Abstract

On 9th October, 1995, at 9:36 local time, an earthquake of magnitude 8.0 occurred on the west coast of Mexico. The epicenter was located at 18$^{\circ}$ 51.5' N and 104$^{\circ}$ 8.4' W, at approximately 25 km of Manzanillo. This important commercial harbor is connected by a narrow channel to a lagoon. A tidal gauge recorded the forced oscillations occurred in the lagoon. A dominant period of 36 minutes was observed. Analytical solutions for ideal rectangular flat basins and numerical modeling for realistic geometries show that the lagoon and the channel produce a Helmholz resonance with a period similar to that observed in the earthquake.
