3 SCIENTIFIC DIVISION SEISMIC ENGINEERING HAZARDS EVALUATION GROUP OF INFORMATION STRUCTURAL ANALYSIS EVALUATION OF VULNERABILITY AND SEISMIC RISK PATHOLOGY OF STRUCTURES GEOLOGICAL HAZARDS SEISMICITY, SEISMIC EFFECTS AND SEISMIC HAZARD GEODINAMICAL STUDIES (SEISMOTECTONIC SETTING) (LANDSLIDES, LIQUEFACTION AND RELATIONS WITH HYDROMETEOROLOGICAL FACTORS) LIBRARY

4 Bouger Gravimetrics Anomalies (Carib 97-Smit, Small).

5 Caribbean seismicity

6 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).

13 Rio Carpintero Station

14 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
