• Seismic hazard — refers to the study of expected earthquake ground motions at the earth s surface, and its likely effects on existing natural conditions and man made structures for public safety considerations; the results of such studies are published as seismic …   Wikipedia

• Seismic retrofit — Seismic retrofitting is the modification of existing structures to make them more resistant to seismic activity, ground motion, or soil failure due to earthquakes. Other retrofit techniques are applicable to areas subject to tropical cyclones,… …   Wikipedia

• Seismic wave — Seismic waves are waves that travel through the Earth, most often as the result of a tectonic earthquake, sometimes from an explosion. Seismic waves are also continually excited by the pounding of ocean waves and the wind. Seismic waves are… …   Wikipedia

• Seismic risk — uses the results of a seismic hazard analysis, and includes both consequence and probability. A building located in a region of high seismic hazard is at lower risk if it is built to sound seismic engineering principles. On the other hand, a… …   Wikipedia
