Benefits of GNSS Local Observations Compared to Global Weather‐Based Models for InSAR Tropospheric Corrections Over Tropical Volcanoes: Case Studies of Piton De La Fournaise and Merapi

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 4, April 2025.
Abstract From repeat‐pass interferometry, tropospheric signals often prevent the detection of ground deformation signals. In recent years, tropospheric corrections derived from global weather‐based models have been implemented in several InSAR processing chains.

The Transition From Jointing to Faulting Observed at the Koa'e Fault Zone, Hawai'i Volcanoes National Park, Hawaii

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 4, April 2025.
Abstract Fractures can exhibit mixed modes of displacement, that is, combinations of displacements parallel and perpendicular to the fracture plane, that make a displacement‐to‐length (Dmax/L) scaling analysis challenging. However, such analysis is important for understanding the propagation and nature of mixed‐mode fracture populations. In this study,

Modeling Wavelength Dependent Mid‐Infrared (5.5–25 μm) Optical Constants of Silicate Glasses: A Genetic Algorithm Approach

open access: yesEarth and Space Science, 2023
Wavelength‐dependent mid‐infrared (400–1,800 cm−1; 5.56–25 μm) optical constants (real and imaginary indices of refraction; n and k) are determined using reflectance spectra at a spectral sampling of 4 cm−1 for several silicate glasses of varying SiO2 wt%

Inferring Eruption Dynamics From Seismometer Tilt: A Case Study of Erebus and Augustine Volcanoes

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 4, April 2025.
Abstract Broadband seismometers are sensitive to tilt as a consequence of their design. We used broadband data from Erebus volcano on Ross Island, Antarctica, and Augustine volcano in Lower Cook Inlet, Alaska, to make tilt measurements associated with individual volcanic explosions and investigate the near‐terminal magmatic system configuration of each

Identifying Landslides in Atla Regio on Venus

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 4, April 2025.
Abstract We performed a systematic search for landslides in the Alta Regio region of Venus, located from (16°S, 179°W) to (21°N, 147°W). Using data primarily from Magellan Cycle 1 radar imagery, we identified 29 landslides in this region. There were 19 previously identified across the entire surface (Malin, 1992, https://doi.org/10.1029/92je01343 ...

Fine‐Scale Crustal Velocity Structure at the Lucky Strike Segment of Mid‐Atlantic Ridge From Full Waveform Inversion of Wide‐Angle Seismic Data

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 3, March 2025.
Abstract The Lucky Strike segment at the Mid‐Atlantic ridge, characterized by a well‐defined median valley with a central volcano, is an archetypical slow‐spreading ridge segment and hence an ideal site for studying magmatic and tectonic processes at slow‐spreading ridges.
