Abstract: Historical seismological information in Mexico indicates that, in the Guerrero Seismic Gap, which extends for 150 kilometers along the Costa Grande, from Papanoa to Acapulco, there have been no ruptures due to tectonic movements for more than 110 years, which is why the possibility of a large-magnitude earthquake remains latent. In this work, 288 hypothetical earthquakes that could occur in this area were defined and, through numerical models of the propagation of the initial free surface of the tsunami, flood risk zones and currents were determined in the coastal area of Acapulco, Mexico. According to the results, it was estimated that, for Acapulco Bay, the average arrival time of the maximum height of the tsunami is 30 minutes, which reaches a maximum distance of 800 m.
