Relationship between MMI Data and Ground Shaking in the State of Nuevo León, Northeastern Mexico

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

“…La sismicidad documentada dentro de la Sierra Madre Oriental es de baja a moderada magnitud (Figura 2). Algunos de estos sismos han sido percibidos en centros urbanos localizados a lo largo de la cadena montañosa (Montalvo-Arrieta et al, 2015). En la proximidad al CSR, la actividad sísmica recientemente registrada y de mayor intensidad se asocia con 63 sismos que ocurrieron en el frente tectónico de la SMO de julio a diciembre del 2012, con magnitudes en el rango de 2.8 ≤ M ≤ 3.6 e hipocentros a 8 ±5 km de profundidad (Gómez-Arredondo et al, 2016).…”

Evaluation of macroseismic intensities in Mexico from recent earthquakes using ¿Sintió un sismo? (Did you feel it?)

“…Houses damaged were reported in some communities near the epicentral area and in the Monterrey Metropolitan Area (MMA), located approximately 90 km northwest of the epicentral zone, where strong ground shaking was described by the population. Montalvo-Arrieta et al (2015) analyzed intensities from this earthquake; they reported a total of 144 received web questionnaires, 137 of them from the MMA. The descriptions by citizens in the epicentral area correspond to the highest community internet intensity (CII) values, V-VI.…”

“…The interest in earthquake intensity data is fomented by: (a) the use of internet as a tool to collect very rapidly large amounts of macroseismic data; (b) the recent development of new algorithms to analyze intensity data; and (c) the need to obtain the source parameters of historical earthquakes to improve our understanding of vulnerability, seismic hazard and seismic risk (e. g., Singh et al, 1996;Suter et al, 1996;Bakun and Wentworth, 1997;Zobin and Ventura-Ramírez, 1998;Suter, 2001;Atkinson and Wald, 2007;Wald et al, 2011;Hough, 2012;Hough, 2013;Suter, 2015). ¿Sintió un sismo?, is a web questionnaire that was initially implemented in northeastern Mexico as a tool for the evaluation of ground shaking in a region with few seismological observatories, such as the State of Nuevo León (Montalvo-Arrieta et al, 2015). However, after its implementation on the web, several reports of users located in several regions of Mexico were also received.…”

Relocation and seismotectonic interpretation of the seismic swarm of August - December of 2012 in the Linares area, northeastern Mexico

“…Although large intraplate earthquakes are rare, these infrequent events can be extremely devastating because the cities in stable continental region are seismically poorly prepared. These earthquakes can also cause widespread damage because the attenuation of seismic energy is relatively low in plate interiors (Hanks and Johnston, 1992;Crone et al, 2003;Montalvo-Arrieta et al, 2015).…”
