Project summary

The territory of the Central Asian countries, Kazakhstan, Kyrgyzstan, Tajikistan and Uzbekistan, is characterized by a high level of seismic activity. Strong and catastrophic earthquakes have occurred, are occurring and will occur in this region. Therefore, seismic monitoring has been and remains one of the most actual problem in the region, having both scientific and applied significance, as the correct initial data are the basis for the formation of seismic bulletins and the catalogues of earthquakes, in which all seismic events registered by seismic stations in the region are indicated in chronological order, as well as basic information about them - the time of origin, geographical coordinates of the epicenter, the depth of the source and the energy estimation (different types of magnitudes, energy class). This information is used in all subsequent scientific studies related to seismic hazard assessment and earthquake prediction problems, fundamental investigations on geodynamics, Earth structure, in applied problems for seismic zoning map creations and new building codes and rules developing.

It is known that there are no state borders for earthquakes, and only close cooperation of seismological organizations in the region with their archives of seismic bulletins and seismograms will help to fill the gaps in the earthquake catalogs and determine the parameters of earthquakes that occurred on the territory with more high accuracy. This is a very actual and essential problem, so far as namely correct (unified) catalogue of earthquakes is the basis for investigation of different scientific problems, such as seismic hazard assessment, earthquake prediction and so on. Moreover, last 20 years each country in Central Asia provides its own assessment of seismic hazard for the country based on different methodologies and approaches. As a result, we have different hazard assessments for the same geological structures, especially in the frontier areas. In addition, many countries use old methodologies and approaches for creation the seismic hazard maps, which are the part of building codes for construction in seismically active areas. As a result, there are problems with the planning of appropriate preventive measures intended for human lives saving and economic losses reducing during catastrophic earthquakes. This project will be intended for solution of this actual problem
