Ground shaking induced by destructive earthquakes can be highly variable, even over small areas, as it has been shown at the local scale to be largely dependent on near-surface geology heterogeneities. Unfavorable site conditions—not uncommon in high-risk urban environments—threaten to increase ground motion amplitude and duration.
In order to properly account for the effect of local seismic response, accurate modelling of heterogeneous upper-crustal and soil behavior is necessary. However, this requires detailed knowledge of the subsurface geology, often difficult or too expensive to obtain over numerous sites. Previously, seismic hazard analyses relied on the spatial ergodicity assumption to collect sufficient data for reliable predictions. However, this resulted in high uncertainties.
Nowadays, we can reduce the high epistemic uncertainty by performing site-specific seismic hazard analysis thanks to the introduction of novel site-characterisation geophysical techniques and sophisticated instrumentation, data availability from dense seismic networks, and recent improvements in ground-motion modelling. Nevertheless, this shift introduces numerous issues and new challenges to the scientific community.
For this Special Issue in Geosciences, we encourage original contributions from a wide range of topics related to site-response analysis, ground motion modelling and seismic hazard, with a particular focus on the reduction of uncertainties. This includes, but is not limited to, the following areas:
- Seismic site characterization using state-of-the-art geophysical techniques, e.g., controlled source vs. ambient vibration;
- Advances in numerical/analytical modelling of low-velocity sites, including surface/subsurface topography;
- Non-linear soil response;
- Site attenuation;
- Data mining and harmonization of soil properties;
- Development of new site-specific empirical ground motion prediction models;
- Definition of innovative and improvement of existing site proxies;
- Site-specific seismic hazard studies (deterministic/probabilistic);
We are looking forward to receiving novel contributions to these research fields in this Special Issue.
