WITHDRAWN Seismic Waves Attenuation in Georgia
Description:
WITHDRAWN Georgia is situated in the Caucasus. It is one of the most seismically active regions in the Alpine-Himalayan collision belt. The analysis of the data of historical and instrumental periods shows that this is the region of moderate seismicity. The strong earthquakes with magnitude up to 7 and macroseismic intensity 9 (MSK scale) occurred here. The recurrence period of such an event is of order 10^ 3 -10^4 years.
My Phd study project is very important and valuable as it will adopt ground motion attenuation models for different parameters PGA, peak PGV and SA. These models are one of the most important stages in seismic hazard assessment, which in turn is the most important prerequisite for seismically resistant constructions and engineering projects.
Recently, there has been an increase in construction and various types of engineering projects in Georgia, and therefore, in view of the implementation of projects in accordance with European and American standards, it is necessary to build full-fledged seismic hazard maps, an important part of which is the use of correct models of ground motion attenuation directly evaluated for the region from which the maps are developed.
This study will be uniquely unique because the latest seismic data will be used together with the data of the 90s, which have accumulated in the last ten years by NSMC and its funding by the Department of Energy, United States of America.
At the same time 12 newest seismic station data will be used in the study, which will make the study unique because for the first time in the Caucasus region Posthole seismic station has been installed in Georgia (12 in total), which has ability to record seismic waves over a wide frequency range (120 seconds to 150Hz).
We will use data from the network of strong motion accelerographs in the period of 90s installed in Georgia and around this territory with the help of Swiss Seismic Service and other organizations. The use of this data is very important for those considering the fact that it is recorded in Georgia by the mentioned stations Significant earthquakes of the instrumental period.
