Journal ArticleDOI
GPS and tectonic evidence for a diffuse plate boundary at the Azores Triple Junction
Fernando O. Marques,Joao P. S. Catalao,Charles DeMets,A.C.G. Costa,A.C.G. Costa,A. Hildenbrand,A. Hildenbrand +6 more
TL;DR: In this paper, the authors use GPS, bathymetric/structural, and seismic data to define the pattern of present deformation along the northern half of the Azores plateau, where the Nubia-Eurasia plate boundary terminates at the axis of the Mid-Atlantic Ridge (MAR).
Reconstructing the architectural evolution of volcanic islands from combined K/Ar, morphologic, tectonic, and magnetic data: the Faial Island example (Azores)
A. Hildenbrand,Fernando O. Marques,A.C.G. Costa,A.L.R. Sibrant,Pedro Silva,B. Henry,Jorge Miguel Miranda,Pedro Madureira +7 more
TL;DR: In this paper, a multi-disciplinary study of the successive stages of development of Faial (Azores) during the last 1 Myr is presented, using high-resolution digital elevation model (DEM), and new K/Ar, tectonic, and magnetic data, in response to complex interactions between volcanic construction and mass wasting, including the development of a graben.

Volcano-tectonic evolution of the Santa Maria Island (Azores): Implications for paleostress evolution at the western Eurasia–Nubia plate boundary
A.L.R. Sibrant,A.L.R. Sibrant,A. Hildenbrand,A. Hildenbrand,Fernando O. Marques,A.C.G. Costa,A.C.G. Costa +6 more
TL;DR: In this paper, the authors presented a comprehensive picture of the volcano-tectonic evolution of Santa Maria, and discussed its significance regarding the stress evolution and regional deformation in the Azores.
Journal ArticleDOI
Large-scale active slump of the southeastern flank of Pico Island, Azores
TL;DR: In this paper, the authors report evidence for ongoing lateral slump of part of the southeastern flank of the Pico volcanic ridge in the Azores, showing that the slumping sector is several cubic kilometers in size and the structure involves several curved scars with normal fault kinematics.
