This study investigates the present-day seismotectonic framework of High Atlas Mountains, Morocco, with a specific focus on area affected by devastating Mw 6.8 Al Haouz earthquake September 8, 2023. Leveraging high-resolution seismic dataset encompassing over twenty moderate earthquakes (M 3.5-6.8) recorded regional networks between 2008 and 2024, research aims to refine locations characterize stress field. Initially located using P-wave arrival times, hypocenters were subsequently relocated...
In this study, we used the P-wave receiver functions (PRFs) to investigate crustal structure of northern Morocco, located at westernmost edge Mediterranean, near boundary between African and Eurasian tectonic plates. This region is an integral part complex deformation system associated with Alpine orogeny, characterized by concurrent compressional extensional processes. These dynamics have led development various structural models aimed explaining area‘s geological evolution. The...
The Altiplano-Puna plateau, in Central Andes, is the second-largest continental plateau on Earth, extending between 22° and 27°S at an average altitude of 4400 m. Puna has been formed consequence subduction oceanic Nazca Plate beneath South American plate, which crustal thickness 50 km this location. A large seismicity cluster, Jujuy observed depth 150–250 central region plateau. cluster seismically very active, with hundreds earthquakes reported a peak magnitude MW 6.6 25th August 2006....
Understanding the mechanisms of crustal deformation along convergent margins is critical to identifying seismogenic structures and assessing earthquake hazards for nearby urban centers. In southern central Andes (28-33[Formula: see text]S), differences in style middle upper-crustal associated seismicity are highlighted by January 19th, 2021 (Mw 6.5) San Juan earthquake. We integrate waveforms recorded at regional teleseismic distances with co-seismic displacements calculated from local...
Abstract Uplift in the broken Andean foreland of Argentine Santa Bárbara System (SBS) is associated with contractional reactivation basement anisotropies, similar to those reported from thick-skinned Cretaceous-Eocene Laramide province North America. Fault scarps, deformed Quaternary deposits and landforms, disrupted drainage patterns, medium-sized earthquakes within SBS suggest that movement along these structures may be a recurring phenomenon, yet defined repeat intervals rupture lengths....
After a severe M W 5.7 earthquake on October 17, 2015 in El Galpon the province of Salta NW Argentina, I installed local seismological network around estimated epicenter. The covered an area characterized by inherited Cretaceous normal faults and neotectonic with unknown recurrence intervals, some which may have been reactivated faults. 13 three-component seismic stations recorded data continuously for 15 months. The took place Santa Barbara System Andean foreland, at about 17km depth....
The use of Nodal systems based on autonomous geophone-based instruments entered the field Seismology only recently. These lightweight solutions revolutionized seismological fieldwork through and wholistic that are faster to deploy easier handle. IGU-16HR series SmartSolo® is one example, but yet lacking a thorough lab-based performance analysis. Here, we fill knowledge gap, by performing lab field-based tests focus sensors performance. investigated parameters transfer function, self-noise...
The 2023 Mw 6.9 Al Haouz Earthquake in the Moroccan High Atlas mountains is most recent example of a destructive event an intraplate setting under absence causative plate boundary. Their large inter-event times such seismotectonic regimes hinders study single focus regions and apparently underestimates their larger seismic hazard potential, leaving local communities unaware scale exposure to these risks. One major shortcoming immediate scientific analysis this unprecedented earthquake lack...
The Andean foreland is divided into morphotectonic provinces characterized by diverse deformation styles and seismogenic behavior partially stemming from distinct geological histories that preceded the current phase of subduction. transition between high Andes eastern exposed to numerous natural hazards contains critical economic infrastructure, yet we know relatively little about regional active tectonics due few geophysical investigations. Here use waveforms collected during a...
Abstract Gravitational mass wasting prediction requires understanding of the factors controlling failure. Prior to slope failure, cracks in weakened rock are thought grow and coalesce, eventually forming a continuous failure plane. Here, we apply hidden Markov machine learning model seismic data, revealing temporal evolution prior major rockslide event Swiss Alps. After prolonged linear increase crack cumulative number, an S-shaped rate pattern occurred day before rockslide. A simple...
Historical and instrumental seismicity records from the Central Andes of north-western Argentina spanning last ca. 350 years have been primary data source to characterize this region’s exposure seismic hazard as “moderate” “high” (0.18-0.25 PGA). Despite relevance existing dataset in assessments (SHA), we propose that lack detailed neotectonic paleoseismological studies regarding widespread evidence Quaternary seismogenic deformation has...
<p>In order to reduce the societal impact of mass-wasting events, we need observations investigate factors that control slope failure, such as state crack propagation along a failure plane. However, usually plane is not accessible in-situ. Hence, cracks have be monitored indirectly, for example using seismic methods.</p><p>We analysed data from seismometer array in Illgraben catchment, Switzerland, had registered series and leading main event...
