Fault‐Controlled Plumbing System Beneath Lipari Volcanic Island Revealed by Seismic Matrix Imaging
Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract Lipari Island hosts an active magmatic–hydrothermal system, but its deep plumbing architecture remains poorly resolved due to strong seismic scattering. We apply passive seismic matrix imaging to public vertical‐component cross‐correlation functions from the dense 2018 Lipari nodal array, recovering relative‐reflectivity structures to ∼10 km ...

The Role of Metamorphic Fluid in Tectonic Tremor Along the Alpine Fault, New Zealand
Geophysical Research Letters, 2021 Abstract The production of H 2 O during metamorphism along active plate boundaries is inferred to contribute to low‐frequency tectonic tremor. This study combines predictions from phase equilibria and mechanical modeling of coincident volume changes to investigate links of ...

Earth, Planets and Space, 2023 Slow slip events (SSEs) lasting for approximately 1 year occur every 6–8 years around the Bungo Channel in the southwest Japan subduction zone. The slip time evolution of the latest Bungo Channel SSE that occurred in 2018–2019 has been studied; however ...

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract We present a new 3D Hikurangi subduction interface model by using an implicit modeling approach that integrates seismic‐reflection profiles, relocated hypocenters, focal mechanism orientations, and tomographic interpretations. The model reveals along‐strike transitions in slow slip events (SSEs) that correlate with subduction interface ...

Tidal sensitivity of tectonic tremors in Nankai and Cascadia subduction zones [PDF]
Journal of Geophysical Research: Solid Earth, 2015 AbstractTectonic tremors in subduction zones, which result from slip at the deep plate interface, are known to exhibit a 12.4 h periodicity in their activity, due to tidal influence. Because tidal stress can be calculated quantitatively, the response of the plate interface can yield quantitative information about its frictional property.

Event Size Distribution of Shallow Tectonic Tremor in the Nankai Trough [PDF]
Geophysical Research Letters, 2019 AbstractSlow earthquake size distributions have been found to follow either a power law or an exponential law, depending on the data set. We investigated the size distribution of shallow tectonic tremor events along the Nankai trough, southwestern Japan, observed in 2009, 2015, 2016, and 2018 and estimated the seismic energy radiated during the events ...

Earth Surface Processes and Landforms, Volume 51, Issue 9, September 2026.Numerical modelling of earthquake‐induced progressive rock slope damage in the paraglacial Serpentine valley, Prince William Sound, Alaska. Repeated seismicity generates rock mass damage that may have conditioned areas of the slope for failure during present‐day ice retreat.

Communications Earth & EnvironmentDeep tectonic tremor occurs repeatedly at the base of a forearc mantle wedge corner, where a highly fluid-pressurized serpentinite shear zone is thought to develop.

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.Abstract We propose a method to infer detailed spatiotemporal variations in interplate coupling by integrating geodetic and seismic data. It examines whether focal mechanisms of intraplate earthquakes occurring near the plate interface align with the stressing rates caused by a geodetically derived slip‐deficit rate model, evaluating deviations from a ...

Source Effects in Higher‐Order Ambient Seismic Field Correlations
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.Abstract Ambient seismic noise interferometry is widely used for surface wave imaging. It typically requires synchronous station recordings and assumes uniform noise source distributions. Higher‐order correlations, such as the re‐correlation of the reconstructed direct waves C2 $\left({C}_{2}\right)$, enable imaging with asynchronous data and can ...
