The city of Puerto Vallarta is located at Bahía de Banderas on the 8 northern coast of Jalisco., Currently there exists a Seismic Gap in the Northern 9 coast of Jalisco (Vallarta Gap). Historically seismogenic tsunamis have affected 10 the coast of Jalisco. In this work, the risk due to a local tsunami in the city of 11 Puerto Vallarta is a function of the interaction between hazard and 12 vulnerability. We model the tsunami hazard, generation and propagation, using 13 the initial conditions for a great earthquake (Mw ≥ 8.0) similar to those that 14 occurred in 1787 at Oaxaca and in 1995 at Tenacatita Bay, Jalisco.
