Secegsa, the Spanish Society for Fixed Communication Studies through the Strait of Gibraltar, is conducting a seismic research campaign to explore the feasibility of constructing a tunnel between Spain and Morocco. To support this research, Secegsa has issued a tender for the lease, with an option to purchase, of four ocean bottom seismometers (OBS). These instruments will be used by the Geophysics Department of the Royal Observatory of the Spanish Navy (ROA) for a six-month research campaign, valued at €487,872. In 2010, ROA and Secegsa established a partnership to study seismic activity in the Strait of Gibraltar and its surrounding areas. Since then, they have collaborated to maintain a short-term seismic network in the Strait and analyze the resulting data. In January 2014, three offshore seismic instruments were deployed along an east-west transect at the bottom of the Strait of Gibraltar. These instruments were recovered in September 2014, and new ones have since been deployed to continue the research. Additionally, temporary seismic stations were set up on both sides of the Strait, and a permanent station was established in Ceuta. The study revealed that seismic activity in the Strait region is minimal.
