episode of vigorous lava fountaining from the Southeast Crater in
May 1980, photographed by Giuseppe Scarpinati. The crater resumed
its eruptive activity after about seven months of relative quiet,
following its impressive activity during the August 1979 eruptions.
The activity in 1980, however, did not culminate in a flank eruption.
about the same time the SE Crater resumed its activity in the spring
of 1980, very intense eruptive activity occurred within the Voragine,
and the crater was filled with lava to within 25 m of its eastern
rim. This photo, taken by Giuseppe Scarpinati a few months later,
shows the flat floor of the Voragine as seen from the flank of the
adjacent Northeast Crater, and a deep notch eaten into the southern
crater rim by the expanding Bocca Nuova, which lies behind the peak
