Einkenni jarð­skjálfta­svör­unar hraun­laga undir vegum og brúm út frá mæling­um á jarð­óróa

One of the important lessons learned from catastrophic earthquakes (San Francisco,1906;
Mexico City, 1985; and Loma Prieta, 1989) is that the seismic waves can significantly change
over relatively small areas because of variation in localized geological conditions (Seed et al.
1988; Aki 1993). Since the spatial variability of strong ground motions can significantly affect
the response of lifeline and service networks (e.g., electricity transmission networks, power
grids, pipelines, water supply, and sewage systems), local and site-specific characteristics
should be considered as a critical factor in earthquake-resistant design and studies of where
earthquake ground motion may be systematically higher than in other areas.
