Today's eruption video (August 20) at Etna volcano (Sicily, Italy) + video other eruptions

Eruption update  20/08-16:31 UTC : 11th Paroxysm at Etna was videotaped on the morning of August 20 2011 by Klaus Dorschfeldt.  Enjoy the this mornings eruption. Paroxysm eruption : if the volcano violently erupts or spews up ash or shoots up lava, in other words it is having a violent outburst, then that is the paroxysmal phase.

New eruption on July 31 2011 (1) Fountains of fire. Enjoy the extraordinary beautiful  scenes.
The video has been shown on EuroNews  "No Comment"
Mount Etna erupted for the eighth time this year. The progress of the eruption has been always the same: starting from a weak strombolian activity, turning into a lava fountain, reaching almost 500 meters and the lava following the line of the previous paroxysms, flowing inside Valle del Bove.

New eruption on July 30 2011 (2). An this a second video shot on July 30.  It is a PassioneEtna video with a lot of video footage from another angle and with more than fire fountains.

UPDATE 10/07 -  09:45 UTC :  Due to the volcanic activity and the ash concentration in the air, the (important) regional airport of Catania was closed since yesterday 18:12 (6:12 PM). The airport reopened this morning at 07:00 ( 7 AM).

UPDATE 08:00 UTC : As stated below, the densely populated Catania area got a lot of ash showers covering cars and roofs with a gray layer.

UPDATE : One video tells more than a 1000 words. This YouTube video was recorded by Klaus Dorschfeldt alias KdEtna. We encourage our readers to take a look at his great Etna Channel on YouTube.  The strong eruption was short-lived  (see in-depth text below), which explains why there are only daylight videos from this eruption

A few days after the resumption of Strombolian activity at the crater located on the east flank of the Southeast Crater cone, a new paroxysmal eruptive episode has taken place on the afternoon of 9 July 2011.

This was the fifth eruptive episode since the beginning of 2011, and it was of shorter duration than its predecessors, but it produced ash and lapilli falls over the most densely populated area on Etna as far as Catania.

From 4 to 7 July, the active crater has been the site of weak Strombolian activity, which from the evening of 7 July on showed a gradual increase; this was accompanied by a slow augmentation of the volcanic tremor amplitude.
Small pyroclastic cones began to grow on the crater floor. The next morning, the increase in the intensity and frequency, and in the volcanic tremor amplitude, showed a clear acceleration, which seemed to indicate an imminent paroxysm. However, shortly after 06:00 GMT, the volcanic tremor amplitude showed an abrupt diminution, and the Strombolian activity at the active crater completely ceased.

On the morning of 9 July, Strombolian activity resumed, and the volcanic tremor amplitude started to rise rapidly. Shortly after 12:00 GMT, lava overflowed the eastern rim of the crater, and then followed the path of the lava flows emitted during the previous paroxysms. At 13:45 GMT the Strombolian explosions blended into a continuous lava fountain, which was accompanied by the formation of a dense eruption column several kilometers high. The eruption plume, which was heavily charged with tephra, expanded south- and southeastward, leading to ash and lapilli falls in the populated areas between Nicolosi and Catania toward south, and Trecastagni, Viagrande and Acireale toward southeast.

The paroxysmal activity lasted little longer than one hour, feeding a lava flow into the upper western part of the Valle del Bove, and generating strong emission of pyroclastic material; the activity showed a progressive diminution shortly after 15:30 GMT when volcanic tremor amplitude dropped to very low levels.

It has finally to be noted that during the intial phase of the paroxysmal activity, at 13:41 GMT, a powerful explosion at the Bocca Nuova generated an intense ash emission.
