| Zusammenfassung |
The seismic hazard of the Iberian Peninsula is analysed using a nonparametric
methodology based on statistical kernel functions; the activity rate is
derived from the catalogue data, both its spatial dependence (without a
seismogenic zonation) and its magnitude dependence (without using
Gutenberg–Richter's relationship). The catalogue is that of the Instituto
Geográfico Nacional, supplemented with other catalogues around the
periphery; the quantification of events has been homogenised and spatially or
temporally interrelated events have been suppressed to assume a Poisson
process.
The activity rate is determined by the kernel function, the bandwidth and the
effective periods. The resulting rate is compared with that produced using
Gutenberg–Richter statistics and a zoned approach. Three attenuation
relationships have been employed, one for deep sources and two for shallower
events, depending on whether their magnitude was above or below 5. The
results are presented as seismic hazard maps for different spectral
frequencies and for return periods of 475 and 2475 yr, which allows
constructing uniform hazard spectra. |
