The RIFSIS wide-angle reflection experiment through the Rif Cordillera (N Morocco)

In October 2011, we acquired a 330 km-long and a 430 km-long wide-angle seismic reflection profiles oriented, approximately, EW and NS. Each of the 5 sources consisted of 1Tn of chemical explosives in 2 boreholes and was recorded by 845 digital seismographs with one-component 4.5 Hz geophones (Reftek RF125 IRIS-PASSCAL Texans). The average receiver spacing was 750 m. Shots R1 through R3 where located along the NS line, and R3–R5 were along the EW line. Shot R3 is at the intersection of the two profiles. All shots were recorded by all the stations producing fan shots for 3-D control on deep structure. Up to 402 seismographs were deployed along the EW profile and 443 along the NS profile including 35 in Spain. T
