Spatial Interactions Govern Tectonic Tremor Activities in the Nankai Trough: A Statistical Approach for Spatiotemporal Pattern Modeling and Anomaly Detection

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract Establishing a quantitative framework to evaluate the spatiotemporal patterns of slow earthquakes and to detect their anomalous activities is essential for understanding diverse slip behaviors on plate boundaries and seismic hazard assessment. In this study, we focus on deep tectonic tremors, which are one manifestation of slow earthquakes and

GPS constraints on 34 slow slip events within the Cascadia subduction zone, 1997–2005 [PDF]

, 2008
Refinements to GPS analyses in which we factor geodetic time series to better estimate both reference frames and transient deformation resolve 34 slow slip events located throughout the Cascadia subduction zone from 1997 through 2005. Timing of transient

Contrasting Decollement and Prism Properties over the Sumatra 2004-2005 Earthquake Rupture Boundary [PDF]

, 2010
Styles of subduction zone deformation and earthquake rupture dynamics are strongly linked, jointly influencing hazard potential. Seismic reflection profiles across the trench west of Sumatra, Indonesia, show differences across the boundary between the ...

Geodetic Evidence of Time‐Dependent Viscoelastic Interseismic Deformation Driven by Megathrust Locking in the Southwest Japan Subduction Zone

Geophysical Research Letters, 2020
The time‐variable features of interseismic deformation in subduction zones are poorly understood and commonly ignored. Here, by incorporating century‐long leveling data and contemporary global navigation satellite systems (GNSS) velocities, we ...

Prevalence of mud diapirs in the Hyuga-nada subduction zone, southwest Japan, and its implications on hydrogeological processes

Progress in Earth and Planetary Science
Mud volcanoes, common seafloor features in subduction zone forearcs, provide crucial insights into deep hydrogeological systems associated with plate subduction.

Detection of slow slip event lasting several months in the shallow region of the Suruga Trough, the eastern end of the Nankai Trough, Japan

Progress in Earth and Planetary Science
Numerous deep short-term slow slip events (S-SSEs) and long-term slow slip events (L-SSEs) have been detected in the Nankai Trough subduction zone in southwestern Japan based on Global Navigation Satellite System (GNSS) data.

Slip parameters on major thrusts at a convergent plate boundary: regional heterogeneity of potential slip distance at the shallow portion of the subducting plate

Earth, Planets and Space, 2018
Understanding variations of slip distance along major thrust systems at convergent margins is an important issue for evaluation of near-trench slip and the potential generation of large tsunamis.

Time-dependent modeling of slow-slip events along the Nankai Trough subduction zone, Japan, within the 2018–2023 period

Earth, Planets and Space
According to a 2013 report by the Earthquake Research Committee of Japan, it was estimated that the probability of the occurrence of the next Nankai earthquake within the next three decades is 70–80%.
