The solution to that is to build it bigger with a wider footprint. Obviously this is an expensive way to build, but if you engineer it right (and throw enough concrete at it) you can create structures with nearly arbitrary shake resistance.

(Think of how hard you'd have to shake the Great Pyramid of Giza to make it collapse. That's not concrete obviously, but it too is under compression almost entirely, except for the corbel and lintel ceilings. The proper arches used in Roman concrete construction show that with the right engineering you can push unreinforced concrete pretty damn far. The Pantheon is probably the most impressive example of it. Compare how well it's withstood earthquakes with the Colosseum.)
