Persistent termini of 2004- and 2005-like ruptures of the Sunda megathrust [PDF]

, 2012
To gain insight into the longevity of subduction zone segmentation, we use coral microatolls to examine an 1100-year record of large earthquakes across the boundary of the great 2004 and 2005 Sunda megathrust ruptures.

On the Application of 1 Versus 2 State Variable Rate‐and‐State Friction Laws: An Example From the Nankai Trough Megasplay Fault Zone

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Frictional slip behavior in fault zones can be analyzed with friction laws using 1 or 2 state variables, but the physical meaning and applicability of the 2‐state variable form of the law remain unclear. Here, we re‐analyze friction experiments by Roesner et al. (2022, https://doi.org/10.1186/s40623‐022‐01728‐w) using a natural sample from the

Splay fault branching from the Hikurangi subduction shear zone: Implications for slow slip and fluid flow [PDF]

, 2016
Pre-stack depth migration data across the Hikurangi margin, East Coast of the North Island, New Zealand, are used to derive subducting slab geometry, upper crustal structure and seismic velocities resolved to ∼14 km depth.

Spatiotemporal Variations in the Interplate Slip Rate Around Kodiak Island, Alaska

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Monitoring spatiotemporal variations in the interplate slip rate during the interseismic period, such as transient strain release by slow slip events (SSEs), is crucial for characterizing the physical properties of faults. We analyze 10 years of Global Navigation Satellite System (GNSS) data in the region of Kodiak Island, Alaska.

Structural Evolution of the Eastern Nankai Trough accretionary prism, Central Japan—Subduction of Trough-Parallel Seamount Chains

Progress in Earth and Planetary Science
The Nankai Trough, offshore of Southwest Japan, represents a plate subduction zone where a long history of devastating mega-earthquake and tsunami events has been best documented.

Modeling the Probability of Tsunami Fire Ignition Based on Data From the 2011 Tohoku and 2024 Noto Peninsula Earthquakes, With Recommendations to Reduce Emerging Fire Risk in Tsunami Vertical Evacuation Structures

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 5, Page 1116-1133, 25 April 2026.
ABSTRACT Recent tsunamigenic earthquakes in Japan have highlighted the emerging fire hazard triggered by tsunami inundation and its impact on tsunami vertical evacuation (TVE) structures. This new type of fire following earthquake, referred to as “tsunami fires,” may be a potential universal hazard that tsunami‐prone countries face; however, it has not

Long-term slow slip events along the Nankai trough subduction zone after the 2011 Tohoku earthquake in Japan

Earth, Planets and Space, 2017
The global navigation satellite system (GNSS) network in Japan has detected transient crustal deformation in regions along the Nankai trough subduction zone in southwest Japan from approximately 2013, after the 2011 Tohoku earthquake. Using the GNSS data,

Frictional and hydrologic properties of a major splay fault system, Nankai subduction zone [PDF]

Geophysical Research Letters, 2009
We report on laboratory experiments examining the frictional and hydrologic properties of fault gouge and wall rock along a borehole transect that crosses a major out‐of‐sequence thrust splay fault within the Nankai accretionary complex. At 25 MPa effective normal stress, the fault zone material is frictionally weak (μ ≤ 0.44) and exhibits low ...

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 ...
