Crater 1 from Pizzo, 28.4.96. Vent 1/2 was permanently throwing scoria up to a height of about 50m. They are, however, not visible in this image. The permanent activity was 'modulated': Its intensity varied on a time scale of roughy half an hour. Apart from this, regular eruptions also took place from this vent every few minutes. Crater 1 also erupted from vents 1/3 and 1/4.
