In the earthquake-prone central Andes Mountains, there archaeological sites with monumental adobe and stone block structures standing that were built by ancient people hundreds and even thousands of years ago. Clearly, the ancient builders planned to have their important structures last–-and they had the knowledge to build appropriately for their environment. Buildings that promise to last a long time are also being constructed today.

Lots of information is packed into those words. Importantly, it provides evidence of our limited knowledge about the hazards presented by earthquakes.
