Briefly after
sunrise these photographs shows a little the size of this lava lake which is
principle a collapsed tube. Starting from the tube on the right this lava lake
was seething up enormously in the morning hours. Up to three meters large lava
shreds ascended on eye level (down photos). The heat development was so
enormous that the observations were not longer possible. The right tube was
filled completely with lava.

If you use the crater rim
as heat shield you had the possibility to evade the enormous temperatures .
Short apperance at the edge permitted detailled photos, thereby numerous
larger shreds did nearly hit us seriously. I like that best to have the
glowing “Peles Tears” in the neck collar or preferentially in the shirt bag
whereby the glowing ejecta can stay a little while, until it finally reaches
the soil by using the burning through method. By the way after this volcano
trip all the clothes changed into rubbish and didn't reached the European
mainland.

The lava
tunnel in a calmer phase. Over night the activities changed in their
violence. “Drop stones” on the left side are actually glass fiber-similar
formations. The so called “Peles hair” appears mostly in ejections and around
the cones. If you have a nearer view at the cone surface you can discover a
lot of spider web similar filaments which are covering partly the cone. See
more in the chapter, 'Peles tears & hairs'.

Ejections over
the edge had been not a rarity. In the middle picture smaller explosions at
the “sucking tunnel” can be seen. To get good long exposures was very
difficult, because the back luminosity of the pond was very high.

Entrance of the 'sucking
tunnel', and a torred lava layer.
The
lava lake level five meter below the edge was always in motion, i.e. with a
strong activity the current was moving from right to left by tearing the lava
crust constantly up and disappeared again in the left tube. The torn crust
plates were aspirated formally like a vacuum cleaner. If the lake came into a
calmer phase the currency was even in the opposite direction.

After some
experiments we are asserting that the silver-shining lava crust is reaching a
very large stability by floating high elastically on the liquid lava. Throwing
heavier rocks on the crust the reaction was at zero. While the heat radiation
at the edge was enormous, the isolating layer in the center shielded the heat
nearly completely. By throwing plastic bottles etc. on the crust of the the
sea, only a little stewing effect begans until the whole rubbish disappeared
in the 'sucking tunnel'. Notable that some centimeters under the the crust you
have temperatures up to 1100 C°.

Note:
The crater rim can collapse without preliminary warning. Sudden activities, or
up to meter large lava shreds can hurt you lethal.
