Potential Bias in Inferred Megathrust Slip Rates Induced by the Neglect of Material Heterogeneity

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Accurate knowledge of the pattern of interseismic coupling on megathrusts is critical to preparing for future earthquakes and tsunamis. However, published models for a given fault zone commonly differ widely, making hazard assessment difficult.

Plate Divergence at the Krafla Volcanic System, Iceland: Insight From GNSS Geodesy and Sentinel‐1 Satellite Radar Interferometry in 2002–2024

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract The Krafla volcanic system in Iceland, a subaerial segment of the divergent boundary between the North American and Eurasian plates, offers a unique opportunity to investigate volcano‐tectonic processes. We present a six‐segment kinematic back slip plate boundary model constrained jointly by long‐term deformation velocity fields from Global ...

Retrieval of body waves with seismic interferometry of vehicle traffic: A case study from upstate New York, USA

Seismica
Seismic interferometry of vehicle traffic recorded by a vertical seismograph array along a highway in upstate New York has recovered surface and body waves that match the velocities of waves in the Devonian and Silurian shales. Faster arrivals extracted

Steam caps in geothermal reservoirs can be monitored using seismic noise interferometry

Communications Earth & Environment, 2023
Harvesting geothermal energy often leads to a pressure drop in reservoirs, decreasing their profitability and promoting the formation of steam caps. While steam caps are valuable energy resources, they also alter the reservoir thermodynamics.

Linking Interseismic Locking to Coseismic Rupture: The 2025 Mw 8.8 Kamchatka Earthquake

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract We investigate interseismic locking on the Kamchatka megathrust, source of the 2025 Mw 8.8 earthquake, using a data‐driven probabilistic framework. Horizontal GNSS velocities constrain a boundary element model on a triangulated megathrust geometry, while an algorithmic sampling strategy estimates the locking probability for fault elements ...

Interaction of Air Pressure and Groundwater as Main Cause of Sub‐Daily Relative Seismic Velocity Changes

Geophysical Research Letters, 2023
Our study investigates variations of seismic velocity that occur over short time scales of hours. We use coda wave interferometry to inspect 5 months of continuous data from a seismological array in southern Germany.

The 2025 Mw 7.6 Aomori Megathrust Earthquake in Northeast Japan: Failure of a Structurally and Rheologically Bounded Asperity Beneath a Cold Mantle Wedge

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract To explore mechanisms of rupture segmentation, we invert coseismic GNSS offsets for the 2025 Mw 7.6 Aomori, Japan earthquake. Our preferred curved‐fault solution images a compact thrust rupture at 25–50 km depth with peak slip ∼2.5 m near 35 km.

Seismic interferometry for in-mine exploration

, 2022
Im Zuge des Forschungsprojektes "Seismic Imaging Techniques for Mineral Exploration" wurde die Anwendung von passiver seismischer Interferometrie (PSI) in untertägigen Strecken und dessen Eignung für die Mineralexploration getestet. Zu Validierungszecken wurde PSI mit der 3D-Bohrlochradartechnologie und einer aktiven seismischen Messung verglichen. Die

Tectonic Tremor Reveals Slow Deformation Along the Antarctic–South American Subduction Zone

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The Antarctic–South American subduction zone is among the least explored convergent margins and lacks documented large interplate earthquakes despite ongoing convergence. Here we report the discovery of tectonic tremor along this plate boundary using continuous seismic data.

Temporal Changes of Seismic Velocity Caused by Volcanic Activity at Mt. Etna Revealed by the Autocorrelation of Ambient Seismic Noise

Frontiers in Earth Science, 2019
On active volcanoes, ambient noise-based seismic interferometry can be a very useful monitoring tool as it allows to detect very slight variations in seismic velocity associated with magma transported toward the surface.
