| Zusammenfassung |
| The CENALT (CENtre d’ALerte aux Tsunamis) is responsible for the French NTWC (National Tsunami Warning Centre). Its objective is to transmit a message in less than fifteen minutes for any earthquake that could trigger a tsunami in the Western Mediterranean Sea and the North-East Atlantic Ocean. The data collected from French installations and from institutions from five European countries are processed with software that permit to make an early location of the seismic events and to measure the expected sea level effect on the shore. The on-duty analysts interactively revise all the information produced and use references based on historical tsunami and earthquake databases as well as computed tsunami scenario to be able to send the more comprehensive message possible. Communication tests are performed monthly to test and validate the different transmission mode latencies (Global telecommunication system, email and fax). In November 2012, CENALT have participated to the international NEAMWave12 tsunami exercise organized by the Intergovernmental Oceanographic Commission (Unesco/IOC). A scenario of a magnitude 7.5 earthquake located on the north Algerian margin was modeled , and messages were disseminated to the tsunami warning focal points of the Member states of the Mediterranean region. |
