Site Characterization of Swiss Strong-Motion Stations: The Benefit of Advanced Processing Algorithms
Autor: Jan Burjánek, Clotaire Michel, Donat Fäh, Paolo Bergamo, Vincent Perron, Francesco Panzera, Manuel Hobiger, Walter Imperatori, Agostiny Marrios Lontsi
Publikováno v: Bulletin of the Seismological Society of America. 111:1713-1739
Since 2009, 91 new strong-motion stations were built for the renewal of the Swiss Strong Motion Network. Another nine stations will be installed until 2022. For each new station, an extensive site characterization study is performed to model the 1D s

Reconstructing a 3D model from geophysical data for local amplification modelling: The study case of the upper Rhone valley, Switzerland
Autor: Francesco Panzera, Jonas Alber, Walter Imperatori, Paolo Bergamo, Donat Fäh
Publikováno v: Soil Dynamics and Earthquake Engineering, 155
The geometry of three-dimensional subsurface structures plays an important role in determining local seismic site effects as in the case of alpine valleys. Detailed knowledge of these structures is fundamental in seismic hazard and risk studies. In t

Joint multizonal transdimensional Bayesian inversion of surface wave dispersion and ellipticity curves for local near-surface imaging
Autor: Francesco Panzera, Walter Imperatori, Donat Fäh, Miroslav Hallo
Publikováno v: Geophysical Journal International, 226 (1)
Physical properties of near-surface soil and rock layers play a fundamental role in the seismic site effects analysis, being an essential element of seismic hazard assessment. Site-specific mechanical properties (i.e. shear- and compressional-wave ve

Hybrid Broadband Seismograms for Seismic Shaking Scenarios: An Application to the Po Plain Sedimentary Basin (Northern Italy)
Autor: Andrea Morelli, Irene Molinari, Julie Baron, Meeke C. van Ede, Walter Imperatori, Edi Kissling
Publikováno v: Pure and Applied Geophysics. 177:2181-2198
The densely populated Po Plain, a very deep sedimentary basin in northern Italy, is prone to heavy shaking during earthquakes. Seismic hazard assessment must account for local variation in wave amplification. Standard ground motion prediction equatio

Combining recordings of earthquake ground-motion and ambient vibration analysis to estimate site response variability in the city of Lucerne, Switzerland
Autor: Donat Fäh, Luis Fabian Bonilla, Vincent Perron, Walter Imperatori, Paulina Janusz, Christoph Knellwolf
Publikováno v: EGUsphere
Estimation of site effects is an essential part of local seismic hazard and risk assessment, especially in densely populated urban areas. The goal of this study is to assess the site response variability in the city of Lucerne (Central Switzerland),

Validation of 3D Velocity Models Using Earthquakes with Shallow Slip: Case Study of the 2014Mw 6.0 South Napa, California, Event
Autor: František Gallovič, Walter Imperatori
Publikováno v: Bulletin of the Seismological Society of America. 107:1019-1026
3D velocity models constitute a key element in strong ground motion modeling, for example, earthquake‐hazard assessment. Their validation is typically based on modeling weak earthquakes with foci limited to depths greater than ∼5 km. However, rup

Effects of three-dimensional crustal structure and smoothing constraint on earthquake slip inversions: Case study of theMw6.3 2009 L'Aquila earthquake
Autor: P. Martin Mai, Walter Imperatori, František Gallovič
Publikováno v: Journal of Geophysical Research: Solid Earth. 120:428-449
Earthquake slip inversions aiming to retrieve kinematic rupture characteristics typically assume 1-D velocity models and a flat Earth surface. However, heterogeneous nature of the crust and presence of rough topography lead to seismic scattering and

Geophysical Journal International, 2016, 27 (1), pp.439-456. ⟨10.1093/gji/ggw289⟩
We introduce the MUSIQUE algorithm and apply it to seismic wavefield recordings in California. The algorithm is designed to analyse seismic signals recorded by arrays of three-component seismic sensors. It is based on the MUSIC and the quaternion-MUS
