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.

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract We investigate the spatiotemporal evolution of foreshocks preceding the 2025 Mw 8.8 Kamchatka earthquake by applying single‐station analysis to waveforms recorded at the nearest seismic station. Our results reveal a southwestward migration of foreshocks toward the mainshock epicenter through multiple stages, with a migration speed of ∼7.0 km ...

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 ...

The Depositional Record, Volume 12, Issue 2, April 2026.During the Late Permian, the rise of the Gondwanides Belt trapped marine waters, giving birth to a vast megalake. This lake shifted between overfilled, balanced‐fill and underfilled stages that are recorded by high‐frequency accommodation changes, while meteorological seiches shaped the sedimentary dynamic and produced heterolithic beds.

Damping Modification Factors for Pile–Induced Filtering Effect
Earthquake Engineering &Structural Dynamics, Volume 55, Issue 4, Page 907-925, 10 April 2026.ABSTRACT Period–dependent Damping Modification Factors are usually applied to the 5%–damped pseudo–acceleration response spectrum at free field conditions to derive the seismic demand for structures with damping ratio other than 5%. Likewise, the response spectrum at the foundation level of pile–supported structures may differ from the free field ...

Scour‐Conditioned Seismic Fragility Analysis of Monopile‐Supported Offshore Wind Turbines
Earthquake Engineering &Structural Dynamics, Volume 55, Issue 4, Page 947-967, 10 April 2026.ABSTRACT Monopile‐supported offshore wind turbines (MS‐OWTs) are increasingly deployed in seismic coastal regions, where they face compound risks from earthquake loading and seabed scour. While past studies have addressed these hazards separately, seismic fragility under evolving scour conditions remains insufficiently understood. This study introduces
