Broadband Station Network ROA/UCM/GFZ in South Spain and Northern Africa

Abstract

The seismotectonic importance of the Eurasian-African plate boundary in the western part of the Mediterranean region near the Iberian peninsula has motivated the installation of a new network of broadband and seismographic stations in this area. At present, the network consists of four stations located in San Fernando (Cadiz), SFUC; Cartagena, CART; Mahon (Menorca), MAHO; and Melilla (North Africa), MELI (Figure 1). The first station, SFUC, was installed in 1996 and the rest from 1997 to 1999. There are plans to install a fifth station in Ceuta (North Africa). The stations are run by a joint operation of Real Observatorio de la Armada, San Fernando, Cadiz (ROA); Universidad Complutense, Madrid (UCM); and GeoforschungZentrum, Potsdam, Germany (GFZ). The stations are part of the GEOFON Permanent Network of broadband seismographic stations, and their data can be obtained through the GEOFON Data Center (Hanka and Kind, 1994). The Institute of Geophysics of the ETH in Zurich participated in the operation of the MELI station until December 2001. At every station there are also permanent GPS stations, which have been operating since 1995 in SFUC, 1997 in CART, 1998 in MELI, and 1998 in MAHO (Martin-Davila et al. , 2000). The stations are instrumented with three-component …
