Imaging the Alpine Collision With Seismic Radial Anisotropy

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The Alpine region and the adjacent Northern Apennines (NA) and Northern Dinarides record the complex tectonic evolution associated with the collision between the Eurasian and Adriatic plates. We combine Rayleigh and Love surface waves from ambient noise and earthquake data recorded at over 3,300 seismic stations to construct a high‐resolution ...

Statistical Scale Analyses of a Diurnal Periodicity in Auroral Kilometric Radiation, Observed by Wind/WAVES

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract The Earth's strongest natural radio emission is Auroral Kilometric Radiation (AKR), which is correlated with auroral intensity, and is a barometer for space weather. AKR is generated by the electron cyclotron maser instability, with sources on auroral field lines. Previous work on AKR and radio emissions from other planets (or stars) points to

ABUNDANCES OF N - CAPTURE ELEMENTS IN STARS OF THIN AND THICK DISKS.

Odessa Astronomical Publications, 2007
Abundances of neutron-capture (n- capture) elements in the stars belonging to thin and thick disks are obtained. The separation of thin and thick stars on kinematic criterion was made early. The spectra were obtained with the ELODIE spectrograph at the 1.

MASER: A Science Ready Toolbox for Low Frequency Radio Astronomy

Data Science Journal, 2020
MASER (Measurements, Analysis, and Simulation of Emission in the Radio range) is a comprehensive infrastructure dedicated to time-dependent low frequency radio astronomy (up to about 50 MHz). The main radio sources observed in this spectral range are the

Present‐Day Kinematics of Continental Greece and Balkans Revealed by Sentinel‐1 InSAR Data

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The Balkan Peninsula hosts the highest seismic activity in Europe, marked by numerous Mw6+ earthquakes in diverse tectonic settings. Assessing tectonic surface deformation is crucial to understand the forces controlling kinematics and, ultimately, constraining geodynamic models. However, because measuring slow velocity rates (a few mm/yr) with

Characterizing the Forearc Basement and Subducting Structures of the Northern Ecuadorian Margin

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract We present 2D P‐wave velocity (Vp) models from the northern Ecuadorian subduction zone, north of the Carnegie Ridge. Data were collected during the HIPER2 3D wide‐angle seismic experiment, both onshore and offshore. Key seismic profiles were manually picked to determine P‐wave first‐arrival times, which were used for a traveltime tomographic ...

Vers une meilleure intégration des Observatoires Photographiques du Paysage (OPP) dans la gouvernance territoriale : de l’OPP des experts à l’OPP des habitants ?

Belgeo, 2015
Since 2000, many landscape photographic observatories (Observatoire Photographique du Paysage, OPP) have spread out in France and all around Europe, either at local, regional and national levels.
