Fascinating stuff--and you kept it simple by using 'speed of sound in a medium' as opposed to 'celerity', a word I've never seen used since my Engineering days.
Thank you - before the war the assumption - at least in Sweden - was the concrete and shallow rock fortifications were useless and in the last 20 years all such fortifications were destroyed with great energy, including rather deeply buried air defense centers or operational command bunkers. But then the resilience of the Ukrainian concrete fortifications showed itself. I guess with a concrete fortification you are screwed but without one you are more screwed!?
WIth your explosions experience you may find the following - unwarlike - investigation of great interest, about the Carolina Bays, oval depressions found in soft soil in various parts of the US, likely formed by secondary ejectae of ice boulders from a meteorite strike on the Canadian glacier near the Great Lakes 12000 years ago, leading to the extinction of the mega fauna in the US and the majority of the Clovis culture.
I think that the last sentence is really horrifying - “Destruction of underground structures can be compared with the destruction of a submarine simply because hardly anyone survives to tell the story.” We need a peace negotiation!
Thank you
Congratulations on the new book. Looks great!

No peace negotiation. There is no one honest to negotiate with in the "west".
Russia must destroy all NAZI s & AngloZionist scum wherever they are.
Then there will be peace.
Sadly, I agree.
Realy nice explantion.
probaly almos no defnace from this treat.
Thank you for this masterpiece on the physics of explosions. I am loving it.
You are welcome!
