Resumen:
Valley of Mexico (VM) Seismic Network-Red Sismica del Valle de Mexico
(RSVM) is a regional digital network deployed by Instituto de Geofisica,
Universidad Nacional Autonoma de Mexico(UNAM). It started at 1996 with
some vertical short-period instruments scattered across the valley,
which since 2006 were gradually replaced by three-component
intermediate, broadband, and more recently accelerographic instruments.
It presently counts 28 stations, representing a contribution to the new
generation of regional seismic networks in Mexico with the goal of
densifying the coverage throughout the known seismic zones in the
country. Along 11 yrs of operation with threecomponent sensors, this
network has recorded numerous local and regional earthquakes. Seismicity
recorded by RSVM has illuminated major seismic areas inside the valley
and the style of faulting of this activity, having for the first time a
focal mechanism catalog of this zone of the country. The recent
upgrading of 16 out of 31 stations with accelerometers has provided, in
real time, the strong ground motion in Mexico City generated by great
earthquakes (M >7) that occurred outside of the valley, having important
implications to civil protection purposes. The results obtained up to
now highlight the need to complete the upgrade of the rest of the
stations, as well as densifying the network to deepen our knowledge of
the structure of VM.
