Centro Sismologico Nacional

The Centro Sismológico Nacional (CSN) of Universidad de Chile is the institution responsible of monitoring the seismic activity in Chile. Our mission is to porvide data and seismological information to the National Emergency Office (Onemi, from its spanish name: Oficina Nacional de Emergencia del Ministerio del Interior y Seguridad Pública), the Servicio Hidrográfico y Oceanográfico de la Armada (SHOA), authorities, cientific community, along with the general public.


The California Strong Motion Instrumentation Program (CSMIP) was established in 1972 by California Legislation to obtain vital earthquake data for the engineering and scientific communities through a statewide network of strong motion instruments. When the planned network is completed, statewide coverage will ensure that strong ground motion for any moderate to larger size earthquake in the state will be recorded.

French Accelerometric Network

Réseau Accélérométrique Français National Data Center (RAP-NDC) provides data and information related to accelerometric data for research activities, technical development or education.



The (IGN) National Geographic Institute was established on September 12, 1870, under the administrative authority of the Statistics of the Ministry of Development, but with full freedom to exercise technical faculties attributed, consisting of "determining the shape and dimensions of the Earth, geodesic triangulations of various orders, precision leveling, triangulation topographic surveying and cadastral map, and determination and preservation of international types of weights and measures. "


The functions that the Institute exercises are, among many others: to elaborate the geological map of Catalonia, in various scales, and carry out mapping software, databases and information systems about soil and subsoil; to develop and maintain the seismic network; to study and assess the geological risks, including earthquake and avalanche risk; to develop and promote work, studies and evaluations in the field of geology and its related sciences; to advise and provide technical assistance in the field of geology and disciplines related to DPTOP, other departments and other administrations


ICIST (Institute for Structure Engineering, Territory and Building Technologies) is a research unit based at IST (Instituto Superior Tecnico), in Lisbon. Through NESS, its Earthquake Engineering and Seismology Group, ICIST is concerned with studies of seismicity, seismic risk and seismotectonics, with emphasis on mainland Portugal and the Azores. In addition, the research goals of NESS include experimental studies of the seismic behaviour of concrete and masonry structures, base isolation systems, etc.


Institute of Engineering Mechanics (IEM), China Earthquake Administration

Indian National Strong Motion Instrumentation Network

The Department of Earthquake Engineering is the only one of its kind in India and amongst a few in the world. Established in 1960 as School of Research and Training in Earthquake Engineering, the department has been actively engaged in teaching, basic and applied research, and providing consultancy services in the seismic design of almost all major engineering projects in the country, with an aim of mitigating disasters caused by earthquakes. These include nuclear power plants, major dams, bridges, petrochemical and other industrial complexes and multistoried buildings.


The Portuguese Sea and Atmosphere Institute, I. P. (IPMA, IP), is a public institution, part of the indirect administration of the State, endowed with administrative and financial autonomy and its own property.

The IPMA I. P., continuing responsibility of the Ministry of Agriculture and Marine, under supervision and guardianship of the respective minister.

The strategic guidelines and setting goals for IPMA, I. P., as well as the monitoring of their implementation, are articulated between members of the Government responsible for the sea and science.


ISMD is the new INGV strong-motion data web portal that provides soon after the earthquake (ML ≥ 3.0) occurrence both waveforms and related metadata.

Soon after the comunication of the event occurrence (UTM origin time, hypocentral coordinates and local magnitude) provided by the Italian National Earthquake Center of INGV, the ISMD automatic system downloads 5 minutes of signals starting from the event origin time.


The Institute of Engineering Seismology & Earthquake Engineering (ITSAK) is a research center established in 1979. It has been operating free field strong motion instruments on a national scale (consisting of more than 96 instruments) and a special 3D strong motion array in the Euro-SeisTest. Moreover, two permanent special arrays on structures are maintained by the staff of ITSAK, those of Evripos cable-stayed bridge and a building at Thessaloniki. 





The NEES@UCSB facility consists of permanently-instrumented geotechnical test sites designed to improve our understanding of the effects of surface geology on strong ground motion. The instrumentation at these sites includes surface and borehole arrays of accelerometers and pore pressure transducers designed to record strong ground motions, excess pore pressure generation and liquefaction that occurs during large earthquakes. An instrumented structure is also monitored to improve our understanding of soil-foundation-structure interaction (SFSI) effects.


NERA-NA3 takes over from the initiative launched by NERIES-NA5 that focused on archiving the continuos accelerometric and broadband waveforms (RRSM db) recorded by high quality seismometer stations in and around Europe.

NIED-Japan Strong-motion Seismograph Networks

 K-NET (Kyoshin network) is a nation-wide strong-motion seismograph network, which consists of more than 1,000 observation stations distributed every 20 km uniformly covering Japan. K-NET has been operated by the National Research Institute for Earth Science and Disaster Prevention (NIED) since June, 1996. At each K-NET station, a seismograph is installed on the ground surface with standardized observation facilities.


The main objective of the National Seismological Service (SSN) is to provide timely information on the occurrence of earthquakes in the country and determine its main parameters such as the magnitude and epicenter. Similarly, the SSN is responsible for providing the necessary information to improve our ability to assess and prevent seismic and volcanic risk at national level


Taiwan Strong Motion Instrumentation Program (TSMIP) started from 1990, and is installed and maintained by CWB


The USGS National Strong-Motion Project (formerly titled the National Strong Motion Program) has the primary Federal responsibility for recording each damaging earthquake in the United States on the ground and in man-made structures in densely urbanized areas to improve public earthquake safety.
