For conventional facilities, the seismic regulations of each country normally include a seismic hazard map. For especial installations, such as nuclear plants or liquefied natural gas tanks, a site-specific study must be conducted prior to designing the facility.
Principia has analysed the seismic hazard and generated motions for the design and analysis of facilities at more than 50 sites all over the world, using the more recent and reliable methodologies, with non-parametric approaches for establishing the activity rates, and with attenuation laws that reflect the state-of-the-art in each area and for each type of earthquake.
The results are typically expressed in the form of seismic hazard curves and uniform hazard spectra.
