ABSTRACT

Recent geodynamics of the Sierra-Maestra is determined by crustal compressive stresses as a result of the opening of Bartlett's deep-sea trench and the underthrusting of its left side beneath the edge of th e Cuban plate. In this process there is a general uplift, transverse and oblique splitting into separate blocks. Five major transverse blocks are distinguished: Wes­tern (300-500 m), Central ( 1500-2000 m), and Eastern (800-1 000 m) Sierra Maestra, the zone of plains and plateaus Santiago-Boniato and Sierra Grand-Piedra (800-1200 m) whose traces can also be discerned in transverse differentiation of Bartlett's trench and the Kauto­~uacanayabo depression. Major seismically active knots are at intersections of longitudinal and transverse morphostructures. The largest (K = 10-13) and deepest (50-70, less often 100-120 km) earthquakes .and the maximum epicentre density are in the underthrust zone. Earthquakes on land have shallow foci (mostly 5-25 km) and much smaller magnitudes. Particularly great activity is exhibited by the superposed depress ion of Santiago-de-Cuba, where a multi-purpose geodynamic polygon is being created.
