Kinematic framework along the southern Cuban margin. OFZ- Oriente Fault Zone; WFZ – Walton Fault Zone; EFZ – Enriquillo Fault Zone, SFZ- Swan Fracture Zone; CSC - Cayman Spreading Centre; CCB – Cabo Cruz Basin; SDB – Santiago Deformed Belt; CNF – Cauto Nipe Fault; PF – Pinar Fault; NCFS – Nortecubana

Fault System; SCFS – Surcubana Fault System. The mapped OFZ trace, including CCB and SDB is taken from Calais and Mercier de Lépinay (1990, 1991). The PF and CNF traces are taken from Draper and Barros (1994).

Communications between BB Stations and the Central Station in

Santiago de Cuba

Due to problems with the telephone lines is impossible to transmit the signals in “real time” to the Central Station, them the signals are analyzed at each station and the information of picked amplitude and phases is transmitted by:

• Telephone• Transceiver in HF.• Modem
