- Development of high-resolution tomographic models for the target areas using a high-quality pool of local earthquakes' P and S travel times, combined with the near-surface shallow structures (basins and topography) derived from other geological and geophysical investigations. Constructing crustal velocity models and mesh files that can be utilized for 3D ground motion simulations for historical and future earthquake scenarios in the central Apennines.
- Collecting a suitable database of documented waveforms will be primarily established on the European Strong Motion Database and ITACA. The accelerometric dataset will be merged with velocimetric data from denser networks whenever strong motion data are lacking. Ground motions recordings will also be linked to macroseismic intensity data from DBMI15. Reviewing and processing earthquake recordings from stations on different site conditions (rock and soil) and collecting public metadata into a flat file (magnitude, distance, site conditions, etc.).
- Defining the inputs for finite-fault simulations (Databases for active faulting or Macroseismic Intensity distributions of historical earthquakes).
- Estimating earthquake source-related parameters (such as stress drop, apparent stress) and the related propagation parameters (such as Q(f), kappa). Generating stochastic and hybrid physics-based rupture models.
- Developing non-stationary and non-isotropic empirical ground-motion models can describe the ground motion features during a seismic sequence.
- Generating synthetic seismograms throughout 3D physics-based broadband simulations using consolidated and innovative approaches for earthquake engineering applications.
- Performing tests on GMMs, parameters, and simulations to assess their applicability and validity in seismic hazard assessment.
- Establish a website dedicated to SECURE, disseminating, and exploiting the project's results and activities.
