The Centro Sismológico Nacional (CSN), previously called Servicio Sismológico de Chile, is a seismological organization within the Faculty of Physical and Mathematical Sciences (FCFM) of the University of Chile.[1][2] The current director is Sergio Barrientos.[3]

Research

The organization delivers seismic information to the National Office of Emergency of Chile (ONEMI) and to the Hydrographic and Oceanographic Service of the Chilean Navy (SHOA).[1] Through the use of 65 seismological stations, the organization monitors and conducts seismological research and monitoring.[4]

In the Global Seismographic Network (GSN) it is known by the acronym GUC, which stands for "Geophysics University of Chile".

History

Conceived by University director Valentín Letelier, the Service was founded by Chile's President, Pedro Montt, on May 1st, 1908, to meet the need for a seismological organization in the country after the earthquake that struck Valparaíso in 1906.[5]

The first director of CSN was Fernand de Montessus de Ballore. The first seismological station run by the service was installed in 1908 on the Santa Lucía Hill in Santiago. Later stations were constructed in Tacna, Copiapó, Osorno and Punta Arenas, amongst others.[2] Recent historical investigations revealed that the Service created a network of four second-tier observatories and a central observatory between 1908 and 1909, and 29 seismic stations in 1909. The system also collected testimonies of observers including telegraphers, lighthouse guardians, railway workers and volunteers.[6]

In 2013, it was renamed Centro Sismológico Nacional.
