[HTML][HTML] Tectonostratigraphic evolution and significance of the Afar Depression
Abstract The Afar Depression is a unique place on Earth where active rift processes can be
directly observed. It is believed to be close to continental breakup. The Afar hotspot has a …

Strain accommodation by magmatism and faulting as rifting proceeds to breakup: Seismicity of the northern Ethiopian rift
The volcanically active Main Ethiopian rift (MER) marks the transition from continental rifting
in the East African rift to incipient seafloor spreading in Afar. We use new seismicity data to …

Strain accommodation in transitional rifts: Extension by magma intrusion and faulting in Ethiopian rift magmatic segments
Active deformation within the northern part of the Main Ethiopian Rift (MER) occurs within
approximately 60 km-long, 20 km-wide 'magmatic segments' that lie within the 80 km-wide …

Obliquity along plate boundaries
M Philippon, G Corti - Tectonophysics, 2016 - Elsevier
Most of the plate boundaries are activated obliquely with respect to the direction of far field
stresses, as roughly only 8% of the plate boundaries total length shows a very low obliquity …

Structural control on magmatism along divergent and convergent plate boundaries: Overview, model, problems
V Acocella - Earth-Science Reviews, 2014 - Elsevier
Plate boundaries are the most active, unstable and hazardous areas on Earth. The aim of
this study is twofold. 1) Provide an overview of the main structural features along divergent …

Re‐orientation of the extension direction and pure extensional faulting at oblique rift margins: Comparison between the Main Ethiopian Rift and laboratory …
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 of faulting in the …

Formation and stability of magmatic segments in the Main Ethiopian and Afar rifts
As rifting progresses to seafloor spreading, extension within the continental crust commonly
is accommodated by a combination of fault slip and dike intrusion. Consistent patterns in the …
