8 June 2000 update.
The SE Crater erupted again on the afternoon of 8 June. This 62nd
eruptive episode since late January was preceded by minor ash emissions
from the summit vent of the crater at about 1530 h, which gradually
intensified, the activity becoming Strombolian in character. At about
1600 h the activity culminated with spectacular lava fountains and
the generation of a heavily tephra-laden eruption column. The event
was plainly visible in daylight from Catania, in spite of weather
clouds. The tephra plume was driven to NW, an unusual wind direction.
At the beginning of the lava fountaining phase the fall of large bombs
and scoriae on the NE slope of the cone was so intense that small
pyroclastic avalanches were generated. Lava flowed in a narrow stream
over the S lip of the crater, reaching the S base of the cone and
extending SW from there. Lava flows presumably also occurred on the
N side of the cone. The activity continued vigorously until about
1620 h and then rapidly declined, giving way to forceful ash emissions
that continued for another 5 minutes and then became intermittent.
All activity was over by about 1635 h.
6 June 2000 update.
Shortly after the eruptive episode at the SE Crater on the morning
of 5 June a light rain of ash fell on Catania. This was much lighter
than that of the morning of 1 June, and the size of the falling particles
was smaller. Heavier tephra falls occurred in areas closer to the
volcano on the S and SSW flank, such as Nicolosi. The eruption column
generated by the paroxysm rose at least 3 km above the summit, although
some eyewitnesses estimated much greater heights. Bombs and large
scoria clasts fell abundantly to the SW of the SE Crater, and also
around the Torre del Filosofo building. Charles Rivière observed
after the eruption that bombs had fallen quite beyond the building
as well.
5 June 2000 update.
Three days and 9 hours after the previous paroxysm, the SE Crater
produced its 61st eruptive episode since 26 January. Like its predecessors,
this new paroxysm was preceded since the early morning hours of 6
June by the emission of lava from the eruptive fracture on the N flank
of the SE Crater cone. Between 0600 and 0650 h the effusion rate increased
exponentially, and a dense plume of yellowish-white gas rose from
the vents. At 0650, gas was emitted also from the summit vent of the
crater, and at about 0655 the emissions became mixed with ash. A few
minutes before 0700, the activity entered into the paroxysmal phase,
with lava fountains, and the generation of a dense tephra column.
While much of the coarse grained fallout occurred to the SW of the
cone (due to a northeasterly wind at the elevation of Etna's summit),
the higher, more dilute portion of the plume was slowly driven towards
NE, and possibly some tephra fall occurred in that sector, most probably
in the area of the town of Fiumefreddo. The plume, which was distinctly
visible on satellite imagery, then drifted towards the southern tip
of Calabria. However, some tephra may have been carried SW by the
wind at about 3300 m elevation, and lapilli may have fallen in the
area between Adrano and Paternò. Several other web pages covering the recent and ongoing eruptions of the Southeast Crater are now available; these contain photos and movie clips of some of the most spectacular moments of that period.

a minor economic input for this site which has become more and more
