  • basins
  • Our kinematic and structural data allow us to confirm the interpretation that the Santa Barbara Basin is the precursor of the Upper Valdarno Basin and that both basins developed in structural depressions formed by the interplay between normal and transfer faults, framed in the extensional tectonics which characterizes Tuscany since Miocene.

  • The tectonic forces that have shaped the surface of Venus have raised only 5 percent of the surface into 'continental masses' and left only 15 to 20 percent of it as basins. (bibliotecapleyades.net)
  • shallow
  • This superposition of deep tectonic contraction within the basement and shallow gravitational extension deformation within the sediment highlights the key role of gas hydrate on outer slope erosion.In addition to long-term regional basal erosion, the margin basement has thinned locally by an extra 0.8-1 km in response to the subduction of the Atacames seamount chain and hydrofracturing by overpressured fluids at the margin toe.

  • The NE (Arkenu 1) and the SW (Arkenu 2) structures have approximate diameters of about 10 km and consist of two shallow depressions with inner low hills surrounded by curved ridges and silica-impregnated cone sheets cut by local faults. (wiley.com)
  • faults
  • Previous interpretations placed active strike-slip faults as close as 55 km from the northern coast of Puerto Rico, which would have implied a greater seismic hazard to Puerto Rico. (noaa.gov)
  • large
  • This result supports previous studies proposing that subducted seamounts provide unfavorable conditions for locking the updip segment of the plate boundary limiting the updip extent of seismogenic zones, but may favor large subduction earthquakes at greater depths. (univ-montp2.fr)
  • pattern
  • During cruises Antithesis 1 and 3 (2013-2016), we recorded the first deep multichannel seismic images and new multibeam data in the northern Lesser Antilles margin segment in order to shed a new light on the structure and tectonic pattern of the Anegada Passage. (univ-montp2.fr)
  • plates
  • The tectonic plates might be beginning to shift," said Karen Davis, the president of the Commonwealth Fund, a nonprofit research group in New York. (nytimes.com)
  • events
  • In such a morphostructural setting, prolonged time intervals characterized by sediment bypass alternated with tectonic events, during which the opening of fractures and fault-related depressions and the generation of slide scars provided suitable settings for trapping and preserving sediments.

  • This observation also argues for the occurrence of previous events during the Quaternary. (scielo.org.ar)
