Scientific Rationale and Requirements for a Global Seismic Network on Mars [PDF]

open access: yes, 1991
Following a brief overview of the mission concepts for a Mars Global Network Mission as of the time of the workshop, we present the principal scientific objectives to be achieved by a Mars seismic network.

Standing Slow-Mode Waves in Hot Coronal Loops: Observations, Modeling, and Coronal Seismology

open access: yes, 2010
Strongly damped Doppler shift oscillations are observed frequently associated with flarelike events in hot coronal loops. In this paper, a review of the observed properties and the theoretical modeling is presented.

Frictional Behavior of Natural Granite Gouges at Hydrothermal Conditions With Varied Initial Grain Size

open access: yesGeophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract Fine‐grained gouge found in fault cores controls earthquake generation through its frictional behavior and microstructural evolution. Here we present friction experiments on natural granitic gouges of various initial grain sizes at hydrothermal conditions.

Dike Swarms in the Oceanic Lithosphere Beneath the Ontong Java Plateau

open access: yesGeophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract The Ontong Java Plateau (OJP) is believed to have formed through large‐scale Cretaceous volcanism, but the impact of the massive volcanism on the lithosphere remains largely unknown. In this study, the ascent process of the thermochemical plume and its impact on the physicochemical properties of the pre‐existing lithosphere were explored. High‐

The influence of observation environment on background noise level of gPhone gravimeter

open access: yesGeodesy and Geodynamics, 2017
Based on the observations of 36 gPhone gravimeters in 2015, the background noise levels in the seismic frequency band (200–600s) and sub-seismic band (1–6 h) are calculated.

Ice Sheets Without Dynamic Topography

open access: yesGeophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract Dynamic topography results in uplift and subsidence events on Earth's surface with amplitudes on the order of a kilometer. These vertical motions are known to have influenced ice sheet evolution, but how dynamic topography has controlled the current state of present ice sheets is unknown.

Mapping Geothermal Fluids Using Seismic Absorption and Scattering: A Case Study From Aluto Volcano

open access: yesGeophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract Seismic attenuation tomography is used to map fluids and fractures beneath the Aluto volcano geothermal field of the Main Ethiopian Rift. We present 3D models of peak delay (Δlog10Tpd ${\Delta }{\log }_{10}\left({T}_{pd}\right)$) and inverse coda quality factor (Qc−1 ${Q}_{c}^{-1}$) which are proxies for seismic scattering and absorption.

Determination of Transverse Density Structuring from Propagating MHD Waves in the Solar Atmosphere

open access: yes, 2013
We present a Bayesian seismology inversion technique for propagating magnetohydrodynamic (MHD) transverse waves observed in coronal waveguides. The technique uses theoretical predictions for the spatial damping of propagating kink waves in transversely ...
