This research explores the effects of erosion-induced isostatic rebound in low convergent mountain ranges, specifically the Pyrenees and Western Alps, highlighting how erosion can lead to extensional strain even in the presence of low horizontal motion.
Mar 11, 2021 · By quantitatively comparing pre- and post-earthquake high-resolution DEMs, we detected denudation depth of the earthquake induced landslides, calculated the total volume of co-seismic landslide and predicted long-term isostatic rebound in response to the landslide unloading.
We then investigate how erosion influences the stress loading of thrust faults using a simple model for the seismic cycle.
Although several geodynamic processes have been proposed to explain this vertical component of movement (post glacial rebound, slab breakoff, crustal overcompensation, ...), we examine the simple hypothesis that the isostatic response to erosion dominates the observed vertical motion.
Here we model the two‐dimensional surface displacement field generated over a full earthquake cycle accounting for coseismic deformation, postseismic relaxation, landslide erosion, and erosioninduced isostatic compensation.
Apr 1, 2013 · Here we show that erosional processes are the predominant control on present-day deformation and seismicity. We demonstrate, using finite element modeling, that erosion induces extension and rock uplift of the elevated region of mountain ranges accommodating relatively low overall convergence.
Jul 1, 1985 · A mountain's history includes two distinctive phases, one of active tectonism and construction followed by one of erosion and passive isostatic rebound. In the first phase uplift is driven by tectonic mechanisms while in the second phase base …
Erosional and constructional shorelines found around the perimeter of Lake Lahontan were prob-ably both the result of storm waves,but they ap-pear to have been formed at different average heights above still water level.
Jul 29, 2013 · Here, P. Vernant and colleagues show that erosion of topography can lead to vertical motions, which in turn can create very low horizontal deformations and earthquakes.
Beneath the elevated part of these mountain ranges, analysis of earthquake focal mechanisms indicates extension, which is commonlyinterpreted as the result of gravitational collapse.
