Earthquake-resistant or aseismic structures are designed to protect buildings to some or greater extent from earthquakes. While no structure can be entirely impervious to earthquake damage, the goal of earthquake engineering is to erect structures that fare better during seismic activity than their conventional counterparts.
One of the early examples of the earthquake design strategy is the one given by Dr. J.A. Calantariens in 1909. It was proposed that the building can be built on a layer of fine sand, mica or talc that would allow the building to slide in an earthquake, thereby reducing the forces transmitted to building.
Steel structures are considered mostly earthquake resistant but some failures have occurred. A great number of welded steel moment-resisting frame buildings, which looked earthquake-proof, surprisingly experienced brittle behavior and were hazardously damaged in the 1994 Northridge earthquake .

The rigidity of its marble structure combined with soft soil below helps the Leaning Tower of Pisa withstand seismic waves, according to new research funded by Opera della Primaziale Pisana.

Seismic retrofitting is the modification of existing structures to make them more resistant to seismic activity, ground motion, or soil failure due to earthquakes.With better understanding of seismic demand on structures and with recent experiences with large earthquakes near urban centers, the need of seismic retrofitting is well acknowledged.
The Times has obtained a list of soft-story buildings requiring a seismic retrofit in Beverly Hills. 42 buildings in Beverly Hills aren't seismically retrofitted. Is yours at risk in an earthquake?
When a 7.2 magnitude earthquake hit Taiwan's scenic and largely rural east coast county of Hualien on Wednesday, local official Chang Tung-yao knew exactly what to do, having experienced a similar ...
