“…This neotectonic feature could be the eastern boundary of the alleged South Mexican Block. The locations of the earthquakes of 1959, 1967 and 2009 roughly coincide with the fault trace proposed by Andreani et al (2008). Moreover, their focal mechanisms suggest a slight strike-slip component that could be related with the strike-slip motion of the Veracruz Fault.…”

“…Suárez and López (2011) López (2011) neither accepted nor rejected that all these events (including that of 1959) have a same tectonic origin. Andreani et al (2008), using PEMEX seismic profiles, digital elevation models, satellite imagery and field observations, proposed the existence of a major left lateral fault, calling it Veracruz Fault (Figure 2). This neotectonic feature could be the eastern boundary of the alleged South Mexican Block.…”

The southwestern corner of the Gulf of Mexico (around the Isthmus of Tehuantepec) is exposed to intense deep (> 100 km) seismic activity caused by the subduction of the Cocos Plate. Aside from this, the gulf has been considered a zone of low or no-seismicity. However, a sparse shallow seismic activity is observed across the Gulf of Mexico, even in the most distant areas from the plate boundaries. Some of these earthquakes have been strongly felt (e. The recent improvements of the Mexican Seismological broadband network have allowed the recording of small earthquakes distributed in the Gulf of Mexico. Although intermediate and large earthquakes in the region are infrequent, historic evidence indicates that magnitudes could reach Mw ~6.4. This fact should be taken in consideration to reassess the seismic hazard for industrial oil infrastructure in the region.Keywords: Strike-slip faulting, East Mexican Fault, intra-slab seismicity, salt tectonics, gravity sliding, seismic hazards.

“…4c and d) have attempted to explain both the eastward escape of the Caribbean Plate as described by Lyon-Caen et al (2006) and tectonics of the Sierra Madre de Chiapas. Andreani et al (2008b) suggested a connection between the strike-slip faults of Chiapas; the Veracruz shear zone, which affects the Veracruz Basin further north; and the transtension of the Mexican volcanic arc (Fig. 4c).…”

Abstract. We use a geomorphic approach in order to unravel the recent evolution of the diffuse triple junction between the North American, Caribbean, and Cocos plates in northern Central America. We intend to characterize and understand the complex tectonic setting that produced an intricate pattern of landscapes using tectonic geomorphology, as well as available geological and geophysical data. We classify regions with specific relief characteristics and highlight uplifted relict landscapes in northern Central America. We also analyze the drainage network from the Sierra Madre de Chiapas and Maya Mountains in order to extract information about potential vertical displacements.Our results suggest that most of the landscapes of the Sierra Madre de Chiapas and Maya Mountains are in a transient stage. Topographic profiles and morphometric maps highlight elevated relict surfaces that are characterized by a low-amplitude relief. The river longitudinal profiles display upper reaches witnessing these relict landscapes. Lower reaches adjust to new base-level conditions and are characterized by multiple knickpoints.These results backed by published GPS and seismotectonic data allow us to refine and extend existing geodynamic models of the triple junction. Relict landscapes are delimited by faults and thus result from a tectonic control. The topography of the Sierra Madre de Chiapas evolved as the result of (1) the inland migration of deformation related to the coupling between the Chiapas Massif and the Cocos forearc sliver and (2) the compression along the northern tip of the Central American volcanic arc. Although most of the shortening between the Cocos forearc sliver and the North American Plate is accommodated within the Sierra de Chiapas and Sierra de los Cuchumatanes, a small part may be still transmitted to the Maya Mountains and the Belize margin through a "rigid" Petén Basin.

Evidence of a collision between the Yucatán Block and Mexico in the Miocene

S U M M A R YWe present the evidence for an anomalous southwest-dipping slab in southern Mexico. The main evidence comes from a clear receiver function image along a seismic line across the Isthmus of Tehuantepec and is also supported by a previous global tomographic model. The slab dips at 35 • , is approximately 250 km in length and appears to truncate the Cocos slab at about 120 km depth. We hypothesize that the slab was created by subduction of oceanic lithosphere prior to the collision of the Yucatán Block with Mexico at approximately 12 Ma. This scenario would explain the Chiapas Fold and Thrust Belt as the product of this collision, and its age constrains the date of the event to be in the Miocene.
