Abstract

The map of tectonic plates frequently used in textbooks include 14 plates previously described by Uyeda in 1978 that were also used by NUVEL 1 and NUVEL 1A models. These kinematic models, the most widely used between 1990 and 2010, allowed calculating the relative velocity among these 14 major tectonic plates. The spatial geodesy, mainly GPS data, offers a more detailed picture of how our planet works. In recent years, the MORVEL-56 model has been published, which divides the lithosphere into 56 tectonic plates. Integrating geological, geophysical and geodetic data, this kinematic model estimates the relative velocity among these 56 plates and offers a more realistic picture of the present tectonic activity of our planet. We describe in this work, as an example, the current geodynamic setting of the Eastern Mediterranean and the Arabian Peninsula.
