Kinematic Representations of Viscoelastic Postseismic Deformation
Earth and Space Science, Volume 12, Issue 8, August 2025.Abstract Following large earthquakes, viscoelastic stress relaxation may contribute to postseismic deformation observed at Earth's surface. Mechanical representations of viscoelastic deformation require a constitutive relationship for the lower crust/upper mantle material where stresses are diffused and, for non‐linear rheologies, knowledge of absolute

Towards an analytical theory of the third-body problem for highly elliptical orbits
, 2016 When dealing with satellites orbiting a central body on a highly elliptical orbit, it is necessary to consider the effect of gravitational perturbations due to external bodies. Indeed, these perturbations can become very important as soon as the altitude

GeoHealth, Volume 9, Issue 8, August 2025.Abstract Highly pathogenic avian influenza (HPAI) virus presents a serious threat to poultry and public health worldwide, with transmission dynamics shaped by avian migration patterns and environmental conditions. Recent outbreaks in the Philippines highlight the urgent need for effective control measures.

Waveform Effects on Shear Wave Splitting Near Fault Zones
Journal of Geophysical Research: Solid Earth, Volume 130, Issue 8, August 2025.Abstract Shear wave splitting of teleseismic core phases such as SKS is commonly used to constrain mantle seismic anisotropy, a proxy for convective deformation. In plate boundaries, sharp lateral variations of splitting measurements near transform faults are often linked to deformation within a lithospheric shear zone below, but potential seismic ...

Space Weather, Volume 23, Issue 8, August 2025.Abstract We present observations of plasma structuring from three meters up to hundreds of kilometers at auroral latitudes during the extreme geomagnetic storm of May 2024 using co‐ordinated observations from ICEBEAR and Global Navigation Satellite Systems (GNSS) receivers. Intense irregularities on all spatial scales co‐existed for about 4 hr between ∼
