“…Bounding faults in the NCG dip 70° toward the graben axis, the relief of their fault scarps is up to 1-2 km, and the mean displacement rate is up to 1-3 mm/year [26,27,31]. The kinematics of these faults is normal with a minor right-lateral strike-slip component of motion, consistent with a minimum principal stress oriented from E-W to NW-SE [26][27][28]31]. Figure 2a, with the location of the 2012 fissures (modified from [32]).…”

“…The neotectonic activity, seismic shacking, compaction of unconsolidated recent sediments and human activities, like water withdrawal and ground loading within these basins, have been considered as the principal causes of the occurrence of ground subsidence and subsequent soil fissuring in the urban areas of the TMVB [17,18,23]. CG, with a population of about 100,000 inhabitants, is located in the Mexican state of Jalisco, at 1500 m a.s.l., inside the Colima Rift, which is the southern branch of the Colima-Tepic-Chapala triple junction in the western sector of the TMVB [17,[25][26][27][28][29][30][31] (Figure 1). [32]).…”

Land subsidence, Ground Fissures and Buried Faults: InSAR Monitoring of Ciudad Guzmán (Jalisco, Mexico)

Abstract:We study land subsidence processes and the associated ground fissuring, affecting an active graben filled by thick unconsolidated deposits by means of InSAR techniques and fieldwork. On 21 September 2012, Ciudad Guzmán (Jalisco, Mexico) was struck by ground fissures of about 1.5 km of length, causing the deformation of the roads and the propagation of fissures in adjacent buildings. The field survey showed that fissures alignment is coincident with the escarpments produced on 19 September 1985, when a strong earthquake with magnitude 8.1 struck central Mexico. In order to detect and map the spatio-temporal features of the processes that led to the 2012 ground fissures, we applied InSAR multitemporal techniques to process ENVISAT-ASAR and RADARSAT-2 satellite SAR images acquired between 2003 and 2012. We detect up to 20 mm/year of subsidence of the northwestern part of Ciudad Guzmán. These incremental movements are consistent with the OPEN ACCESS Remote Sens. 2015, 7 8611 ground fissures observed in 2012. Based on interferometric results, field data and 2D numerical model, we suggest that ground deformations and fissuring are due to the presence of areal subsidence correlated with variable sediment thickness and differential compaction, partly driven by the exploitation of the aquifers and controlled by the distribution and position of buried faults.

“…En un estudio detallado de los distintos sistemas de fallas entre Guadalajara y la boca del Golfo de California, Ferrari y Rosas-Elguera (2000) concluyen que el rift Tepic-Zacoalco está constituido por una serie de grábenes y semigrábenes desarrollados en distintos episodios a partir del Mioceno tardío. Las estructuras más meridionales del rift Tepic-Zacoalco (graben de Puerto Vallarta, semigraben de Amatlán de Cañas, falla de San Marcos y zona de fallas de Zacoalco) muestran evidencias geológicas (Ferrari et al, 1994;Rosas-Elguera et al, 1997) y sismológicas (Suárez et al, 1994;Pacheco et al, 1999) de actividad neotectónica durante el Cuaternario. Con base en la batimetría de la región marina frente a Puerto Vallarta, Alvarez (2002) también propone la existencia de una zona de fallamiento normal activo en la Bahía de Banderas que parece estar confi rmada por la pronunciada actividad sísmica registrada en la zona durante los últimos años (Núñez-Cornú et al, 2002).…”

C i e n A ñ o s ResumenLa extraordinaria diversidad magmática de la Faja Volcánica Transmexicana está controlada (directa o indirectamente) por dos placas oceánicas independientes cuyos parámetros geofísicos y composicionales se modifi can constantemente a lo largo de la trinchera, por un régimen tectónico esencialmente distensivo que opera con distinta intensidad sobre la placa continental, por un basamento cortical con diferentes edades, espesores y composiciones, y por una fuente mantélica primaria de composición extremadamente variable que ha sido infl uenciada, en mayor o menor medida, por los agentes químicos derivados de la subducción. El régimen tectónico convergente y, en consecuencia, el arco magmático, tampoco han evolucionado de forma homogénea a lo largo su historia, sino que han mostrado transformaciones notables en su posición, geometría y composición. Por estos motivos, la Faja Volcánica Transmexicana es el resultado de uno de los sistemas tectónicos convergentes más complejos del planeta, el objeto de más de un siglo de investigaciones científi cas, y también el centro de las controversias más notables sobre la geología mexicana.Palabras clave: Faja Volcánica Transmexicana, México, subducción, arco magmático, petrología ígnea, manto, corteza.

“…In the east the Jalisco block is bounded by the Colima rift zone, a graben that experienced 1.5-3.3 kI of extension since the early Pliocene (Allan, 1986) and is stil active (Suarez et al, 1994). The submarne Manzanilo canyon bounds the Jalisco block to the southwest and is interpreted as the offshore extension of the Colima rift zone (Khutorskoy et aI., 1994).…”
