A first-order seismotectonic regionalization of Mexico for seismic hazard and risk estimation

The Mitla Landslide, an Event That Changed the Fate of a Mixteco/Zapoteco Civilization in Mesoamerica

“…The seismicity reported by the Servicio Sismológico Nacional (SSN) and presented in Figure 2(c) corresponds to the intraplate events zone in the south-east zone of México named by Zúñiga et al [5] as NAM and matches the intraplate seismicity of the southeastern zone of México that is not related to the volcanism of the Trans Mexican Volcanic Belt; its maximum depth has been measured at 20 km.…”

“…It is important to mention that regarding recurrence periods for the central zone of the State of Oaxaca, Zúñiga et al [5] report periods of 6 years for quakes with magnitudes above 5 occurring in the NAM zone (shallow events with depth under 20 km), periods of 109 years for magnitudes above 7 taking place within the subducted Cocos plate (intraplate events with depths of 40 to 180 km), and periods of 37 years for quakes of magnitudes above 7.5 occurring in the coupling zone of the Cocos and North American tectonic plates (subduction area).…”

Inventario de movimientos en masa en el sector sur de la Saliente de Monterrey. Caso de estudio: cañón Santa Rosa, Nuevo León, noreste de México

“…Registros históricos de sismicidad a lo largo de la traza de la Sierra Madre Oriental indican un gran potencial sismogénico a lo largo de esta provincia (Galván-Ramírez y Montalvo-Arrieta, 2008; Ramos- Zúñiga et al, 2012). La probabilidad de que se presente sismicidad de elevada magnitud (M≥6.5) es considerable (Zúñiga et al, 2017), constituyendo escenarios sísmicos críticos de peligro por movimientos en masa regional así como potenciales daños en otros sectores debido a la propia sacudida del terreno (Salinas-Jasso et al, 2017).…”

“…Pese a su baja magnitud, varios de los eventos fueron percibidos por habitantes de comunidades rurales asentadas dentro del CSR, incluso reportando daños menores en casas y propiedades (Gómez-Arredondo et al, 2016; datos nuestros no publicados). Se han propuesto potenciales sismos de mayor magnitud (M≥6.5) a partir de la documentación de catálogos sísmicos (Galván-Ramírez y Montalvo-Arrieta, 2008;Zúñiga et al, 2017) serias afectaciones a la infraestructura civil e incluso pérdida de vidas en varias ciudades asentadas sobre las zonas montañosas (e.g., área metropolitana de Monterrey; Salinas-Jasso et al, 2017).…”

Active Faults sources of the Morelia-Acambay Fault System, Mexico based on Paleoseismology and the estimation of magnitude <i>M<sub>w</sub></i> from fault dimensions

“…represent those that had have studies of paleoseismology. The seismicity, represented by circles, was taken from the catalog of the Mexican Seismological Survey (SSN), focal mechanism from Krishna-Sing et al (2012),Ego and Ansan (2002) andPacheco et al (1999) the magnitude homogeneous catalog including historical events presented by Magaña-García (2017) andZúñiga et al (2017), wich includes earthquakes since 1912 to 2016.…”
