Asteroseismology and interferometry of the red giant star epsilon Oph

, 2009
The GIII red giant star epsilon Oph has been found to exhibit several modes of oscillation by the MOST mission. We interpret the observed frequencies of oscillation in terms of theoretical radial p-mode frequencies of stellar models.

Fluid‐Induced Fault Reactivations in Strike‐Slip Regimes: Temporal Constraints From GNSS and Seismological Analysis in the Peloritani Mts and Aeolian Archipelago (Central Mediterranean)

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.
Abstract Fluids can modify the mechanical properties of rocks, including shear strength and strain behavior. We investigate the timing and magnitude of seismic events during fault motion in strike–slip systems across the Peloritani Mountains (northeastern Sicily) and Aeolian Archipelago using GNSS and seismological data analysis.

Evidence and Causes of an Unusual Super Plasma Bubble Occurrence During Weak Geomagnetic Conditions Over Europe

Space Weather, Volume 24, Issue 1, January 2026.
Abstract Using data from a cluster of ground‐based global navigation satellite system, we observed spatially extended enhanced ROTI over the European longitudes during a weak geomagnetic storm (Dst ≈ ${\approx} $ −50 nT) on 4 November 2023. The enhanced ROTI is extended over an extensive geographical latitudinal range of 46°N.

Passive seismic interferometry by multidimensional deconvolution

GEOPHYSICS, 2008
We introduce seismic interferometry of passive data by multidimensional deconvolution (MDD) as an alternative to the crosscorrelation method. Interferometry by MDD has the potential to correct for the effects of source irregularity, assuming the first arrival can be separated from the full response.

Turning standalone seismometers into strainmeters using tidal strain and ambient noise: a feasibility study

Earth, Planets and Space
Solid Earth is subjected to gravitational tidal deformations in the nanostrain order. We focus on detecting seismic shear wave velocity changes caused by this phenomenon.

Study on crustal deformation of Wenchuan Ms8.0 earthquake using wide-swath ScanSAR and MODIS

Geodesy and Geodynamics, 2011
This paper presents a broad-range study of the co-seismic deformation field of Wenchuan Ms8.0 earthquake by ScanSAR interferometry. The results show co-seismic displacements ranging from −19.8 on the footwall side of the seismogenic fault to 73.6 cm on ...

Implications of very long baseline interferometry measurements on North American intra-plate crustal deformation [PDF]

Very Long Baseline Interferometry experiments over the last 1-3/4 years between Owens Valley, CA and Haystack, MA Radio Observatories suggest an upper limit of east-west crustal deformation between the two sites of about 1 cm/yr. In view of the fact that

Nondestructive testing of railway embankments by measuring multi-modal dispersion of surface waves induced by high-speed trains with linear geophone arrays

Seismica
To effectively address engineering challenges and risks, it is crucial to characterize mechanical properties of near-surface environments. The Multichannel Analysis of Surface Waves (MASW) has proven to be a valuable active seismic imaging technique by ...
