Late Quaternary episodic displacement on a sackung scarp in the central Spanish Pyrenees. Secondary paleoseismic evidence?

Recent advances in landslide investigation: Issues and perspectives

“…Numerically dated gravitational displacement events could be compared with the earthquake catalogues established for the Boconó Fault by historical and paleosimological investigations. If the displacement events on the sackung scarps were demonstrated to be coseismic, then these geomorphic features could be treated as a valuable and complementary source of paleoseismological information (McCalpin and Hart, 2003;Gutiérrez et al, 2008;McCalpin et al, in press).…”

Geomorphological research in Spain

“…In addition to glacial debutressing, fluvial erosion, severe precipitation (Corominas and Moya, 1999), and seismic shaking (e.g. González-Díez et al, 1999;Gutiérrez et al, 2008a;Rosell et al, 2010) are the main natural triggering factors. The occurrence of shallow landslides and debris flows has been largely influenced by changes in land use and land cover (e.g.…”

Deep-seated gravitational slope deformations along the active Boconó Fault in the central portion of the Mérida Andes, western Venezuela

“…monitoring equipment (Bovis, 1990). When triggered or reactivated by earthquakes, they generally evolve in a step-like way, with alternating rather long periods of quiescence and abrupt events of reactivation in connection with seismic shocks (Carton et al, 1987;Bisci and Dramis, 1993;Dramis et al, 1995;Gutiérrez et al, 2008).…”
