Which risk increases when subjecting medieval stone vaulting to explosions?

💡 Explanation

Arch ribs buckle rapidly because the shockwave impacts multiple points non-uniformly, increasing unevenly-distributed stress; therefore, rib buckling presents more often rather than keystone ejection happening in isolation because structural support fails.
