dc.description.abstract | New estimates of long-term velocities of permanent GPS stations in Southern Mexico
reveal that the geologically discernible 650-km long shear zone, which strikes parallel
to the Middle America trench, is active. This left-lateral strike-slip, La Venta–Chacalapa
(LVC) fault system, is apparently associated with a motion of the Xolapa terrain and at
the present time is the northern boundary of a 110–160-km wide forearc sliver with a
sinistral motion of 3–6 mm/year with respect to the North America plate. This sliver is the
major tectonic feature in the Guerrero and Oaxaca regions, which accommodates most
of the oblique component of the convergence between the Cocos and North America
plates. Previous studies based purely on the moment tensor coseismic slips exceedingly
overestimated the sliver inland extent and allocated its northern margin on or to the north
of the Trans-Mexican Volcanic Belt. While the LVC fault system probably slips slowly
over geologic scale time and there is not any historic evidence of large earthquakes on
the fault so far, its seismic potential could be very high, assuming a feasible order of
103 years recurrence cycle. A detailed analysis of long-term position time series of
permanent GPS stations in the Guerrero and Oaxaca states, Southern Mexico discards
previous models and provides clear evidence of an active LVC fault zone bounding the
Xolapa forearc sliver. The southeastward motion of this sliver may have persisted for
the last 8–10 Million year and played an important role in the tectonic evolution of
the region. | pl_PL |
