What you speak of there is akin to a BLEVE. BUT that would only be the case if the tank stored methane. The tank in a stockyard would be designed to vent gas, not build up high pressure.
Full disclosure, years ago I was a Georgia certified firefighter. Trust me on this. Not trying to bust you, just know that what you wrote there is unlikely. Truly.
How about this. There was a big Boom! Documented.
