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.
