First of all, thanks to everyone for your nice contributions: i appreciate them very much.
THANK YOU.
Regarding the possible relations between Dalnegorsk and Tunguska incidents:
some observations results were considered somehow related to the Tunguska incident: but a very important point is that basically, many of the element
of the periodic table were found in Dalnegorsk: the parallel with the Tunguska, by this view, is getting very weak with the new analyses that were/are
still being performed both on the Tunguska area and on Dalnegorsk samples.
Dvuzhilny himself has, more recently, if not dismissed, omitted to mention the possible relations between the two events; another extremely important
point is the difference in the dynamic of the events: this one was a relatively "soft" crash, the Tunguska's energy of the blast range event was
most likely 10–15 megatons: so they generated two extremely different scenarios: the first one was an almost intact crash site, in which were found
all the samples, the second one, on the contrary, in according to the most recent findings, would have had the core of the body of impact likely
located here:
Lake Cheko, in the Siberian region of Tunguska: located 5 miles northwest of the epicenter of destruction.
Coutesy: University of Bologna
notice that the epicenter (
see it in Google Maps ) and the core of the body of impact would be located in two
different point: so, basically, what was done in Dalnegorsk three days after the crash (a direct analysis on the body of impact, or its remains),
could be done in the Tunguska now, hundreds years after the event, because only now (if the studies are correct) will be possible to work on a
complete puzzle.
At that point some comparisons could be really made: anyway, two very different incidents of this type may create, at least apparently, very similar
results.
My take, about this specific point, is that after the first analyses showing the presence of elements also found in the Tunguska area, they mentioned
them as a "possible point of relation" while the two events had two very different origins: of course i could be wrong, this is just my
interpretation of what i see as evidences, witnesses, results of analyses and Dvuzhilny's himself statements: perhaps he did mentioned it again, even
recently, and i've simply missed it
.
A very good (and updated) article on the Tunguska event by Luca Gasperini, Enrico Bonatti and Giuseppe Longo can be found here: The
Tunguska Mystery--100 Years Later
I urge it to everyone interested in the case: it's updated and made by the most people presently entitled to talk about the Tunguska's event.
Luca Gasperini, Enrico Bonatti and Giuseppe Longo have studied the Tunguska mystery for many years. Gasperini is a research scientist at the
Institute of Marine Science in Bologna, Italy. Bonatti is professor of geodynamics at the University of Rome ?La Sapienza? and special scientist at
Columbia University?s Lamont-Doherty Earth Observatory.
Longo is professor of physics at the University of Bologna

Thank you again
