Decadal Stability of Multi‐Scale Core‐Mantle Boundary in Core‐Reflections of Repeating Earthquakes

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Temporal changes near the core‐mantle boundary (CMB) would trigger insights into ongoing thermal and chemical interactions between the Earth's core and mantle. Here, we search for multidecadal temporal changes in the CMB topography and heterogeneity using waveform similarity analysis of core‐reflected phases (PcP, ScP, and ScS) from global ...

A Deep Learning Approach for the Automated Classification of Geomagnetically Induced Current Scalograms

Applied Sciences
During geomagnetic storms, which are a result of solar wind’s interaction with the Earth’s magnetosphere, geomagnetically induced currents (GICs) begin to flow in the long, high-voltage electrical networks on the Earth’s surface.

Vulnerability Assessment of Korean Electric Power Systems to Late-Time (E3) High-Altitude Electromagnetic Pulses

Energies, 2019
High-altitude electromagnetic pulses (HEMPs) are bursts of electromagnetic energy that result from nuclear weapon detonations at altitudes at or above 30 km. A HEMP is comprised of three components: E1, E2, and E3.

Enabling High‐Fidelity Wave‐Particle Interaction Studies: A Novel Filtering for Isolating Whistlers From Spacecraft Noise

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Resolving the mixture of natural plasma waves and persistent spacecraft interference is a fundamental challenge in space physics, as it obstructs the analysis of wave‐particle interactions and energy transport processes. Traditional signal decomposition methods often fail to adequately separate these components due to their time‐varying ...

A Curie Point Depth Model of the Conterminous United States Derived From a Prior‐Constrained Equivalent Source Inversion

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract The Curie Point Depth (CPD) is a key thermal boundary in the deep lithosphere and is widely used to constrain its thermal structure. However, uncertainties in magnetization and the non‐uniqueness of inversion lead to considerable inter‐study differences.

The Geomagnetically Induced Current Extremal Values Estimation Based on Baygazan Magnetical Station Data

Russian Journal of Earth Sciences
Based on the Baygazan magnetic station data, geomagnetically induced currents (GIC) in the 500 kV Sayano-Shushenskaya HPP (SSHPP) – Novokuznetsk substation power line were simulated during very strong and extreme magnetic storms (planetary geomagnetic ...

Surface Air Enrichment of Cosmogenic 35S at a Subtropical Site During the May 2024 Solar Superstorm

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Cosmogenic radiosulfur (35S) is produced in the atmosphere by high‐energy particle interactions and serves as a sensitive tracer of stratospheric intrusions. In May 2024, an extreme solar storm provided a rare opportunity to examine atmospheric 35S responses to intense solar activity.

Improvement in the modelling of geomagnetically induced currents in Southern Africa [PDF]

, 2016
One of the consequences of the geomagnetic storms resulting from adverse space weather is the induction of geomagnetically induced currents (GICs) in power lines. The GICs that flow in a power transmission network are driven by the induced electric field
