 During the night of 10 to 11 and the morning of 11 November , the Strombolian activity has evolved , giving , from 4:00, lava fountains, an ash plume dispersed to the northeast and three lava flows, the most voluminous was issued to the saddle between the two cinder cones , and moved southward.
 
The 15th paroxysm of 2013 lasted about seven hours and a half , very unfortunately obscured by clouds which prevented direct and webcams observations, between midnight the 10 and 9:00 the 11th .

If one has seen, the fountains were low rise , but the explosions very violent, with the formation of gas bubbles.
