Tectonic Inversion and Geomorphic Evolution of the Algerian Margin Since Messinian Times: Insights From New Onshore/Offshore Analog Modeling Experiments

“…Onshore, recent and active reverse faults have been evidenced by the deformation of Quaternary sedimentary units (Authemayou et al, 2017;Boudiaf, 1996;Boudiaf et al, 1999) and earthquake data (Ousadou & Bezzeghoud, 2019). Two main north-dipping reverse faults are identified in the coastal domain.…”

On the long-lasting sequences of coral reef terraces from SE Sulawesi (Indonesia): Distribution, formation, and global significance

“…Eustasy-corrected uplift rates are given by dividing the difference between the present elevation of the shoreline angle and the eustatic sea level at its formation time by the age of the terrace (Lajoie, 1986). We compute, for reference, apparent uplift rates (Table 3) that neglect any a priori eustatic correction (as in Pedoja et al, 2011Pedoja et al, , 2014Yildirim et al, 2013;Authemayou et al, 2016).…”

The large Algerian earthquakes (267 A.D.-2017)

“…Major earthquakes could generate the uplift of the coastline as observed significantly during the Boumerdes earthquake with an average of 0.5 m. The gradual uplift has been also demonstrated in the marine terraces of the Sahel anticline in the region of Algiers Authemayou et al, 2016). The implementation of the Geodetic network of Algeria with presently 56 stations and very soon with more than hundreds of stations will allow to precise the convergence pattern proposed by Yelles-Chaouche et al(2009c) …”
