Thrown out lava rocks can injure you seriously, or may kill you!

I made this terrible experience by myself, while descending the crater after the observation. 70m under the rim when I thought I am safe now I turned  back to be sure what is happening. Then I saw a very big bomb (half meter) rising high over the black crater horizon. At first I thought it will fall back in the Bocca Nuova, but then I realized that the thing has a flight trajectory coming straight toward to my standing position. The most difficulty was, that I even couldn't made out up to the last second, if this glowing rock will strike me or not. I was lucky because this bullet passed me in a distance of  five meter. Meanwhile a second bomb beated the rim and was rolling also in my direction. So I had to jump away. Now you see it is very hazardous near the active craters. Please do not ascend  the summit !!

This photo above is showing the left vent which is laying in the northern part of the Bocca Nuova. The most significant sign on this 'one second' exposed Image is, that the out thrown lava left straight radial lines on the Celluloid. This means that this explosion had been so strong that the material of liquid / plastic consistence was shoot very fast and high (200m- 300m) in the atmosphere. Boris Behncke who observed the Bocca Nuova together with two students did guess that on the flat bottom of the crater one tube is centred nearly in the middle. In the late afternoon Wolfgang Müller (down left) tried to get nearer to the crater, but he had no chance to get a view inside, because of  the dangerous explosions.

B.Behncke (on the right)  also mentioned that is very dangerous to stay in the total darkness on the rim, because if any lava plug is exploding you won't see the sometimes not lightning material coming through the night. He had this unpleasant happening three days before. Observing the up to one meter big magma shreds flying in a low altitude over the edge of the crater let us conclude that the pipe on the bottom must be filled plenty with magma.
