CRUSTAL MOVEMENTS ALONG THE NW HELLENIC VOLCANIC ARC FROM DGPS MEASUREMENTS

Bulletin of the Geological Society of Greece, 2017
The north-western part of the Hellenic Volcanic Arc was studied by Differential GPS measurements in an attempt to investigate the regional deformation of the area. The GPS network involving stations in Athens, Aegina Island, Methana Peninsula and Soussaki was established in February 2006 and since then it was reoccupied twice. The GPS measurements were

Dynamic Evolution of Forearc Subsidence Controlled by Slab Geometry

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Several subduction zones worldwide present an enigmatic forearc topography and strain characterized by extension at a forearc ridge near the trench and shortening within a forearc valley located between the ridge and the magmatic arc. The development of this topography has been linked to progressive slab steepening, while strain patterns ...

Block Kinematics, Interseismic Coupling and Fault Slip Rates in the Aegean Region From GPS and Earthquake Slip Vector Data: 2. Hellenic Subduction System

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract The Hellenic subduction system is the primary locus of Nubia‐Eurasia convergence, yet the distribution of strain accumulation along it is still debated. Here, we invert 832 geodetic velocities and 146 earthquake slip vectors to assess the spatial variability of interseismic locking and provide new constraints on the rate of slip deficit ...

Origin, Tectonic Processes, and Metasomatism of Serpentinite in the Shimanto Accretionary Complex, SW Japan: Possible Diapiric Intrusion of Serpentinized Oceanic Lithosphere

Tectonics, Volume 45, Issue 7, July 2026.
Abstract Serpentinite plays a major role in the geodynamics of subduction zones. However, the processes by which serpentinite is incorporated into accretionary complexes, and the extent to which it interacts chemically and physically with accretionary lithologies, remain unclear.

Sequential Wedge Extrusion to Core Complex Extension: The Central Cycladic Detachment System on Syros, Greece

Tectonics, Volume 45, Issue 7, July 2026.
Abstract Syros island preserves pristine high‐pressure metamorphic rocks and provides invaluable insight into subduction zone processes. Contrasting views on the structural history impede placing the island in a clear tectonic framework, limiting the broader impact of preserved information.

Impact of Fluid Flow on Bacterial Carbon and Sulfur Cycling, Mineral Precipitation, and Transformation in Hydrothermal Sediments off the Coast of Milos

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 7, July 2026.
Abstract Hydrothermal fluid flow not only shapes mineral deposition on the ocean floor but also creates ecological niches by altering temperature and energy availability. In these niches, microbial life thrives and has an additional, often unrecognized impact on mineral formation. In a newly discovered vent field at water depths of 100–200 m off Milos,

Backarc tectonism, volcanism, and mass wasting shape seafloor morphology in the Santorini-Christiana-Amorgos region of the Hellenic Volcanic Arc

Tectonophysics, 2017
Abstract In subduction zone backarcs, extensional deformation and arc volcanism interact and these processes, together with mass wasting, shape the seafloor morphology. We present a new bathymetric map of the Santorini-Christiana-Amorgos backarc region of the Hellenic subduction zone by merging high-resolution multibeam swath data from the R/V ...

Metagenomic investigation of the geologically unique Hellenic Volcanic Arc reveals a distinctive ecosystem with unexpected physiology.

Environmental microbiology, 2016
Hydrothermal vents represent a deep, hot, aphotic biosphere where chemosynthetic primary producers, fuelled by chemicals from Earth's subsurface, form the basis of life. In this study, we examined microbial mats from two distinct volcanic sites within the Hellenic Volcanic Arc (HVA).
