As reviewed over, concrete is extremely solid in compression, but weak in stress. Much larger earthquakes can make pretty large shear loads on structures. These shear hundreds issue the construction to both of those tensile and compressional hundreds. Concrete buildings without reinforcement, like other unreinforced masonry buildings, can fall short during significant earthquake shaking.
