  The Jalisco region of western Mexico is the locus of interaction among the
North America, Cocos, and Rivera plates, giving rise to the Jalisco block. This
region is one of the most tectonically active in Mexico, and here took place
the largest instrumentally recorded earthquake in Mexico the twentieth century,
on 3 June 1932 (M 8.2), three important tsunamis in the last 100 yrs, and two
of the most active volcanoes in Mexico. Nevertheless, the first seismicity
studies here, undertaken with temporary networks, did not commence until 1994.
In 2008, the Government of Jalisco and the University of Guadalajara funded a
research project to install a seismic network in this region. The principal
objective was to study the seismic hazard in the region and characterize
seismic parameters in the different areas to design building codes. The Red
Sismica y Acelerometrica Telemetrica de Jalisco (RESAJ) project was thus
initiated in 2009. Its Central Lab is at Centro de Sismologia y Volcanologia de
Occidente (SisVOc), located at the Universidad de Guadalajara in Puerto
Vallarta. Currently, the RESAJ has 26 telemetered and 2 autonomous stations.
The RESAJ serves as the seismological lab for the postgraduate program at
SisVOc.
