Geodesy and crustal deformations are closely related. On the one hand, geodetic techniques are used to estimate deformations contributing in this way to geology, seismology and geodynamics. On the other hand, deformations consist a major challenge in the maintenance of geodetic reference frames. In this work we use GNSS (Global Navigation Satellite System) data and geodetic methods to estimated crustal deformations in the area of Aetolia-Acarnania, western Greece. The analysis of measurements that have been conducted in 2007 and 2023 on trigonometric points showed significant horizontal deformations up to 16.8 cm. The revealed deformations are presented and discussed in terms of their impact on the realization of the national coordinate reference system.
