 16h00; 14mm. View towards Bocca Nuova (BN) from Southwest. Loud detonations were usually followed by massive ash emission. |  17h30; 135mm. BN lava flow shortly after sunset. Note the spattering where the flow starts. On the following day all flow activity stopped. |  17h40; 50mm. BN lava flow and intensive strombolian activity from BN's western vent. |  19h00; 50mm. BN lava flow and intensive strombolian activity (accompanied by loud detonations) from BN's western vent. |
 15h00; 14mm. View towards BN from the South. South East Crater (SEC) on the right. |  13h00; 14mm. Overview of SEC (upper left), tumulus and hornitos of the SEC lava flow (center right). |  14h00; 135mm. Spattering of a hornito below South East Crater (SEC). Vigorous effusive activity had re-started here just one day before. |  13h30; 35mm. At first lava is flowing towards the East and is «mined» for the production of ash trays to be sold, as souvenirs, to tourists. |
 22h00; 50mm. All afternoon and until now the SEC hornito drains towards the East. |  22h00; 135mm. Close-up of the grotta-like opening of the hornito. |  22h00; 135mm. Details of the lava flowing towards the East. |  22h15; 135mm. Two parts of the lava flow re-join soon after leaving the hornito. |
 22h00; 135mm. Close-up of the spattering activity from an opening on the western side of the hornito. |  22h00; 50mm. Spattering from an opening on the western side of the hornito. White dots are stars! |  22h30: Suddenly the hornito breaks open on its western side, and from now on all lava drains this way. Spattering is moderate at first, but intensifies as time goes by. |  22h40: Spectacular spattering from the SEC hornito. Very loud degassing takes place at the glowing hole on the left. |
