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 ...

Suppressing Coda Events with a Bayesian Model of Global Scale Seismology
Pure and Applied GeophysicsLarge seismic events often trigger a wave train of slow decaying energy known as the coda that can mislead signal detectors into forming coda detections that appear to look like regular phase detections.

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 ...

Fault activity studies in the Lower Tagus valley and Lisbon region using geophysical data [PDF]
, 2018 he Metropolitan Area of Lisbon and the Lower Tagus Valley (LTV) region are located in central Portugal and inhabited by nearly 4 million people. The region has suffered throughout its history the effect of destructive earthquakes caused by hidden faults,

MHD Waves and Coronal Seismology: an overview of recent results
, 2012 Recent observations have revealed that MHD waves and oscillations are ubiquitous in the solar atmosphere, with a wide range of periods. We give a brief review of some aspects of MHD waves and coronal seismology which have recently been the focus of ...

Environmetrics, Volume 37, Issue 3, April 2026.ABSTRACT On April 6, 2009, central Italy was hit by a Mw6.1$$ {M}_w\kern0.3em 6.1 $$ earthquake that caused 308 victims in the city and province of L'Aquila; subsequently, in 2016, two Mw6+$$ {M}_w\kern0.3em 6+ $$ shocks were recorded in an area located a few dozen kilometers further north, respectively in Amatrice and Norcia.

Spectral-Element and Adjoint Methods in Seismology [PDF]
, 2008 We provide an introduction to the use of the spectral-element method (SEM) in seismology. Following a brief review of the basic equations that govern seismic wave propagation, we discuss in some detail how these equations may be solved numerically based ...

Near Surface Geophysics, Volume 24, Issue 2, Page 110-127, April 2026.Abstract As global groundwater levels continue to decline rapidly, there is a growing need for advanced techniques to monitor and manage aquifers effectively. This study focuses on validating a numerical model using seismic data from a small‐scale experimental setup designed to estimate water volume in a porous reservoir.

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.Abstract Landslides in the European Alps are a growing concern in the context of climate change. However, landslide catalogs for the European Alps remain incomplete, often lacking precise timing and containing few, if any, entries for remote areas.
