TerraceM application to drowned marine terraces in Central Chile

Thursday 25 July 2019 kl. 07:11

Submarine or drowned marine terraces may provide crucial information about deformation rates in areas that usually lack of surface deformation rate estimates. Here we present a recent study of drowned marine terraces in the Arauco Bay and the nearby Santa Maria island, an area that includes the Santa Maria fault system, a structure characterized by surface ruptures and associated coastal uplift during the 2010 Maule earthaquake (Mw 8.8). In this work we used the depth patterns of marine terraces and elastic dislocation models to estimate the slip rate of the Santa Maria Fault and their earthquake recurrence at glacial cycle time-scales.

 

Studying rasa surfaces and marine terraces in slow uplifting coasts, Western Europe.

Wednesday 25 July 2018 kl. 07:51

The Cotentin Peninsula (Normandy, France) displays sequences of marine terraces and rasas, the latter being wide Late Cenozoic coastal erosion surfaces, that are typical of the slow uplifting Western European coasts in Portugal, Spain, France and southern England. Here we use TerraceM to map rasa surfaces ad determine the spatial distribution of marine terraces, reconstruct the paleogeographic coastal morphology of this area, and evaluate along strike variations in vertical deformation and potentially active structures.

TerraceM application at Konya, Turkey

Thursday 19 May 2016 kl. 17:59

Fixed cliff analysis in Konya, Turkey. This is a TerraceM method for shoreline angle calculation in terraces covered by calcrete or beach rock (A) exposing the free face along continious outcrops in the Lake Konya, Turkey (B). (C) The soreline angle is located at the intersection between two linear interpolations on the paleo- platform and one point defining the free face. Field measurements of the free face slope using inclinometer are requiered to calibrate the interpolations (D).
