As mentioned higher than, concrete is incredibly powerful in compression, but weak in stress. Larger earthquakes can create extremely substantial shear masses on structures. These shear loads matter the composition to equally tensile and compressional hundreds. Concrete structures without reinforcement, like other unreinforced masonry buildings, can fail for the duration of intense earthquake shaking.
