Stromboli photos

19.-20. May 2009: Very Strong Activity

In May 2009, Marco Fulle led a VolcanoDiscovery group to Pizzo with local Magmatrek guide Mario Pruiti. Strong activity at NE crater has formed a steep cone, erupting bubbles of very fluid lava. SW crater erupted tall ash columns with fine lapilli: occasionally ash rings were formed, a very rare phenomen, as that seen at noon of 20 May from Punta dei Corvi. All other photos were taken on 19 May between 7h20pm and 8h20pm from Bastimento, and then at 9pm from Pizzo (GMT + 2hr). The focal length of the used lenses helps to understand the scale (digital reflex camera with 16x24mm sensor).

19.-20. May 2009: Very Strong Activity
A 200m-wide ash ring from SW crater (from Punta dei Corvi, f=10mm).
19.-20. May 2009: Very Strong Activity
Sunset and an eruption from the E vent of the new NE cone (Bastimento, f=10mm).
19.-20. May 2009: Very Strong Activity
Rockfalls trigger small pyroclastic flows from rim of the NE vent (f=20mm).
19.-20. May 2009: Very Strong Activity
Highly fluid lava bubbles burst within the eastern vent of new NE cone (f=200mm).
19.-20. May 2009: Very Strong Activity
Rockfalls and avalanches of hot dust (rolling bombs at lower right, f=80mm).
19.-20. May 2009: Very Strong Activity
Sometimes the explosions at NE cone are very ash-rich (f=200mm).
19.-20. May 2009: Very Strong Activity
A small lava flow from the eastern vent emits bluish gas (f=200mm).
19.-20. May 2009: Very Strong Activity
SW crater erupts huge "ash mushrooms" (left). Low cloud deck at right (f=10mm).
19.-20. May 2009: Very Strong Activity
Strombolian eruption at the western vent, while a lava flow emerges from the E vent (bottom; f=50mm).
19.-20. May 2009: Very Strong Activity
Strombolian eruptions at the western vent also eject very fluid, incadescent lava clots (f=200mm).
19.-20. May 2009: Very Strong Activity
Spectacular burst of hot and fluid lava at the eastern vent of new NE cone (f=50mm).
19.-20. May 2009: Very Strong Activity
Big rockfalls over the unstable lava flow trigger avalanches of very hot material (f=50mm).
19.-20. May 2009: Very Strong Activity
A longer exposure highlights the lava flow and the complex structure of the eruptive bursts (f=50mm).
19.-20. May 2009: Very Strong Activity
After a few seconds, the entire NE flank of the cone gets covered by incadescent pyroclastic material (f=50mm).
19.-20. May 2009: Very Strong Activity
Continuous spattering at central crater, with strong glow from the western vent in NE cone (from Pizzo, f=50mm).
19.-20. May 2009: Very Strong Activity
Lava fountain at the NE cone western vent, and strong red glow from the lava flow at the eastern vent (f=50mm).
