Stromboli, April 2004
' stalactic' light impressions in the western direction
After the volcanic causes from
April 2003 it was necessary to visit the
Stromboli. Surely it was well known by us that
still exist but
the structure of the crater terrace was a mystery. In
addition we noticed in October 2003 from
the Calabrian coast a new summit
form. Did looked at that time
itís not like that! Everything
where it should belong.
Inside the main crater the
may four or
grew steady in
were totaly blown up. There was nothing to see anymore. Now, only one
large crater makes you understand, what enormous forces
at this place one year before.

Ascent from the Fossetta. A notice to the Sciara
del Fuoco. Surprised we saw that every eruption caused a stone avalanche
down the Sciara. We had the impression that the whole slope was in such a
loosen consistence that might be more bigger avalanches
will go down in the future
After we moved three days between zero and 918 meter we had
that we were involved into a dwell phase of the volcano.
What a mess!
the first night:
Clouds and too much
steam in the crater beside
a little activity.
no activity and problems of prohibition on the Quota 400. Possibly it was
not permitted to enter the upper area? Third night:
Hide and seek in the bushes crowned with cave-hiding. The night comes the
guides are going, but finally clear sky.

In the western part the crater rim partly continued to grow in its radius.
Old area formations are however still to be recognized.
The distance of observation was about 350
the ejection height averaged with approximately 100 m. The crater had an
opening of apprx.100

In comparison to October 2002
changes of the crater are shown. Thus the eastern part of the crater wall
was literally blown up. This becomes visible at the left
on the photos.

Shadow of Venus

Did you know
that Venus is the only planet which can produce a
shadow? So far I read it only in books. During we attended to the
terrestrial on goings on 650 meters we noticed in the total darkness that
the bright rocks of the northwest slope
doings did had have a ' shade existence '. After I recognised that our main
planets were positioned at this time under the horizon only Venus
(time during the sunset and moonrise, 2h). With joy I
stated that in an absolutely dark environment, light phenomena are possible
the upper photo you see Venus, the shine of Venus on the sea and the shade
of a cloud which was reflecting up to us.
