Shota Rustaveli National Science Foundation Grant

At Saint Andrew the First-Called Georgian Universitys Faculty of Informatics, Mathematics and Natural Sciences has received the grant of Shota Rustaveli National Science Foundation devoted to earthquakes problem (George Khazaradze, Manana Kachakhidze).

High geodynamic activity of Georgia and adjacent areas of the Caucasus, expressed in both seismic and aseismic deformations, is conditioned by the ongoing tectonic activity. Particularly, by a northward propagation of the Arabian plate towards the Eurasia, with at a current rate of 7 to 10 mm/year.

The post-collisional, sub-horizontal shortening of the Caucasus is estimated at hundreds of kilometers. Such a considerable shortening of the Earth’s crust has been realized in the region through different ways: (1) crustal deformation with wide development of compressional structures; (2) warping and displacement of crustal blocks themselves with their uplifting, subsidence, and underthrusting beneath each other and (3) lateral escaping.

Two devastating earthquakes have occurred in the Caucasus in the past years. The first one was the Spitak earthquake on December 7, 1988 in Armenia at the Georgia-Armenia border (M=6.9). The other large seismic event was the Racha earthquake on April 29, 1991 which was followed by numerous aftershocks, the strongest one occurred on April 29 (M=6.1), May 5 (M=5.4), and June 15 (M=6.2) causing additional damage.

Unfortunately, Georgia like Turkey, Greece and other countries is considered as seismically the active country. For this reason searching of earthquakes problem is vital for our country. The presented pilot project proposes to install experiment stationary station of electromagnetic emissions prior to earthquakes.
