AB: The European-Mediterranean Seismological Centre (EMSC) has been running for several years an operational alert system for potentially damaging earthquakes which occur in the European-Mediterranean region. This alert system, - sub-part of the EMSC real time information service available on the web site (www.emsc-csem.org) - is based on parametric data provided through the Internet by 40 different networks representing 800 stations in the Euro.-Med. region. In case of potentially damaging earthquake, the seismologist on duty connects to EMSC facilities, merges and processes all available data and, as soon as a reliable solution is available, disseminates alert messages by fax and email. Alert messages are sent by fax to official organisations (e.g., Civil Protection Agency, rescue teams, Council of Europe, ECHO, etc.), to the seismological community and to the public by emails (800 emails). Furthermore, data and results are made automatically available in real time on the web. In case of technical problems or maintenance activities, the duty is taken over by IGN (Madrid, Spain), which runs full back-up procedures. EMSC commits itself to a maximum dissemination time (time lag between the occurrence of the earthquake and the messages' dissemination) of 1 hour. This delay is respected in the vast majority of cases with a median dissemination time of less than 40 minutes. We will give an overview of this system and its performances and put a special emphasis on the processing of the recent earthquake in Algeria.
