    This pressure compresses the material in the subsurface more and more the further down you go. Building a horizontal passageway, or a tunnel, through this material, interrupts the flow of these compressive forces.

This “camouflet” caused the enemy tunnel to collapse. The Israelis have invented new munitions that are much more powerful than dynamite.
