Analysis of the Current Dynamic of the Jalisco Block, Mexico through GNSS Observations

Abstract

Mexico is surrounded by a highly dynamic tectonic environment, where the area of greatest influence is in the west, since it is where large earthquakes occur and tectonic blocks are generated due to the subduction of two oceanic plates in the North American plate. In the present study, the horizontal velocities of 15 GNSS stations of continuous operation are calculated, over a period of 11 years, which are located within the Jalisco Block, Mexico with the objective of analyzing the current dynamics of this tectonic block, which is mainly influenced by the oblique subduction of the Rivera plate.
