Tide‐Modulated Ocean‐to‐Earth Energy Conversion Quantified With Coastal Fiber Sensing
Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract Quantifying how incident ocean waves transfer energy into seismic surface waves along the nearshore is essential for understanding coastal hazards and Earth–ocean coupling, yet time‐resolved in situ estimates have been scarce. Here we use a beach‐deployed distributed acoustic sensing array co‐located with an ocean‐bottom node to directly ...

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract Snow dampens sounds, but anecdotal reports concisely describe audible propagating collapse events—firnquakes—in Antarctic and Arctic snowfields. We propose combining granular and continuum mechanics to form a testable theory for conditioning, triggering, and propagation of firnquakes consistent with scarce data.

P‐Wave Reverberations in the Water Column of the Chilean Subduction Trench
Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract P‐waves generated by subduction earthquakes can get trapped within the submarine trench, where they reverberate and contaminate the initial seismic signals. We analyze the behavior of P‐wave reverberations for 43 earthquakes of magnitude larger than 6.0 that occurred along the Chilean margin between 1995 and 2023. We compared the energy of the

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract Slow, aseismic fault slip has emerged as a significant contributor to the seismic cycle. However, whether slow and fast slip arise from similar physical processes remains unresolved, due to detection biases affecting noisy surface measurements and the analysis of the source properties of slow slip.

On the Construction of Moho Reflected Shear Wave Phases From Ambient Noise
Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract Shear waves reflected from the Moho (SmS) are frequently identified in ambient noise cross‐correlation functions. Despite their consistent appearance across various arrays and studies, the physical origin and generation mechanisms of these SmS phases remain poorly understood.

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract The origin of a binary‐mixing of DM and EM1 sources for the Cenozoic intraplate volcanism in eastern Northeast China is yet unclear. Seismic attenuation imaging is a tool that can shed light on this question. Here we present the first map of teleseismic P‐wave attenuation across Northeast China.

EURASIP Journal on Advances in Signal ProcessingSuppressing random noise in seismic signals is an important issue in research on processing seismic data. Such data are difficult to interpret because seismic signals usually contain a large amount of random noise.
