ROSABAL-DOMINGUEZ, Sandra; RIVERA-ALVAREZ, Zulima  e  VILLALON-SEMANAT, Madelín. Site effect at the accelerograph units from Santiago de Cuba city by using strong movements. Min. Geol. [online]. 2022, vol.38, n.3, pp. 210-222.  Epub 30-Set-2022. ISSN 1993-8012.

An analysis of the site effect at accelerograph units from Santiago de Cuba is carried out for the first time in Cuba; using accelerograph records of strong movements corresponding to the Haiti earthquake on August 14, 2021 of magnitude 7.2. The method of direct interpretation of the Fourier transform is used. The main results show that the APTO station, located on the soft soil of marine deposits, beach sand and pebbles, and storm banks, shows the highest amplitude values (APTO 69.625), as well as the highest period values (0.430 s ), compared to the ABON station (0.195 s). The maximum frequency value (5,139 Hz) corresponds to the ABON station.
