The recording and analysis of seismic waves enables researchers to understand Earth’s dynamics and to improve knowledge of seismic hazards.
EOST is in charge of permanent seismic stations located in northeastern France and abroad (Senegal, French Austral and Antarctic Territories). They are integrated into national (e.g. RLBP, RAP) and international (GEOSCOPE) networks.
EOST is the national coordinator of the French Broadband Seismic Network (RLBP), the French Central Seismological Office (BCSF) and the National Network of Seismic Surveillance (RéNaSS). These last two produce the national bulletin of earthquakes occurring in France. BCSF also collects and analyses macroseismic observations (earthquake effects) to asses EMS98 intensity.
