Department of Geophysics, Faculty of Physical and Mathematical Sciences, University of Chile, home to the CSN

The National Seismological Center of the University of Chile, (Spanish: Centro Sismológico Nacional de la Universidad de Chile (CSN)[1]) is part of the Faculty of Physical and Mathematical Sciences of the University of Chile.[1][2] The center delivers information about seismic activity from Chile to the National Office of Emergency at the Ministry of the Interior (ONEMI), Hydrographic and Oceanographic Service of the Chilean Navy (SHOA), and the general public.[3] The current director of The CSN is Sergio Barrientos Parra.[4][5]

History

Real-time monitoring of seismic events 2012

El Centro Sismológico Nacional, originally named the "Chilean Seismological Service", was conceived by a former director of the University of Chile, Valentín Letelier, after a significant earthquake that ravaged Valparaiso in 1906. The impact of the earthquake highlighted the urgent need for a seismological organization. Pedro Montt, the former president of Chile, eventually founded the CSN on May 1, 1908.[6]

Fernand de Montessus de Ballore (June 19, 1851 – January 31, 1923) was a seismologist, army veteran, and the first director of the CSN. The first seismological station ran by the CSN was installed in 1869 on the Santa Lucía Hill in Santiago. It was designed as the central hub of a national network with additional stations installed in the surrounding areas of Tacna, Copiapó, Osorno, and Punta Arenas.[2] A total of 29 stations were added in 1909. The system also collected testimonies from observers, including telegraphers, lighthouse guardians, railway workers and volunteers.[7]

In 1927, the service was absorbed into the University of Chile[8] under the Department of Geophysics (DGF). In 2013, the name was officially changed to Centro Sismológico Nacional (CSN).[9] The CSN is the official technical body in charge of monitoring seismic activity throughout the national territory. The mission of the CSN is to deliver quality seismological data and information in a timely manner to the National Emergency Office of the Ministry of Interior and Public Security (ONEMI), the Hydrographic and Oceanographic Service of the Navy (SHOA), and other government authorities. The CSN also makes its data freely available to the scientific world and the community.

The organization maintains and operates 12 seismometer monitoring stations along the San Ramón fault, an active thrust fault which is the main seismic hazard in the Santiago metropolitan area. Station 13 was announced to be operational in August 2017.[10]
