Commissariat à l’énergie atomique et aux energies alternatives - Département analyse, surveillance, environment
The environmental assessment and monitoring Department (Département analyse, surveillance, environment, DASE) from the Commissariat à l’énergie atomique et aux energies alternatives (CEA), developed expertise in monitoring seismic events, detecting radionuclides, measuring atmospheric phenomena and designing sensors and related networks.
The DASE's team is responsible for detecting any seismic event, quickly locating it, calculating its magnitude and issuing an alert to the authorities. To meet their operational duties and anticipate future requirements, the DASE teams conduct fundamental research in earth and environmental sciences : in seismology, fluid-rock interaction, geology, tsunami, electromagnetism, signal processing, geophysic sensors DASE is expert on tsunami warning systems and tsunami modeling. DASE is in charge of the Centre Polynésien de prévention des tsunamis in Tahiti (French Polynesia).
DASE is the Tsunami National contact and the Tsunami warning focal point for France for the Intergovernmental coordination Group of the Pacific tsunami warning system.The French government nominated CEA to coordinate the establishment of the French tsunami warning system and create and operate the CENALT (Centre d’alerte aux tsunamis) that will be operative in 2012, in the framework of the NEAMTWS.The activities on tsunami research are at international and national levels. Since 1993, DASE has participated to various European projects (GITEC, GITEC-TWO, TRANSFER).
