3.-11. March 2007: the Lava Delta grows
Due to the high effusion rate of Stromboli's 2007 eruption, a considerable lava delta was produced at the base of Sciara del Fuoco, just below Filo del Fuoco. In this page we show its expansion during the course of one week. All times are local (GMT + 1hr). Focal length of the lenses used on a digicam is given (to be multiplied by 1.5 to obtain the equivalent focal length on 24x36 film).
3 March, 17h, f=16mm. Very close to the acidic plume of sea-water steam.
3 March, 18h, f=16mm. Each of the two lava flows feeding the delta has a sea entry.
5 March, 14h, f=135mm. Thick steam rises from the contact between lava and sea.
5 March, 14h, f=135mm. A seagull surveying an unusually «hot» environment.
6 March, 18h, f=16mm. Tourist fascinated by magnificent scenery of fire and sea. Venus in the sky.
6 March, 18h, f=16mm. The flow in the foreground is now feeding the delta section closest to us.
7 March, 18h, f=50mm. The lava flow in the foreground has reached the sea: note the thick steam plume.
10 March, 6h, f=16mm. After extending the foreground half of the delta by 20m, the lava flow has now stopped.
