CIRES (for Centro de Instrumentación y Registro Sísmico in Spanish) Civil Association is a non-profit civil association founded in June 1986, originally sponsored by the Javier Barros Sierra Foundation until 2002 to promote the research and development of technology applied to Seismic Instrumentation, as a useful way to mitigate potential seismic disasters, such as Mexico City experienced in 1985.


The Mexico City government authorities have sponsored, the design and development of the current Acelerograph Network for Mexico City since its inception in 1987.CIRES is responsible for this technological resource, which has allowed the collection of information facilitate understanding and eventually adapting the seismic design of the construction regulations of Mexico City.

CIRES developed SAS (Sistema de Alerta Sísmica) to give warnings about the effect of the big earthquakes that happen on Guerrero's coast, with the sponsorship of SOS (Secretaría de Obras y Servicios), in December 1989. SAS has been in operation since 1991 and became a public service in the year 1993.


To warn the effect that cause the big earthquakes that happen eventually on the Guerrero's coast, with the sponsorship of SOS (Secretaría de Obras y Servicios), in December 1989, CIRES developed SAS (Sistema de Alerta Sísmica), in operation since 1991 and to become as public service in the year 1993

After the earthquakes that Oaxaca suffered in 1999 CIRES developed new seismic instrumentation work on the Sistema de Alerta Sísmica de Oaxaca (SASO) was begun in 2000, SASO has been in operation since 2003 with the support of this state’s government.

Thanks to the Oaxaca authorities, the Chief Government of Mexico City, and the participation of Ministry of the Interior (SEGOB, Secretaría de Gobernación), SAS and SASO have been integrated as the first phase of the development of SASMEX® (Seismic Alert System Of Mexico).

Additionally, the project of broadening coverage of seismic hazard begun to reach the coasts of Jalisco, Colima, Michoacán, Guerrero, Oaxaca and the state of Puebla. This allows SASMEX® to alert Mexico City more effectively before earthquakes which could generate damage.

Furthermore CIRES has proposed to Federal Government that it broadcast SASMEX® warnings to other vulnerable cities and also to extend the coverage of the seismic hazard in Veracruz, Oaxaca and Chiapas.


To disseminate SASMEX® warnings, CIRES developed two receptors.The first is the SASPER (Sistema de Alerta Sísmica Personalizada). This receptor is used in radio, television, head offices of Government, also public and private elementary schools, universities and additionally in the Mexico City subway.

Since 2012 the signal of the SASMEX® is also received automatically by the second receptor SARMEX® developed by CIRES, it operates silently and only generates an audible alert when danger approaches. Currently they are distributed in the city’s public schools, but they can be acquired by individuals as well.

CIRES researches and develops digital systems for accessible measurement and recording, to understand and analyze the dynamic behavior of soils and structures subject to earthquake action, such as: the Data Acquiring Card (RAD), and the Digital Accelerograph System for Structures SADE.

To promote the training of specialist, CIRES organizes seminars, courses, conferences and events, allowing the dissemination of knowledge about of seismic events measurement. It also performs internal technological development projects with engineering students, who do their social service and develop their professional theses there.



SASMEX® is a useful resource for efficient design and practice of earthquake drills to reduce seismic vulnerability. SASMEX® notices are disseminated in the majority of commercial radio and television stations; SASPER and SARMEX® receptors.


CIRES disseminates its work in specialized conferences about earthquake engineering and early warning systems in Mexico and abroad, also collaborates with specialized institutions and publishes its work in peer-reviewed scientific journal and manuals.

CIRES has partnered with international institutions such as:
- International Association of Seismology and Physics of the Earth's Interior, IASPEI
- United States Geological Survey, USGS
- Electric Power Research Institute, EPRI
- EQE International
- American Geophysical Union, AGU
- Centre National de la Recherche Scientifique CNRS, France.

CIRES is a member of the Sistema de Protección Civil de la Ciudad de México (Council of Civil Protection of the Mexico City) and it is registered in the RENIECYT (Registro Nacional de Instituciones y Empresas Científicas y Tecnológicas) belonging to CONACyT (Consejo Nacional de Ciencia y Tecnología).
