How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

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 antithetic fault, neither preceded nor followed by the leading fault rupture. The hypocenter of the largest shock (Mw 5....

In the past 20 years, the Corinth Rift Laboratory (CRL) network has been closely monitoring the Western Gulf of Corinth (WGoC), the area being the main focus of the Corinth Rift Near Fault Observatory. The local seismological and geodetic network permitted the detection and location of microseismicity in high resolution, revealing complex sequences...

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 local seismological and geodetic networks for 20 yr. The 2020–2021 seismic crisis evolved in three stages: It sta...

We assess the accuracy and the precision of the TanDEM-X digital elevation model (DEM) of the western Gulf of Corinth, Greece. We use for that a dense set of accurate ground coordinates obtained by kinematic GNSS observations. Between 2001 and 2019, 148 surveys were made, at 1 s sampling rate, along highways, roads and tracks, with a total traveled...

From 2013 to 2015, Etna's surroundings have been covered several times by high tephra fallouts. This behavior expresses a growing new explosive eruptive style of the volcano. In urban areas, the deposits are cleaned between each fallout, which allowed to collect samples very well time-constrained right after each event. However, sampling has systematically been carried out in those urban distal zones (≈ 20 km from the submit), but not directly on the slopes of the volcano. There, deposits are accumulating, forming a thick coat someone who wouldn't have been monitoring attentively the volcano for the last few years could easily assume as the product of one single huge eruption. In this context, we propose to use a cross-domain approach to provide a precise documentation about each layer of this deposit and compare them with the distal samples in order to associate them to each event which gave it birth.
