The 1993 Jerzmanowice event in Poland and the 1908 Tunguska event

Andrei Ol'khovatov 

This paper is a continuation of a series of works, devoted to various
aspects of the 1908 Tunguska event. In this paper its author would like to draw attention to the phenomenon that is sometimes called the Polish Tunguska in the Polish media, although it would probably be more correct to call it mini-Tunguska. In
the evening of January 14, 1993, the village Jerzmanowice (about 20 km NW from the city of Krakow (Cracow) in Poland) was shaken by a powerful explosion. Some seconds later, stones of various sizes fell on the part of the village. Soon it was
discovered that the source of the falling stones was a limestone crag. Fuses of electrical equipment in 30 houses also burned out. Some glowing flying objects in the sky were reported.
At first it was proposed a meteorite fall, but later it was discovered that the answer is not so simple. A review and some analysis of the event is presented in this
paper, as well as some comparison with the 1908 Tunguska event.
