Ups and downs in western Crete (Hellenic subduction zone)
Studies of past sea-level markers are commonly used to unveil the tectonic history and seismic behavior of subduction zones. We present new evidence on vertical motions of the Hellenic subduction zone as resulting from a suite of Late Pleistocene - Holocene shorelines in western Crete (Greece). Shoreline ages obtained by AMS radiocarbon dating of seashells, together with the reappraisal of shor...
متن کاملInversion of gravity data with application to density modeling of the Hellenic subduction zone
Acknowledgments I would like to thank Prof Dr Uwe Casten for his support, understanding, patience and for his effort put in corrections of this thesis. I especially thank my family and parents. Without them nothing would be possible. I thank all my friends for helping me, supporting me and distracting me, when I was working on my thesis.
متن کاملEfficient gravity data inversion for 3D topography of a contact surface with application to the Hellenic subduction zone
We develop the theoretical foundations, numerical algorithms and computer programs to retrieve the 3D geometry of a density interface from gridded gravity data. The solution depends on constraining assumptions on permissible density values. An integral equation is solved by a new method of local corrections to find the density interface. The method is efficient and does not require trial-and-er...
متن کاملOn the duration of seismic motion incident onto the Valley of Mexico for subduction zone earthquakes
S U M M A R Y We have used finite difference simulations in 2-D models of the lithosphere to estimate the duration of long-period (>2 s) ground motion incident onto the Valley of Mexico for subduction zone earthquakes. Our simulations suggest that two heterogeneous structures extend the duration of the ground motion between the subduction zone and Mexico City by more than 1 min: (1) the Mexican...
متن کاملConstraints on Subduction Geodynamics from Seismic Anisotropy
[1] Much progress has been made over the past several decades in delineating the structure of subducting slabs, but several key aspects of their dynamics remain poorly constrained. Major unsolved problems in subduction geodynamics include those related to mantle wedge viscosity and rheology, slab hydration and dehydration, mechanical coupling between slabs and the ambient mantle, the geometry o...
