The Northern Apennines (NA) hinterland area is characterized by a complex Neogene‐Quaternary tectonics where both crustal extension, associated with the Tyrrhenian Basin opening, and shortening in onshore took part deformation. Analysis of synorogenic deposits preserved NNW trending Siena‐Radicofani (SRB), extending along large NA hinterland, documents evolution deformation this sector during last 9 Ma. Information from subsurface geology (deep seismic lines, commercial deep wells), surface...
Abstract In this study, we draw on a unique combination of well‐resolved fault‐slip data and earthquake focal mechanisms to constrain spatial variations in style faulting the obliquely extending Main Ethiopian Rift, East Africa. These show that both boundary internal faults – oblique orthogonal plate divergence (PD) respectively exhibit almost pure dip‐slip motion, indicate significant local deflection orientation extension direction at rift margins. Scaled analogue models closely replicate...
The Main Ethiopian Rift (MER) is a narrow continental rift characterized by an along‐axis variation in evolution, with early stages the south evolving to incipient breakup north. Although distribution and style of Quaternary volcanotectonic deformation well known northern sector, knowledge these characteristics comparatively less constrained southward. In this paper we present results field structural study carried out better constrain time‐space faulting central sector MER (central MER)....
Abstract Continental rift systems form by propagation of isolated segments that interact, and eventually evolve into continuous zones deformation. This process impacts many aspects rifting including morphology at breakup, eventual ocean-ridge segmentation. Yet, segment growth interaction remain enigmatic. Here we present geological data from the poorly documented Ririba (South Ethiopia) reveals how two major sectors East African rift, Kenyan Ethiopian rifts, interact. We show formed...
Up to recently the Neogene‐Quaternary evolution of northern Apennines (Italy) has been described by classic model a migrating eastward, compressive external front, with an extensional regime in back areas connected Tyrrhenian basin formation. However, last few years, new structural data have collected internal marine and continental episutural basins, exposed thrust belt. A complex now reconstructed, coeval main tectonic phases that affect both stress field change. Four identified since Late...
Abstract Southern Ethiopia is a key region to understand the evolution of East African rift system, since it area interaction between main Ethiopian (MER) and Kenyan rift. However, geological data constraining in this remote are still relatively sparse. In study timing, distribution, style rifting southern constrained by new structural, geochronological, geomorphological data. The border faults roughly parallel preexisting basement fabrics progressively more oblique with respect regional...
In the Main Ethiopian Rift (East Africa) a complex tectonic history preceded Tertiary rifting creating pre-existing discontinuities that influenced extension-related deformation. Therefore, this area offers opportunity to analyze control exerted by structures on continental at different scales. paper we present an overview of such influence. We show large scale (up ∼800–1,000 km) rift localization has been controlled lithospheric-scale inherited heterogeneity corresponding Precambrian suture...
Magmatism in extensional tectonic settings, such as the East African Rift System, is mainly modulated by interaction of plume upwelling and plate dynamics, resulting complex processes associated to rifting (e.g., rift migration, focusing) generating a large compositional variability erupted products, even over small distances short time periods. The Ririba rift, formed from southward propagation Main Ethiopian Rift, well exemplifies these complexities providing unique opportunity investigate...
In recent years, new approaches for developing earthquake rupture forecasts (ERFs) have been proposed to be used as an input probabilistic seismic hazard assessment (PSHA). Zone- based with seismicity rates derived from catalogs are commonly in many countries the standard national models. Italy, a single zone- ERF is currently basis official model. this contribution, we present eleven ERFs, including five zone-based, two smoothed seismicity-based, fault- based, and geodetic-based, PSH model...
We present an analysis of the distribution, timing, and characteristics volcano‐tectonic activity on western margin Southern Main Ethiopian Rift in Soddo area (latitudes between ~7°10'N ~6°30'N). The is characterized by presence numerous normal faults, with limited vertical offset often sigmoidal shape, which accommodate a gentle transition from rift floor to plateau. New radiocarbon dating indicates post‐30 ka fault activity, pointing significant Late Pleistocene‐Holocene tectonic margin....
Abstract The Afar region in East Africa represents a key location to study continental breakup. We present an integrated structural analysis of the Western Margin (WAM) aiming better understand rifted margin development and role plate rotation during rifting. New information from remote sensing, fieldwork, earthquake data sets reveals that N‐S striking WAM is still actively deforming characterized by NNW‐SSE normal faulting as well series marginal grabens. Seismicity distribution first‐ever...
Abstract We provide insights into the tectonics of Asela‐Langano margin, at eastern boundary central Main Ethiopian Rift, East Africa, by combining field structural data, remote sensing, analysis distribution faults, new dating faulted material, and seismicity. The area is characterized occurrence two fault sets: axial (Wonji) oriented NE‐SW NNE‐SSW, respectively. Boundary faults show a complex arrangement in lake Langano where they display rhomboidal pattern, due to presence NW‐SE‐trending...
