The European-Mediterranean Seismological Centre is a non profit organisation with 84 institutes as members from 55 different countries. It has been established in 1975, at the request of the European Seismological Commission. Given that the European-Mediterranean region is prone to destructive earthquakes, there was a need for a scientific organisation to be in charge of the determination, as quickly as possible, of the characteristics of such earthquakes. Therefore, the EMSC receives seismological data from more than 65 national seismological agencies, mostly in the Euro-Med region. The EMSC became operational on 1 January 1975, at the Institut de Physique du Globe de Strasbourg. It received its final statutes in 1983. In 1987, EMSC was appointed by the Council of Europe as the organisation to provide the European Alert System under the Open Partial Agreement on Major Hazards. In 1993, EMSC statutes and organisation were amended. Its headquarters moved to the Laboratoire de Détection et de Géophysique within the Département Analyse, Surveillance, Environnement of the French Atomic Energy Commission, in Bruyères-le-Châtel. As an international, non-governmental and non-profit organisation, this association focuses also on promoting seismological research. This turns into EMSC participation in many European projects: FP7 projects:
Establish and operate a system for rapid determination of the European and Mediterranean earthquake epicentres. EMSC, acting as the central authority, is responsible for transmitting these results immediately to the appropriate international authorities and to the members in order to meet the needs of protection of society, scientific progress and general information.
Determine the main source parameters of major seismic events located within the European-Mediterranean region and dispatch widely the corresponding results.
Encourage scientific cooperation among European and Mediterranean countries in the field of earthquake research, and to develop studies of general interest such as: epicentre location methods, construction of local and regional travel-time tables, magnitude determination, etc.
Promote seismological data exchange between laboratories in the European-Mediterranean area.
Improve the observational systems in the European-Mediterranean region through a critical examination of the seismological coverage, and suggest methods in order to improve the quality of observations and their transmission to EMSC.
Specific approaches
Flashsourcing
EMSC has developed a new approach based on internet traffic analysis: when an earthquake occurs, witnesses rush on EMSC website to look for further explanation of the event. Therefore, they create a surge in the website traffic which can indicate that an earthquake just occurred, even before receiving data provided by national seismological institutes. By identifying the geographical origin of the website's visitors, the area where the earthquake was felt is mapped within a couple of minutes of its occurrence. This technique is named flashsourcing.
Citizen seismology
Citizens are a primary source of information in the real-time earthquake detections. EMSC involves them in earthquake response by collecting in-situ information on the earthquake impact directly from the witnesses. Consequently, these developments provide rapid constraints on the earthquake impact by involving the citizens in the response and draw an efficient way to raise seismic risk awareness.
