Lava Flows and Rockfalls in Sciara del Fuoco continue
In March 2003 Roberto Carniel and Marco Fulle returned on Stromboli to maintain our seismic station. They took advantage of two days of warm spring weather to observe current effusive activity in Sciara del Fuoco. All times are local (GMT + 1hr). As usual, data on the lens focal lengths help to understand scales.
26 March 2003, 17h. f=16mm (fish-eye lens) from 400m.a.s.l. Among many new scientific instruments, Roby records rockfalls in Sciara del Fuoco. Dark lava fields from the current eruption in the foreground.
26 March, 17h. f=135mm from 400m.a.s.l. Volcanologists on Bastimento dike (left) observe the smoking dike (right) which previously was active within the summit craters. It is now visible due to a collapse of the NE crater's rim.
27 March, 17h. f=135mm from 273m.a.s.l. During huge rockfalls meter sized boulders fall into an otherwise perfectly calm sea below Sciara del Fuoco. Note the perfectly circular waves generated by each impact.
27 March, 18h. f=300mm from 273m.a.s.l. The velocity of the boulders (up to 3 m in size) is so great that some crash into the water more than 100m from the shoreline.
26 March, 18h. f=300mm from 400m.a.s.l. An active lava front in Sciara del Fuoco releases red lava blocks which then tumble down the steep slopes. Bastimento dike in the foreground.
26 March, 18h. f=28mm from 400m.a.s.l. Two active lava flows release incandescent lava blocks rolling down Sciara del Fuoco. Rockfalls continue in the background.
26 March, 19h. f=28mm from 400m.a.s.l. While lava blocks in the background almost reach the sea, those in the foreground only approach Bastimento. Lepus constellation (The Hare) in the sky.
27 March, 19h. f=16mm (fish-eye lens) from 273m.a.s.l. Eruption Dream. In the sky, from left to right: Sirius, Orion, Taurus (the Bull) with Saturn, Pleiades in a brilliant zodiacal light and a fireball in Andromeda.
