The Detection of Transient Subduction Zone Interface Properties Using Teleseismic Data

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The physical properties of subduction zone interfaces govern the transition between stable aseismic slip, episodic slow slip events (SSEs), and large earthquakes. Ultraslow velocity layers (USVLs) along the megathrust are commonly interpreted as indicators of elevated pore‐fluid pressures that promote slow slip, but their temporal variability ...

A Review of Whistler Wave Propagation and Interaction Experiments at Arecibo Observatory, Puerto Rico

Physics
BU–MIT whistler wave injection experiments, which were conducted at Arecibo Observatory, started with the joint US–USSR Active Space Plasma Program Experiment on 24 December 1989. In this experiment, a satellite-borne VLF transmitter injected radio waves

Hydro‐Mechanical Controls on Swarm Recurrence on the Westernmost Gofar Transform Fault, East Pacific Rise

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Swarms are microearthquake clusters governed by aseismic deformation, fluid migration, and stress changes, but the underlying mechanisms for their recurrence remain elusive. In 2008, abundant swarms were observed on the westernmost Gofar transform fault.

Do Eclipse‐Induced Thermospheric TADs Originate From Above or Below?

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Solar eclipses generate significant wave activity in the Earth's upper atmosphere. The source region of eclipse‐induced Traveling Atmospheric Disturbances (TADs) in the upper thermosphere—particularly the relative contributions of gravity waves from the thermosphere itself versus the lower atmosphere—remains unknown. Using the Whole Atmosphere

Sudden Ionospheric Disturbances Generated by Solar Flares—Not so Sudden?

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract It is known that solar flares generate instantaneous ionization enhancement, referred to as sudden ionospheric disturbance (SID), that occurs simultaneously across the entire dayside. In this work, we use high‐rate 1‐s data of total electron content (TEC) to analyse ionospheric response to 13 solar flares that occurred in 2003–2023.

Is the Deep Martian Mantle Heterogeneous? A Reappraisal of Seismological Evidences

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract It has been proposed that the deep Martian mantle contains distributed heterogeneities preserved since the accretion of the planet. This result relies on a multiple‐scattering interpretation of frequency‐dependent arrival times of P $P$‐waves detected in the spectrograms of teleseismic Martian events.

Estimation high-frequency energy radiation of the 2013 Lushan Mw6.6 earthquake by envelope inversion

Abstract This study uses the envelope inversion method to investigate the characteristics of high-frequency energy radiation of the 2013 M w 6.6 Lushan earthquake. We selected near field acceleration records from two small earthquakes as empirical Green’s functions and applied the ...

Revealing the Mechanisms of Heat Extremes Using an AI Enabled Diagnostic Framework

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Heat extremes have become a major health hazard around the world. Understanding their mechanisms remains a major challenge because the physical drivers interact in a nonlinear way. Here we introduce a globally perturbed reforecast framework driven by the Neural general circulation model (NeuralGCM).

Sulfur‐Bearing hcp Iron for Earth's Inner Core

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Earth's iron core is believed to contain light impurities which should have been included during core formation. In order to place constraints on core composition, here we report the effect of sulfur on density of hexagonal close‐packed (hcp) iron which was not previously examined, using laser‐heated diamond anvil cells with in situ ...
