I'm sorry, I am not sure if I can understand you, but I think see where your going. However, if your say Zilla was killed by a tail slam...hate to break it to ya, but Zilla was taken out by Godzilla's atomic breath.
technically yeah, but also remember till the recent movie, most godzilla kaiju NEVER died when they hit a building due the budget effect (added zilla was a basic CGI scan of a toy for final wars) but before he got blasted, he was tailslamed when he tried to jump gojira like how the male muto tried. and the sidney opera house do have points on it shell shaped roof. that why he the closest to the male muto in death, closest but not exact.
