Central Asia is a region of numerous natural and manmade hazards, and ensuing disasters. Historically the most catastrophic losses in the region have been due to strong earthquakes.
The purpose of this project is the establishment of an active seismic information network in Central Asia as the basis for further investigations toward the assessment of seismic hazard, and seismic risk reduction on the territory of Central Asia (Kazakhstan, Kyrgyzstan and Tajikistan). The main tasks of this project are:
1. Creation of a unified, shared, distributed, and common database
2. Characterization of faults and tectonic structures
3. Seismic and landslide hazard assessment
4. Selection of sites for new regional seismic stations
5. Seismic risk assessment for the region and advise to the regional governments on actions and solutions for seismic risk reduction.
Implementation of this project will support the creation of a shared, distributed, regional database with quality control, which will include seismological, geological, geophysical, geotechnical and other data as well as data on critical facilities that could have significant impact in the region if damaged. During the implementation of the project existing scientific data will be collected and newly interpreted for input in the database. Based upon the newly created database a range of regional seismic hazard models will be formulated and seismic risk will be assessed for selected structures/facilities and for secondary hazards such as mountain slopes. New and modern methodologies will be applied and characteristic ground motion attenuation models will be developed.
Tectonic studies will be conducted in order to develop a regional seismotectonic and geodynamic model, as well as the identification of possible alternative tectonic models. Active tectonic structures will be traced and adjusted in transborder regions
Special attention will be paid to regional calibration aimed toward site selection for installation of an improved regional seismic network.
New and modern approaches to seismic risk assessment will be applied to assessing loss estimation for selected structures/facilities in the region. Training workshops and pilot training for policy makers and members of the media will be conducted. Finally the experts will develop a series of recommendations for actions that can be taken by the regional governments, including the development of legislation, insurance, and building codes, in order to better protect the population.
Scientific and practical results obtained under the implementation of the project will be transferred, in a usable format as recommendations to appropriate state and private institutions, organizations and companies interested or responsible for managing and mitigating the natural hazards.
