On November 28 I was alert
Volcanic Tremor variation during the last Etna eruptive paroxysm
Lava fountains activity on Etna volcano as seen trough the clouds (November 28, 2013 at 21:31 [UTC +1])
Steam ring at right of fountain. This image could be better, but please take in mind that the shotting place was about 15kms far away from the crater.
