Activity and vp/vs ratio of volcano-tectonic seismic swarm zones at nevado del ruiz volcano, colombia
(UNIVERSIDAD NACIONAL DE COLOMBIA, 2010)
An analysis of the seismic activity for volcano-tectonic earthquake (VT) swarms zones at Nevado del Ruiz Volcano (NRV) was carried out for the interval 1985- 2002, which is the most seismic active period at NRV until now ...
The Oligocene-Neogene deep-sea Columbia Channel system in the South Brazilian Basin: Seismic stratigraphy and environmental changes
(ELSEVIER SCIENCE BV, 2009)
The Columbia Channel (CCS) system is a depositional system located in the South Brazilian Basin, south of the Vitoria-Trindade volcanic chain. It lies in a WNW-ESE direction on the continental rise and abyssal plain, at a ...
Sediment deformation in Miocene and post-Miocene strata, Northeastern Brazil: Evidence for paleoseismicity in a passive margin
(ELSEVIER SCIENCE BV, 2011)
Stratigraphic intervals characterized by varied and complex styles of soft-sediment deformation structures are well preserved in Miocene and Late Pleistocene to Holocene deposits of a sedimentary basin located in Northeastern ...
Regionalización morfoestructural de la Sierra Maestra y de las depresiones circundantes
(1986)
El análisis detallado de las morfoestructuras de Cuba Sudoriental permitió elaborar el presente esquema de regionalización morfoestructural, con el objetivo fundamental de determinar las unidades morfoestructurales más ...
Upper-mantle seismic structure beneath SE and Central Brazil from P- and S-wave regional traveltime tomography
(WILEY-BLACKWELL PUBLISHING, INC, 2011)
We present models for the upper-mantle velocity structure beneath SE and Central Brazil using independent tomographic inversions of P- and S-wave relative arrival-time residuals (including core phases) from teleseismic ...
Revisiting the North Chile seismic gap segmentation using GPS-derived interseismic coupling
(Oxford University Press on behalf of The Royal Astronomical Society, 2013)
No major earthquake occurred in North Chile since the 1877Mw 8.6 subduction earthquake that
produced a huge tsunami. However, geodetic measurements conducted over the last decade in
this area show that the upper plate ...
Evidences of seismic events during the sedimentation of Sete Lagoas Formation (Bambui Group - Ediacaran, Brazil)
(Elsevier B.V., 2020-03-01)
The Sete Lagoas Formation (Ediacaran), located in the central part of the Sao Francisco Craton (Brazil), consists of limestones and dolostones deposited in very shallow waters in the inner part of the carbonate platform. ...
Late Quaternary sedimentation in the Paraiba Basin, Northeastern Brazil: Landform, sea level and tectonics in Eastern South America passive margin
(ELSEVIER SCIENCE BV, 2011)
Late Quaternary deposits in the northeastern Brazil have been scarcely investigated, despite their relevance to the discussion of the post-rift evolution of the South American passive margin within the context of landform, ...
