Description
The main objective of the project was to establish the basis for further activities directed to seismic risk reduction in the Caucasus region. The main tasks was:
Task 1. Database development.
Develop a consistent, uniform and unified regional seismic and seismotectonic database adhering to strict quality control standards, and made available via an intranet site to all participants and collaborators. This database contain numerous data types including: seismic (historical and instrumental earthquake catalogues, waveform data), geologic and tectonic, geophysical, geodetic, buildings and critical facilities, infrastructure and demography data.
Task 2. Seismic hazard assessment.
Accomplish a regional probabilistic seismic hazard assessment, incorporating all random and known uncertainties, and seismic hazard assessment analysis based upon selected modern, state-of-the-art approaches .Develop regional source zone models as well as regional ground motion attenuation models, including uncertainty. Compile regional seismic hazard maps and used as inputs for the probabilistic loss estimation and risk assessments.
Task 3. Tectonic studies.
Identify active faults, determine their parameters (fault geometry and kinematics, including displacement amplitudes and rates where available etc.). Identify seismogenic zones in the region based on the obtained data on active faulting, as well as historical and prehistorical strong earthquakes and geodetic information on present-day rates of strain accumulation. Develop a model of regional tectonics. The results will be used for seismic hazard mapping and for further scientific studies as well.
Task 4. Seismic risk assessment and training
Apply new modern approaches to probabilistic risk assessment to assessing risk and loss estimation for a selected subset of critical facilities and lifelines. Conduct training workshops and training materials for policy makers, members of the media, and select members of the public.
