The record of collision of the Earth with extraterrestrial bodies is far from complete because huge areas have not yet been properly surveyed. Search for the evidence of impact is not an easy task, however, because many impact structures have been erased by geological processes [e.g., Grieve, 1997] . As a result, only a few impact structures are known so far in Northeast and Central Asia (Figure 1) [Grieve, 1997semi; Earth Impact Database, 2002].
