Global Primary and Secondary Microseism Multi‐Decade Geographic Variation, Secular Intensification, and Period Lengthening

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Earth's long period background seismic wavefield is dominated by two distinct processes that couple ocean wave energy to a global microseism wavefield. We assess global microseism intensity in the secondary (4–10 s) and primary (14–20 s) bands, and across eight 2 s‐wide period bands between 4 and 20 s.

Autocorrelation‐Based Imaging of Crustal Discontinuities Including the Main Himalayan Thrust and Vp/Vs Ratio in the Jammu and Kashmir Himalaya

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract The Jammu and Kashmir Himalaya, located between the rupture zones of the 1905 Kangra and 2005 Kashmir earthquakes, represent a prominent “seismic gap” where understanding the subsurface structure is critical for seismic hazard assessment. This study presents new insights into the crustal structure of this region using teleseismic P‐wave coda ...

Normal Modes in a Coupled Earth Model: A New Perspective on the Compliance Method

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract To understand the compliance parameters observed for atmospheric pressure waves, we develop a normal‐mode approach for a coupled Earth model that includes the atmosphere and the solid Earth. Extending the method of Press and Harkrider to a coupled Earth model, we introduce two new features.

Mantle Dynamic Topography of the Fringing Oceanic Basins of Antarctica

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Dynamic mantle processes are known to influence oceanic basins with implications for ocean circulation and climate. This study exploits an interdisciplinary approach to probe present‐day mantle and lithosphere beneath Antarctica's fringing oceanic basins to better understand sub‐crustal processes and implications for the continental realm.

Measurement of Phase Velocity and Ellipticity of Multi‐Mode Surface Waves by Beamforming Multi‐Component Ambient Seismic Noise

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Conventional beamforming of multi‐component ambient seismic noise typically utilizes only the vertical‐vertical (ZZ) component to extract Rayleigh wave dispersion curves or the transverse‐transverse (TT) component for Love waves. In this study, we extend weighted and modified beamforming to cross‐correlation functions between different ...
