Is Puerto Vallarta a Seismic Zone? Earthquake Risk Explained

Yes, Puerto Vallarta is a high-risk seismic zone on the coast of Jalisco, very close to the boundary of the Rivera plate, a small oceanic plate that dives beneath the North American plate. This tectonic corner, where the Rivera, Cocos and North American plates converge, is one of the most complex and active in Mexico's Pacific region, capable of producing both large subduction earthquakes and closer, shallower coastal quakes.

The region has already experienced one of the largest earthquakes in Mexican history: the 1932 Jalisco-Colima earthquake, estimated near magnitude 8.2, which generated a tsunami that struck the coast. Puerto Vallarta also feels earthquakes originating off the coasts of Jalisco and Colima, and the city, sitting on the Bay of Banderas, is potentially vulnerable to tsunamis because of its coastal location and terrain.

Because of its proximity to the Rivera plate subduction zone, Puerto Vallarta is classified within Mexico's high seismic-hazard zones. The bay's rapid tourism and hotel growth makes compliance with earthquake-resistant building codes, along with tsunami-warning protocols along the coastal strip, especially important.
