TY - JOUR T1 - The Vertical Pattern of Surface Deformation in Iran, Inferred from the GPS Measurement Campaigns TT - تعیین الگوی تغییر شکل ارتفاعی سطح پوسته زمین در فلات ایران با استفاده از داده‌های شبکه GPS موردی ایران سراسری JF - kntu-jgit JO - kntu-jgit VL - 1 IS - 1 UR - http://jgit.kntu.ac.ir/article-1-56-en.html Y1 - 2013 SP - 47 EP - 64 KW - Deformation analysis KW - GPS KW - Analytical deformation analysis KW - vertical Deformation N2 - Using the theory of analytical surface deformation analysis, the Earth's vertical surface deformation has been analyzed for Iran. Iran Global GPS campaign is used for the mentioned purpose. This network is the first regional GPS one in Iran which was designed and measured within a scientific cooperation between the National Cartographic Center of Iran and the University of Montpellier in France. The network measurements have been carried out in three successive epochs: 1999, 2001 and 2005. GAMIT/GLOBK GPS processing package has been used for processing the corresponding code and carrier phase measurements. To analyze vertical deformation in Iran, the change in the Gauss's second fundamental form and a measure for the change in curvature, mean curvature here, is used. Using the other available evidences such as focal mechanism solutions of the seismic events which have occurred during the observation period of this study has been verified.
