'''Earthquake engineering structures''' are those engineered to withstand [[earthquake]]s.[[File:Chichen Itza 3.jpg|thumb|left|Earthquake-proof pyramid [[El Castillo, Chichen Itza]]]]

The main objectives of earthquake engineering are to understand the interaction of [[structure]]s with the shaking ground, foresee the consequences of possible earthquakes, and design and construct the structures to [[seismic performance|perform]] during an earthquake.

Earthquake-proof structures are not necessarily extremely strong like the El Castillo pyramid at Chichen Itza shown above.

One important tool of [[earthquake engineering]] is [[base isolation]], which allows the base of a structure to move freely with the ground.
