South East Crater and moonrise over the Ionian Sea; 6 Oct. 1998 (JA). The crater produced a wonderful show this evening and the previous one. | South East Crater 5 Oct. 1998: Powerful strombolian eruptions occurred every few seconds, launching bombs up to at least 300 m! (JA) | South East Crater 5 Oct. 1998: The SE side of the old central crater is an ideal observation point for these observers (JA). | South East Crater 6 Oct. 1998: Note how lava blocks are deflected towards the left by a very strong westerly wind; cloud deck at 2000 m (JA). |
South East Crater 5. Oct. 1998 being monitored by Marco Fulle. Fortunately the very strong wind is from the back, allowing us to shield our cameras (JA). | South East Crater 5. Oct. / 6. Oct.: Note the rapid change of shape of the crater rim and the fracturing and slumping on the right! (JA): And here is a SEC smoke ring (MF). | South East Crater 5. Oct. 1998, telephoto lens: Ejected lava clots are up to several meters in diameter and are bright red even in full daylight (JA). | Boris Behncke studying his beloved South East Crater 5. Oct. 1998 (JA). A lot of information on Etna can be found on his great Website. |
Exceptionally clear air allows us to observe the Eolian Islands in great detail even at this distance: Salina (left), Lipari and Vulcano (right; MF). | Lava flow from 22./23. July 1998 eruption. It did not start at a vent but was produced by masses of fallen scoria. Yellow markers indicate the part of North East Crater which was eroded by this flow; 5. Oct. 1998 (JA). | The eroded flank of North East Crater is directly above Jürg's head. He poses on recent sulphur deposits on the rim of Voragine 5. Oct. 1998; (MF). | Recent sulphur deposits and strong fumaroles on Voragine north west rim (JA). Here we met a group of Hungarian volcanologists. |
Bocca Nuova 16. Oct. 1998 from S rim. Simultaneous lava jet and ash ejection from two vents in the NW part of the crater (MF). | Bocca Nuova 16. Oct. 1998 from S rim. Strombolian activity at the NW vents (MF). | Bocca Nuova 5. Oct. 1998 from E rim. Strombolian activity at the NW vents (JA). | Marco Fulle at Bocca Nuova on 5. Oct. 1998. Jupiter top center (JA). |
Bocca Nuova, SE vent eruption 5. Oct. 1998. Smoke blown away from the crater edge by strong W wind is illuminated by the full moon (JA). | Mild strombolian activity in South East Crater 16. Oct. 1998 as seen from Torre del Filosofo; background: stars circling the north celestial pole (MF). | Ash deposits from the 22./23. July eruption on Bocca Nuova rim have been sculptured by powerful winds. | Winds speeds greater than 100 km/h made work near South East Crater something of a survival exercise; 6. Oct 1998 (MF, JA in picture :-). |
