The mission of the SSN is to determine with opportunity the
seismic parameters of earthquakes that strike the Mexican
area. This information is crucial for the authorities to initiate
different mechanisms oriented to mitigate the effects of
the seismic activity in the population.

National Broadband Seismic Network
SSN Seismic Network
The seismic monitoring of the Mexican area is done through four networks:
- one continental network named National Broadband Seismic Network.
- one metropolitan named Mexican Valley Network deployed around Mexico City.
- two local networks: the Tacana Volcano and the Socorro Island.
SSN Seismic Station
The core for the National Broadband Seismic Network is composed with stations
equiped with Quanterra dataloggers, seismometers STS-2, and accelerometers
Episensor ES-T. For real time transmission at rural areas, the SSN uses a VSAT
station.
