Following its
eruption in July-August 2001, Etna took a rest of about ten months, then,
in the summer of 2002, magma reappeared in two of its summit craters.
This had been preceded since early March by ash emissions, first from
the Bocca Nuova and then also from the Northeast Crater. For nearly three
months, the latter of the two showed intermittent Strombolian activity,
and the floor of its central pit rose to 50 m below its rim. At night,
explosions were visible even from great distance. Etna was back on the
stage, but no one would have expected it to erupt in the manner it did
during the night of 26-27 October 2002. But this is not the place to repeat
the chronology of those events, which are described in detail on the 2002-2003
eruption page. Here are the photograps of that eruption, which caused
serious distress to the people living in a large area around the volcano,
and three stressful months for all who were engaged in dealing with the
emergency - the scientists, civil protection, and those whose property
was lost or at risk

First
view of Etna's eruption on 27 October 2002, taken from a sailboat
offshore the island of Vulcano, Aeolian Islands (seen in the foreground),
about 100 km north of Etna. An enormous cloud of ash is rising
thousands of meters into the sky, veiling the volcano. The clear
weather on this day permits to see two volcanoes erupting at the
same time - Stromboli (lower left photograph) and Etna (lower
right photograph) |

This
is the close-up view of the eruption, seen and photographed by
Pippo Scarpinati on 27 October 2002. Left photograph shows lava
fountaining from a vent on the Northeast Rift, which has split
open along a length of about 2 km, and lava from this vent is
rapidly spilling down the steep slope below the vent, heading
directly toward Piano Provenzana and its touristic infrastructures.
At noon on the same day, the fiery flood arrives on the plain,
burning a ski school and then proceeding further across the flat
terrain. Everybody who has remained there until then - mostly
owners and employees of the tourist facilities, local residents,
journalists, and geologists - is forced to leave the place instantly,
because the only access route to Piano Provenzana is in the path
of the lava flow. No one was there to see how Piano Provenzana
vanished from the face of the planet
The last photographs taken of Piano Provenzana that day - along
with the one above - are available on the web pages (in Italian)
of the Etnean volcanological and mountain guides: etnaescursioni.it,
and of the Finocchiaro photo studios of Linguaglossa: Finocchiarofotografi.net
- note that the latter site wrongly gives 24, not 27, October
as the first day of the eruption |
Earthquakes
on Etna's eastern flank, 29 October 2002
|
|
Following
the intense seismicity that accompanied the beginning of the eruption
(mainly on the northeastern flank), earthquakes began to extend
all over the eastern flank of the volcano, and several larger
shocks shook the area between Milo and Santa Venerina on 29 October.
Damage was greatest in the Bongiardo quarter of Santa Venerina,
where several buildings collapsed, but structural damage occurred
in nearly all population centers up to Milo. These two photographs,
taken a few days later by Giuseppe Scarpinati, show destruction
in Santa Venerina. As of August 2003, there is still much destruction
visible in that village |
Two
eruptions-in-one, 31 October 2002
|
This
morning view, taken by Pippo Scarpinati, of the erupting volcano
from Acireale (lying to the southwest of Etna) clearly shows the
two eruption sites on the southern (left) and northeastern (right)
flanks. And in fact, both are producing different types of magma
with different eruptive styles, though the process that triggered
the eruption was very likely the same - the sliding of a huge
portion of the eastern flank of the volcano |
Lipari
to Catania, 30-31 October 2002

Left:
seen from due east, the ash columns rising above Etna are actually
three - one, at left, fed by the strongly explosive south flank
vents, a second, broader one comes from the summit craters (in
certain moments during the first day of the 2002-2003 eruption,
three of the four summit craters produced strong explosive activity),
and the third one at right is produced by the remaining active
Northeast Rift vents. 31 October 2002
Center: the square in front of the train station of Catania is
covered with black ash, like everything around Etna. And the volcano
continues to erupt in the background - this is only the sixth
day of an eruption that will last for three months
Right: buildings in Catania covered with black ash, 31 October
2002. On that day, in the northern-central part of the city, the
thickness of the ash was at least 2 cm when freshly fallen, significantly
more than during the 2001 eruption |
Northeast
Flank, 1 November 2002
|
|
|
On
the morning of 1 November 2002, the eruption, is continuing strongly
on the southern flank, producing the dense ash column visible
at left in both the left and center photographs (the second, more
dilute plume visible in those images is rising from the summit
craters). However, on the Northeast Rift, the show is largely
over. The upper vents of the eruptive fissure on the northeastern
flank are releasing only wisps of gas (visible at right in center
image), and the lowermost vents, lying immediately above the devastated
Piano Provenzana, show weak explosive activity (right photograph).
Lava continues to advance slowly across the pine forest known
as "Ragabo". The photographs were taken from the Monti
Sartorius area, about 3 km from Piano Provenzana |
'a
muntagna scassau, 1 November 2002

|
The
effects of the dramatic events of the first days of the eruption
are seen here in an eerie atmosphere on the late afternoon of
1 November 2002. The air is filled with ash, there's ash everywhere,
also on the "Mareneve" road, partially hiding the spectacular
cracks related to the enormous flank slip along the Pernicana
Fault. The larger of the cracks, however, are well evident (left
photograph). And above all this, the volcano is venting more and
more ash into the atmosphere, as a pale sun is setting behind
its western crest (right) |
