Two of the largest buildings in the world collapsed next to this building. What did the shock waves do to the concrete foundations of Building 7? What was the Richter scale earthquake rating for building 7? The Richter scale really does not apply to very localized shockwaves. That is better understood from the large 10 ton bombs used by the British Damn Busters squadron that used shock waves to destroy U-boat pens. They were designed to penetrate deep in the earth next to the sub-pens to fracture the massive concrete walls of the sub-pens.
