Twelve of the ground anchors of the structure were monitored since its construction with vibrating wire load cells. Some of them suffered component damage and vandalism, but we can still get data from seven of them after 14 years of performance. An automated data recollection system was put in place (a data logger) and it was assembled with a seismic switch with a set of acceleration of 0,07g. It allowed to measure the load of the ground anchors in the seismic event of 27th of February of 2010. The measurements indicate us what was formulated in some papers before, that the load variation was very low (below 3%) due to two facts: the free length of the anchors that influences in reducing the response to differential displacements between extremes of the free length of an anchor (anchor head and fixed length) and a possible block behavior of the anchored wall.
