I've heard explosions similarly far away (although it was at the coast and in an unusually quiet place). Explosions in the air travel really far. And every time I heard explosions so far I looked at the news/social media.

In one of these incidents the news article seemed like it might be a coverup to me so I looked up user forums in case someone leaked the real information.

Do you remember what explosion it was that you heard 80km away? Because I seriously doubt any of the weaponry Russia has dropped so far can be heard anywhere close to that far.

Not OP, but I remember reports of https://en.wikipedia.org/wiki/Buncefield_fire explosion which wikipedia claims "Because of an inversion layer, the explosions were heard up to 125 miles (200 km) away".

In my original post I was referring to an explosion _inside_ Belgorod: https://www.reuters.com/world/ukraine-strikes-fuel-depot-rus... which may or may not be directly linked to the war; Ukraine has denied responsibility.
