chamber beneath the SE part of the summit area. What I fear most today is that the current activity weakens the SE flank of the volcano and reactivates the fracture that crosses the SP 92 road. If it did, the situation would be quite different. » Let’s cross our fingers that the paroxysms or the eruptions remain concentrated in the summit area. It would be a real problem if vents or fissures opened at lower altitudes. The lava flows would rapidly become a threat to populated areas. Mount Etna has an eruptive history which shows that such events should not be excluded. We just need to remember the 1928 eruption that destroyed Mascali or the 1991-1994 eruption that started on the upper wall of the Valle del Bove and caused days of fear and anxiety to the inhabitants of Zafferana Etnea… Etna: after pause in few days again heating of cone [ link to www.ct.ingv.it]
