Already with the arrival in
St.Vincenzo the
eruption noises
were
strong
hereable.
With the past visits I could not ever
hear a clear window rattling
after a crater explosion in the closer periphery of my pension
which was placed in
the
center of the village
approx. two kilometers away from the active craters. Somehow
it sounded much promising
:-). As turned out
later, the second east
crater which did not saved
with its lava projectiles
was decisive
for this event,
and threw out
voluminös lava over
the east burr
concerning to the altitude.
That means, from
the village center the upper glow
of the
fountains
could be observed in the first night half. Also a new fact
Already at the heli landing
place
at the northwest side (Pizzeria)
of the island
more or less
passable photographs
were taken.
With
the visitors positioned
in the fore ground
on the Quota
400
the photo gives an
impressive
comparison.
But keep in mind,
the
crater terrace lies approx.
one
kilometer from the Q400 more far away.

it started again violently
in
a
ten-minutes pulse
Some things
probably never changes
on
this world. Above all,
the inside of this volcano seems to be fixed
up to
eternity.
In
February 2007
(Martin was at that time
in situ) the
crater terrace was blown out and
deformed so strongly,
that
it was
hard to
realize this
at all.
Meanwhile an impressive cinder cone with double exit ports
developed itself on the eastern side.
By
all
means the
eruption character of each individual vent did not change. The
comparison I would like to draw
out
even into the year
1995, to our first visit. At that time the west crater (right)
was just high-mass
spraying, as in
contrast to the
east craters
thundering
(left).
Between them smaller openings formed
again,
whereby the withdrawing hydrogen ignited
itself
with blue
flames
from the surface
accompanied with an amazing fizzling sound.

about 30
meters high cinder cone with double ejection device.

life

A
centrically
formed
five
meter high cone
has
developed itself,
but presented only
a
little activity
during my visit
.
Side view of the east crater. Up to two meters
large
lava shreds
were ejected
far
out.
During the sunrise again and again fascinatingly: The color
change of the volcanic landscape
Due to
the early sunlight it was possible to photograph more exact
details.
Mt.
Etna seen from Milo
The
generally
bad weather situation in Sicily
permitted
only telephotos of the lava streams
in the Val del Bove.
Because the
lava flows
were situated
close
to
the Pizzi Deneri
actually a
mounting was
planned. However,
during my staytime at
the Sapienza
an ugly
snowstorm
let
my
breakfast coffee
got frozen,
therefore
I decided
not to start from the
northwestern situated Piano
Provenziana.
Southern Abruzzi
Due to the
announced bad weather for the next days, I decided to change
place to the Gargano and the southern Abruzzi, whereby I was
routed during my east-west crossing through the municipal areas
of the city of L'Aquila
By the
different buildup structure more or less destructed buildings.
The eastern suburbs and the historic city of L'Aquila were
damaged apparently hard.
Here
the drawback of the continental drift caused by an earthquake of
the strength of 6.2 on the Richter scale became visibly.
The
untiring assignment of the civil forces brought fast help to the
17.000 homeless people.
Directly coherently
with
the
plate tectonics,
the
Sicilian volcanism
causes
by its often
fascinating fiery appearances
not always
agony
to
humans.
Initiator for this volcanism are the moving procedures of
the southern Mediterranean tectonics.
Here
the
African plate
disappears
by
subduction
diving
under the Thyrrenian
plate
(Eurasian plate).
Due
to the pivoting
of the whole
African plate in northeast direction toward the
Eurasian
continental plate,
the
initiator for earthquakes in South and Middle Italy is a
resulting west-east
movement
which takes place
in the center of the Mediterranean area,
and produces
beside the pressure on the European Alps
also the pressure on the Abruzzi
ridge.
The
main
points of
compression and
relaxation in the rock depths,
has
been situated on the
6th
of
April 2009 around 3.00
o'clock
nearly under the city
of
L'Aquila and caused already in the past devastating
earthquakes and
only
destruction.
The
condition behavior of different building types as well as
possible deformations
in land forms
and roads
awaked my main
interests.
However
ground shifting
or
fissures in the
roads could not be noticed.
