Cat,
I don't know much about building for seismic standards, but how a building withstands an earthquake is also related to whether it's built on bedrock versus soil. The physics has to do with the propagation of the wave through different media, but soil tends to move around in waves during earthquakes and bedrock just jolts. The difference is so obvious when you're in a building! A house built on bedrock will get shocked, but not roll around unless the earthquake is REALLY big.
Stay away from the big cracks in the ground
