Detection of deep low-frequency earthquakes in the Nankai subduction zone over 11 years using a matched filter technique

Earth, Planets and Space, 2020
To improve our understanding of the long-term behavior of low-frequency earthquakes (LFEs) along the tremor belt of the Nankai subduction zone, we applied a matched filter technique to continuous seismic data recorded by a dense and highly sensitive ...

Broadband Records of Earthquakes in Deep Gold Mines and a Comparison with Results from SAFOD, California [PDF]

, 2009
For one week during September 2007, we deployed a temporary network of field recorders and accelerometers at four sites within two deep, seismically active mines.

Deep Quake Dynamics: A Multimodal Fault‐Aware Approach to Earthquake Magnitude and Occurrence Time Forecasting

Geoscience Data Journal, Volume 13, Issue 2, April 2026.
EQMT integrates earthquake catalog data, fault‐network geometry, engineered features, and graph embeddings in a unified framework for forecasting earthquake magnitude and occurrence time. The framework is designed to reflect inter‐fault spatial dependencies together with temporal seismic patterns, addressing limitations of approaches based only on ...

Detection of Shallow Tectonic Tremors in Hyuga‐nada, Nankai Trough, Using the Newly Established N‐Net OBS Network

Geophysical Research Letters
Monitoring tectonic tremors is crucial for understanding stress release in subduction zones and assessing megathrust earthquake risk. The Hyuga‐nada region, at the western edge of the Nankai Trough, Japan, provides a natural laboratory for investigating ...

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.

Epidote Records (De)hydration From the Seafloor Through Subduction and Underplating: Implications for Subduction Zone Fluid Budgets and Slow Slip

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.
Abstract When, where, and how much fluid is released from subducting oceanic crust control deformation, element cycling, and magmatism in subduction zones. However, the palimpsest of tectonometamorphic processes in the exhumed rock record complicates the relation of geologic observations to geodynamic models of subduction fluid sources and transport ...

Event‐Feature‐Based Clustering Reveals Continuous Distribution of Tectonic Tremors of 0.3–100 s: Application to Western Japan

Geophysical Research Letters
We develop a methodology to compile an objective tremor catalog by utilizing distinctive event features that differentiate tectonic tremors from non‐tremor events, and combining the envelope cross‐correlation method with clustering technique and neural ...

Imaging different components of a tectonic tremor sequence in southwestern Japan using an automatic statistical detection and location method

, 2018
In this study, we demonstrate the capability of an automatic network-based detection and location method to extract and analyse different components of tectonic tremor activity by analysing a 9-day energetic tectonic tremor sequence occurring at the ...

Structure of the North‐Central Chile Subduction Zone From Local Earthquake Tomography

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract The fluid cycle in subduction zones prescribes large parts of its structure and seismogenic behavior. Background seismicity inside the downgoing slab is linked to fluid release from dehydration reactions, whereas fluid overpressure along the plate interface can alter interplate coupling, megathrust earthquakes, and the presence or absence of ...

Tectonic tremor characterized by principal-component analysis in the vicinity of central Chile and Argentina

Journal of South American Earth Sciences, 2019
No conclusive evidence has been presented to date for tectonic tremor (TT) in the vicinity of central Chile, where the Nazca Plate is subducting beneath the South American Plate. Subduction in our experimental location (roughly 35.5° S, 70.5° W) is steep
