Consequences of mountain shaking during the 2019-2024 oblique rifting episode at Mount Þorbjörn, Reykjanes Peninsula, Iceland Open
The Reykjanes Peninsula (Iceland) has been experiencing an oblique rifting episode since 2019. Intense and repeated earthquake swarms (magnitude up to ML~5) and ground shaking accompany the deformation of the region. Magma accumulation in …

Forgotten Faults that are Compatible with the Kinematics of the External Hellenides (Greece) Open
Current GNSS data from southwestern Greece indicates an extension rate of 6 mm.yr-1 in the NE-SW direction, i.e., perpendicular to the Hellenic subduction zone. Additionally, there is a significant NW-SE extension component, parallel to th…

Deformation Mechanisms During the Syn‐Orogenic Extrusion of the High‐Pressure Phyllites‐Quartzites Unit in the Central and Northern Peloponnese, Greece Open
The High‐Pressure Phyllites‐Quartzites (PQ) unit of the External Hellenides is exposed in tectonic windows in the central and northern Peloponnese (Greece). Understanding the deformation history of this unit is essential to interpreting th…

Faulting activity during the 2021 oblique rifting event in the Reykjanes Peninsula (SW Iceland) Open
The Reykjanes Peninsula is located at the boundary between the North American and the Eurasian plates. The Peninsula is experiencing an oblique rifting episode that started with a strong earthquake swarm the 24 February 2021, preceded by s…

Surface fractures generated during the 2021 Reykjanes oblique rifting event (SW Iceland) Open
We use a comprehensive dataset of field observations, high spatial resolution drone orthomosaics and digital terrain models (DTMs) to map, quantify and characterize the extensive ground fracturing related to the 2021 seismo-tectonic and vo…

The sprawl of the External Hellenides: from post-Alpine collapse to present-day kinematics Open
During the Neogene, the Aegean domain underwent intense deformation, leading to a thinning by a factor of two or more of the Alpine orogenic prism. Today, tectonic velocity gradients are still among the fastest in Europe due to the Anatoli…

An Atypical Shallow Mw 5.3, 2021 Earthquake in the Western Corinth Rift (Greece) Open
Moderate‐to‐large earthquakes in rifts may occur on leading boundary faults or inner antithetic faults. Here we show a rare case of the 2020–2021 seismic sequence in the Corinth rift, that culminated in the shallow rupture of the antitheti…

Sub-surface fault slip dynamics during the 2021 Reykjanes unrest (Iceland) Open
<p>The dynamics of fault slip in the upper hundreds of meters of Earth&#8217;s crust has long been an open question, as their behavior differs from classical elastic dislocation models and their observation still raises challenge…

Widespread ground cracks generated during the 2021 Reykjanes oblique rifting event (SW Iceland) Open
<p>The Reykjanes Peninsula has recently been subject to a seismo-tectonic unrest triggering widespread ground cracks. This started with a strong seismic swarm from 24 February to 17 March 2021 and culminated in a volcanic eruption on…

The Western Gulf of Corinth (Greece) 2020–2021 Seismic Crisis and Cascading Events: First Results from the Corinth Rift Laboratory Network Open
We investigate a seismic crisis that occurred in the western Gulf of Corinth (Greece) between December 2020 and February 2021. This area is the main focus of the Corinth Rift Laboratory (CRL) network, and has been closely monitored with lo…

Using Kinematic GNSS Data to Assess the Accuracy and Precision of the TanDEM-X DEM Resampled at 1-m Resolution Over the Western Corinth Gulf, Greece Open
We assess the accuracy and the precision of the TanDEM-X digital elevation model (DEM) of the western Gulf of Corinth, Greece. We use a dense set of accurate ground coordinates obtained by kinematic Global Navigation Satellite Systems (GNS…
