Abstract
In this work, we present preliminary results of a reconstruction of the Güevéjar landslide (Granada, south Spain) during the 1755 Lisbon and 1884 Andalusian earthquakes. We perform a back‐analysis of the landslide to estimate the static safety factor and the critical
acceleration previous to both earthquakes and for the present‐day situation. We obtain a critical intensity of V which matches the minimum intensity grade required to trigger coherent landslides. We conclude that the Güevéjar landslide is stable at present‐day conditions but its
reactivation is expected in case of an earthquake with a similar intensity to that during the 1884 Andalusian earthquake (I=VI‐VII) or larger.
