Key Parameters for the Ionospheric Detection of Tsunamis From the 29 July 2025 Kamchatka Event

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract It has been demonstrated that tsunamis generate internal gravity waves (GWs) detectable in the ionosphere within 20–60 min after their generation at the ocean surface. Despite numerous simulation and observation studies on ionospheric signatures of tsunamis, the detection of Co‐tsunamic Ionospheric Disturbances (CTIDs) and distinguishing them ...

Effects of Bulk Poroelasticity on Repeating Earthquake Sequences: Insights From Numerical Modeling

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract At seismogenic depths, faults and the surrounding rock are saturated with water. Fault slip induces volumetric strains in the bulk, causing compression or dilation of pore fluid, which alters pore pressure—a phenomenon known as the poroelastic effect. This pore pressure change can, in turn, influence fault slip behavior.

A Global Centroid Catalog of S‐Wave Microseisms: Insights Into the Role of Sedimentary Layers

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract Although centroid catalogs of P‐wave microseisms have been established, a corresponding centroid catalog of S‐wave sources has been lacking. In this study, we constructed a centroid catalog of S‐wave microseisms. We generalized the autofocusing method to radial and transverse components to estimate the source locations of SV‐ and SH‐wave ...

How Large Are Marsquakes? Revisiting Magnitude Scaling and Implications for Marsquakes and Meteoroid Impacts

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Reliable estimates of seismic source size on Mars are critical for interpreting tectonic activity and impact processes, constraining the planet's interior evolution, and informing the design of future Martian seismic experiments. However, because InSight observations are limited to a single station, magnitude estimates cannot rely on empirical

Automatic Extraction of a Generalized Physics‐Based Feature From Time‐Lapse Active Source Ultrasonic Waveforms for Prediction of Shear Stress in Laboratory Friction Experiments

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Physics‐based handcrafted features, such as P‐wave amplitude derived from early parts of active source ultrasonic waveforms, successfully predict shear stress evolution. This study investigates whether feature extraction can be automated by leveraging full active source ultrasonic waveforms recorded during a laboratory friction experiment.
