Mexico

The Mexican government decreed the establishment of the National Seismological Service (Servicio Sismológico Nacional – SSN) on September 5, 1910. At that time the SSN was under the charge of the National Geological Institute under the Ministry of Mines and Development.
Between 1910 and 1923 seismic stations were installed in Tacubaya, DF and in the cities of Oaxaca, Merida, Chihuahua, Veracruz, Guadalajara, Monterrey and Zacatecas. Seismographs were “Wiechert” made in Germany. Seven of these are still operating today and are probably the oldest system of America, which have operated continuously.
Since 1992, the modernization of the National Seismological Networkwith has been undertaken with budgetary support from the Ministry of Interior and the Universidad Nacional Autónoma de México. Thus was born the network Broadband Seismological Observatory. Today the SSN has 22 seismic observatories across the country and plans to expand the network to 33 observatories.
