Near-Surface Effects: Advances in Site Response Estimation and Its Applications [Poster]
The effects of shallow geological layers and interfaces (within the upper 1-2 km) on the seismic-induced ground motion recorded at the surface have been the focus of numerous studies over the past few decades. However, while the methods for simulating ground shaking have rapidly evolved, making robust 3D calculations feasible for broadband seismograms, the approaches for determining their input parameters at the necessary level of detail still suffer from a range of limitations and uncertainties. Furthermore, it is today recognized that the ground shaking recorded at the surface is also affected by the energy released back to the ground by building structures that might contribute to locally increase or decrease ground motion.
The aim of this session is to present studies dealing with innovative approaches for the investigation of shallow geological layers and interfaces; site response assessment, in particular, considering the spatial variability of seismic ground motion at small wavelengths and uncertainties in site response models and their inputs; and building/city-soil interaction. Studies dealing with the assessment of the attenuation of wave propagation and those focusing on non-linear behavior by making use of arrays of sensors, both in boreholes and in buildings, are particularly welcome. Studies involving innovative applications of horizontal to vertical spectral ratio (HVSR) methods for investigations of shallow geological interfaces, seismic microzonation studies and site response assessment are also encouraged. Furthermore, case studies dealing with local secondary effects due to earthquake shaking, such as liquefaction and landslides, in non-standard situations are also invited.
