“…Trabajos recientes vinculados a la temática (Khan et al, 2021;Shafique et al, 2018;Touhami et al, 2021;Wen et al, 2018) indican que las propiedades del terreno más empleadas en el análisis del efecto de sito con base en datos de geología superficial, serían las propiedades geotécnicas, espesores de capas, aflorabilidad de los materiales y el comportamiento de ondas de corte (Vs). De acuerdo con la experiencia acumulada en los trabajos citados anteriormente y en función del nivel de conocimiento del subsuelo de la ZMVT, para el análisis de la susceptibilidad sísmica se emplearán: Tabla 1.…”

La creación de herramientas que faciliten la gestión de los riesgos en los territorios, se ha convertido en una tarea esencial. La investigación, da el primer paso en el conocimiento de la respuesta símica local en la Zona Metropolitana del Valle de Toluca. El objetivo consistió en cartografiar la disposición espacial de los suelos y rocas, y analizar su posible respuesta sísmica local. La metodología, incluye: (1) Crear el modelo 3D que represente la disposición espacial de los materiales geológicos, (2) Clasificar desde la óptica de la susceptibilidad sísmica cada tipo litológico y representarlo espacialmente y (3) Zonificar el periodo dominante del suelo mediante ecuaciones empíricas. El trabajo se diseñó sobre herramientas SIG y se soporta sobre 231 puntos de documentación (perforaciones y descripciones de afloramientos). La cartografía resultante revela tipos litológicos de diferentes características, derivando en cuatro niveles de susceptibilidad sísmica y cinco rangos de periodos dominantes.

“…However, it only started to gain significant interest from the international scientific community after the catastrophic disaster of Mexico City during the Michoacán Mexico earthquake in 1985, where strong amplification due to soft clay layers caused many high‐rise buildings to collapse despite their long distance from the seismic source (Singh et al., 1988). In the past few decades, studies of site effects on seismic ground motions induced by surface geology and subsurface structures have pushed the science forward (Bard, 1994; Wen et al., 2018), and the quantification of ground motion amplifications became important for seismic hazard mitigation programs making site effect estimation studies, which is a common practice in engineering seismology. These site effects can be estimated by several methods based on strong motion earthquake recordings (Heng et al., 2011; Kagawa et al., 2017), passive ambient noise microtremor measurements (Karagoz et al., 2015; Yamanaka et al., 1993; Zaineh et al., 2012) or numerical simulations, and theoretical experimental methods (Amrouche et al., 2014; Chaillat et al., 2009; Tsai et al., 2017).…”

Variability in earthquake ground motions is significantly related to the local geological conditions immediately beneath a specific investigation site. Seismic waves propagating within the geological formations will either be amplified or attenuated at given frequencies, depending on different physical parameters such as wave propagation velocities, the impedance between layers, the thicknesses of the different geological formations, the shape of the sedimentary basins, or the local surface topography (

A review of the microtremor horizontal-to-vertical spectral ratio (MHVSR) method

et al. 2022

The single-station microtremor horizontal-to-vertical spectral ratio (MHVSR) method was initially proposed to retrieve the site amplification function and its resonance frequencies produced by unconsolidated sediments overlying high-velocity bedrock. Presently, MHVSR measurements are predominantly conducted to obtain an estimate of the fundamental site frequency at sites where a strong subsurface impedance contrast exists. Of the earthquake site characterization methods presented in this special issue, the MHVSR method is the furthest behind in terms of consensus towards standardized guidelines and commercial use. The greatest challenges to an international standardization of MHVSR acquisition and analysis are (1) the what — the underlying composition of the microtremor wavefield is site-dependent, and thus, the appropriate theoretical (forward) model for inversion is still debated; and (2) the how — many factors and options are involved in the data acquisition, processing, and interpretation stages. This paper reviews briefly a historical development of the MHVSR technique and the physical basis of an MHVSR (the what). We then summarize recommendations for MHVSR acquisition and analysis (the how). Specific sections address MHVSR interpretation and uncertainty assessment.
