IMPORTQANT CONTRIBUTION OF THE AZERBAIJANI SCIENTISTS TO THE WORLD SCIENCE
February 20, 2020
The paper “Preliminary reference Earth model” was published in the peer reviewed journal “Earth and Space Science” of the American Geophysical Union (AGU). The co-authors are the head of Department of the ANAS Institute of Geology and Geophysics, academician Hatam Guliyev and corresponding member of ANAS Rashid Javanshir.
It should be noted that the Preliminary reference Earth model (PREM) was presented by the President of the American Geophysical Union D. Anderson and the outstanding professor A. Dzevonsky to the international scientific community in 1981. In 1989, the scientists were awarded the Crowdof Prize for this study (in the field of Earth sciences this prize is equivalent to the Nobel Prize). So far, this model has been used for solving many geological and geophysical problems.
After 40 years, two Azerbaijani scientists challenged the validity of PREM in terms of nonlinear geomechanics. In their paper, Azerbaijani scientists proved that the model is not geomechanically correct, and they established infidelities and errors of previous PREM due to creating method of nonlinear geomechanical analysis. A long-term plan for future researches was also developed.
The carried out studies play fundamental role and also have great innovative potential in the study of oil and gas fields and the seismicity of the region.
