#accaddeoggi 30 giugno 1908: evento di Tunguska

Il mistero siberiano

Nel pieno della Siberia, alle 7.14 del mattino del 30 giugno 1908, si verificò un’esplosione naturale che rase al suolo milioni di alberi su una superficie di 2150 km2.

I testimoni più prossimi, a 65 km di distanza, affermarono di aver visto il cielo dividersi, un grande fuoco sopra la foresta e poco dopo un enorme boato e spostamento d’aria. Il rumore fu sentito fino a mille chilometri e sulla transiberiana, distante 600 km, un convoglio venne rovesciato. Perfino a Londra, dove era mezzanotte, il cielo si illuminò.

Non è ancora chiaro oggi cosa sia avvenuto, ma l’ipotesi più credibile è quella dello schianto di un meteoroide o di una cometa, provato, secondo alcuni ricercatori, dal ritrovamento di rilevanti tracce di nichel e iridio nell'area interessata dall'evento.
