AB - ABSTRACT: The Tauramena Earthquake occurred in Colombia in the eastern border of the North Andes, on the 19 of January of 1995 (ML = 6.5), producing a considerable damage and several life losses. This paper presents the source rupture characteristics of that earthquake, obtained by performing a multitime window linear source inversion, using strong motion short period and teleseismic broadband data. The aftershocks distribution of the earthquake shows two perpendicular fault planes, one corresponding to the mainshock, dipping to the north-west with an inverse fault mechanism, and the second corresponding to a big aftershock. The slip distribution of the mainshock shows the existence of two asperities, that are located on regions of few aftershocks occurrence. The rake angle in the fault plane shows a strong temporal change in orientation for the region corresponding to the main asperity, suggesting a low level of initial shear stress.

AB - ABSTRACT: A study of Paleogene sedimentation and tectonic activity of the Maracaibo Basin, based on the integration of seismics, bio/lithostratigraphy and sedimentology, permitted to gain a better understanding of the development of the basin and to refine the models of the petroleum system. At the end of the Cretaceous, compression between the Nazca plate and South America caused: 1) uplift of the Central Cordillera in Colombia and concomitant formation, east of it, of the Orocue foreland basin, in which Paleocene molasse deposited; and 2) eastward movement of the Caribbean plate. From the Late Paleocene onward, oblique collision of this plate with South America resulted in the emplacement of the Lara Nappe to the northeast of the Maracaibo Basin, causing the development of the Trujillo depocentre which was filled with turbiditic deposits. On the Maracaibo platform, located between the two depocentres, a northeastward prograding clastic system developed. A compressive phase in the Middle Eocene caused the development of the SB44 intra-Eocene unconformity. After 42.5 Ma, an important marine transgression took place. In the western part of the basin, paralic conditions prevailed, whereas in the east deep marine sediments were deposited. During the Oligocene, subsidence continued in the Orocue foreland basin as well as in northeastern Zulia and Falcon, related here to transcurrence along the Oca fault. Finally, the Andean orogeny resulted in inversion and partial erosion of the Paleocene section. Differences between the Maracaibo and Los Llanos basins include the ages of the Mirador, Carbonera and Leon formations (due to backstepping of facies) and the age of the main phase of Paleogene erosion.
