Tunguska Event(June 30,1908) is only one example!!!!Why?I harshly will suggestBlogger for answer
My individual experiments about Tunguska Event are expressing effect of "SEISMIC SHOCK WAVES" created of explosion caused of "Comet or Asteroid Type Impacts"!!!This thesis not only absence of a meteroid remnant at Tunguska Crater Field but also confirming with Chemical Analysis on C14 Isotope and Ir tests!!!! So,I especailly mean that about producing capability a deformation effect of "SEISMIC SHOCK WAVES" realised on explosion phenomena of deformation morphology🙌 You are right!I especially say some geoenvironments realised on similar mechanism of this type events with various impactive type morphologic basin 😐 YES.You can not observe any meteoritic strs for relatively "big impactive basin envs"...But,you must consider relationship to mechanisms expressed on geology history of this condition👍 Thanks..
