Deformation of Earths crust to south of Baku can lead to serious quakes and narrowing of Caspian
Baku, Fineko/abc.az. American seismologist predicts an increase in seismic activity of Baku and on the Absheron peninsula.
At the International Seismology Conference taking place in Baku American scientist and seismologist Robert King has informed that in Baku and Absheron peninsula it is expected an increase in seismic activity as a result of compression fracture between the Minor and the Greater Caucasus.
"Our research showed that the Arabian and Eurasian lithospheric plate is characterized by high strength, and as a result they do not deform internally, and tremors are the result of oceanic activity, located between these territories. In the entire Caucasus a fault is observed, in the south and the north there is some movement and deformation in the lowlands between the Minor and the Greater Caucasus. In the Baku seismic zone the speed of fault is 12 mm a year over 100 km. At that, to the south of Baku it is observed fracture and displacement of the Earths crust in the direction of the Caspian Sea, where compression takes place that will lead to a narrowing of the Caspian Sea. At the same time, we find it difficult to predict the results of all the occurring processes," he said.
According to Mr. King, in order to predict the results of the occurring processes it is needed to determine whether a similar contraction is in the depths of the earth, develop a range of different geodetic models, neotectonics, a map of faults that will be possible as the installation of 25 new seismic stations.
"To continue the research, stations should be installed at a distance of 5-10 km from each other on the perimeter of the fault. It is necessary to invest in this as much money as has already been invested in the purchase and installation of stations in order to study the processes occurring in the soil, as well as raising of the level of oil reservoirs. All these studies are important in order to determine possible effects of very large deformations that occur to the south of Baku, in order to prepare for a possible earthquake," he said.
