“…The geographical, tectonic, and geomorphological characteristics expose this region to natural hazards that in combination with human activity produce considerable risk (Flores et al 2020). The studied area comprises urban areas within a territorial extension that includes a central city, i.e., Puerto Vallarta, and other administrative and political units that maintain a constant, direct socioeconomic interrelation (Flores et al 2020). Such characteristics de ne the study area as the Puerto Vallarta Metropolitan Area, PVMA.…”

“…However, to perform a seismic hazard assessment, we require an adequate catalog of historical earthquakes to infer possible future earthquakes. In this way, by performing an extensive revision of published articles, Flores et al (2020) and Sawires et al (2020) listed 48 earthquakes of magnitude greater than 6.0 in western Mexico from the 1800s to the present. Figure 1 shows the epicenter location, magnitude, and rupture of some historical earthquakes.…”

“…Flores et al (2020) performed a multicriteria seismic hazard assessment in Puerto Vallarta metropolitan area, Mexico. The main objective of Flores et al (2020) was to implement and evaluate a technique that can be performed for most cities without costly geophysical surveys. In this way, Flores et al (2020) implemented the MCE-SIG approach with selected criteria based on the availability of the data, i.e., peak ground acceleration, type of soil and bedrock, curvature, slope, and ow accumulation.…”

“…Several territory characteristics contribute to the seismic hazard, e.g., soil type, geology, topographic characteristics, peak ground acceleration, soil dynamics, liquefaction potential, groundwater level. Therefore, several authors (e.g., Falcone et al 2020;Flores et al 2020;Giannaraki et al 2018;Gencer 2013; Kossobokov and Nekrasova 2018) consider the seismic hazard and risk assessment a multi-criteria problem based on the territory's information. Therefore, the Multicriteria Evaluation Method within a Graphical Information System, MCE-SIG, constitutes an essential framework for seismic hazard, vulnerability, and risk assessment.…”

“…Consequently, several authors have implemented this methodology to the natural hazards assessment problem (e.g., Chen 2014; Malczewski 2006; Mukhopadhyay et al 2015). Flores et al (2020) performed a multicriteria seismic hazard assessment in Puerto Vallarta metropolitan area, Mexico. The main objective of Flores et al (2020) was to implement and evaluate a technique that can be performed for most cities without costly geophysical surveys.…”

The destructive effects of an earthquake are enhanced when the population is not prepared. The experiences from the past highlighted the importance of proper planning based on adequate scientific data. The Puerto Vallarta metropolitan area (PVMA) comprises medium-sized, rapid-growing urban areas of independent administrative and political entities that maintain a constant, direct socioeconomic interrelation. The PVMA is located in a region with a complex tectonic setting that produces important seismic activity and is affected by beaches, rivers, and estuary systems that produce complex soils and subsoil conditions. Moreover, the PVMA constantly undergoes anthropogenic processes that modify the local geomorphology and produce improper urbanization. Therefore, the PVMA constitutes an ideal natural laboratory to implement and test techniques to estimate seismic hazard, social vulnerability, and seismic risk. These techniques can be later implemented in other similar cities around the world. To determine the seismic hazard, social vulnerability, and seismic risk of the PVMA, we implemented the Multicriteria Evaluation Method within a Graphical Information System considering geomorphological (i.e., bedrock, soil, slope, curvature, flow accumulation), geophysical (peak ground acceleration, shear velocity, vibration frequency), and social information (population density, age, disabilities, health access, housing, and economic activity). We estimate the seismic hazard, social vulnerability, and seismic risk by considering three possible earthquakes. The results indicate a heterogeneous distribution of seismic risk with levels between moderate to high. Finally, a seismic risk microzonation in terms of the percentages of the seismic risk levels is proposed for the Puerto Vallarta metropolitan area.

We performed a seismic vulnerability assessment that involves geotechnical and building structure analysis for Puerto Vallarta, Mexico, a city located along the paci c coast. Like many other Latin American cities, has signi cant seismic risk. We implemented the multi-channel analysis of surface waves and the horizontal-to-vertical spectral ratio methods to estimate shear wave velocity and soil resonance frequency. We considered standard penetration test to determine the penetration resistance and soil classi cation. We also de ned building typologies based on construction materials and structural systems. The VS30 parameter shows that Puerto Vallarta has the three poorest soil classi cations. The resonance frequency parameter shows four zones with different fundamental soil periods. We inferred the building's vulnerability from the coupling between the structural and soil fundamental period and the soil characteristics. The analysis shows several vulnerable buildings scatters within the city, e.g., within the tourist area, con ned masonry buildings from one to ve stories and moment resistance frame buildings up to 12 in the tourist area, poorly con ned masonry houses of one to two stories, and con ned masonry buildings of one to ve stories in the residential/commercial. We present an approach that combines the academic and government to solve a real and transcendental problem since it might directly affect the regulation and structure evaluations in the area. We are sure that these exercises are of great interest in urban growth areas in other parts of the world, especially in Latin America, to achieve seismic risk mitigation.
