Forty-two new focal mechanisms from 50- to 100-km depth beneath the Gibraltar Arc and Alboran Sea show different characteristics. The most abundant solutions are strike-slip mechanisms, in agreement with relative plate motion between Nubia and Eurasia. Additional reverse faulting mechanisms indicate compression in direction of absolute plate motion, reproducing the basal drag of the mantle on the hanging lithosphere. In turn, no signature of ongoing subduction was found. Migrated sections of P wave receiver functions suggest that a significant part of intermediate deep seismicity is produced within the stalled remnants of Jurassic age, oceanic lithosphere that once formed the connection between the Alpine Tethys and the central Atlantic and later has been buried beneath the Gibraltar Arc. 000078942 536__ $$9info:eu-repo/grantAgreement/ES/MINECO-FEDER/CGL2015-67130-C2-2-R 000078942 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000078942 590__ $$a4.497$$b2019 000078942 591__ $$aGEOSCIENCES, MULTIDISCIPLINARY$$b17 / 198 = 0.086$$c2019$$dQ1$$eT1 000078942 592__ $$a2.442$$b2019 000078942 593__ $$aGeophysics$$c2019$$dQ1 000078942 593__ $$aEarth and Planetary Sciences (miscellaneous)$$c2019$$dQ1 000078942 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000078942 700__ $$aFernández-García, C. 000078942 700__ $$aStich, D. 000078942 700__ $$aMancilla, F.D.L. 000078942 700__ $$aMartín, R. 000078942 700__ $$aMolina-Aguilera, A. 000078942 700__ $$aMorales, J. 000078942 7102_ $$12000$$2280$$aUniversidad de Zaragoza$$bDpto.
