THE WESTERN MEDITERRANEAN (WM) BROAD BAND SEISMIC NETWORK

Abstract

In order to study the seismicity associated to the western part of the Eurasia-Africa plate boundary at the Ibero-Maghrebiam region, ROA in collaboration with UCM and the support of GFZ have deployed, since 1996, a Broad-Band seismic network with stations installed in Southern Spain and Spanish sites in Northern Africa. This network has been expanded with a station in Evora (Universidad de Evora), Portugal, and others in Averroes and Ifrane (Université Mohammed V), Morocco, forming the new Western Mediterranean Network (WM). It’s planned to install, in the near future, four stations, in Tiouin (Morocco), Oran (Algeria) in collaboration with the Université d’Oran, and two more in South Portugal in collaboration with the Evora University. In order to improve the WM network, five Ocean Bottom Seismographs (OBS) will be deployed in the Gulf of Cadiz and Alboran Sea, including a permanent station (OBS ALBORAN) and four (FOMAR net) semi-permanent stations. Deployment of OBS is planned to be carried out on 2007-2008.
