Eruption of the Etna September 2007 |
|
Mount Etna eruption updates for 4-5 September: For all the night, in the depression on the east flank of the crater of S-E, is in course an intense and spectacular strombolian activity with lava fountains that catch up a height of several hundreds of meters. A small tap of lava heads towards the Bove Valley. Moreover present is an ash column of approximately two kilometers that go towards east on Fornazzo and Milo.
It's for the ash that it has been decided, beginning from 1:00 Am of this night, the closing of the airport of Catania.
The 29 August on the east flank of the south-east crater has been recorded an elevated frequency of strombolian outbreaks. Such outbreaks are not compatible with an increasing of magma flow but with collapses produced by an emptying of a superficial magmatic tank.  The investigators of the national institute of Geophysicist and volcanology (http://www.ct.ingv.it) have directly observed the collapse that in its inside shows a slag cone. The explosive activity is accompanied by ash emission.
