Full‐scale Shaking Table Tests on a 10‐story Steel Moment‐resisting Frame Building with Buckling‐restrained Braces

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT In February 2023, a comprehensive series of shaking table tests were conducted at the E‐Defense facility, the world's largest three‐dimensional earthquake simulator, on a full‐scale 10‐story steel moment‐resisting frame supplemented with BRBs.

Petrology of the Basaltic Rocks of the Nankai Trough Basement

, 1993
Major- and trace-element analyses, mineral chemistry, and Sr-Nd isotopic determinations were obtained on representative igneous rocks drilled from the Nankai accretionary complex (Site 808) during Ocean Drilling Program Leg 131. For the first time, the oceanic basement of the subducting plate below an accretionary prism has been reached.

Fault Volume Digital Twin to Reproduce the Full Slip Spectrum, Scaling, and Statistical Laws

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Seismological and geodetic observations of fault zones reveal diverse slip dynamics, scaling, and statistical laws. Existing mechanisms explain some but not all of these behaviors. We show that incorporating an off‐fault damage zone—characterized by distributed fractures surrounding a main fault—can reproduce many key features observed in ...

Depth‐Integrated Boron Inventories of Subducting Oceanic Plates: New Insights From Sediments and Altered Oceanic Crust at ODP Sites 1179, 1173, and DSDP Site 443

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract Boron (B) is a highly fluid‐mobile tracer of slab‐derived fluids in subduction zones; however, the quantitative comparisons of B input among different oceanic plates remain poorly constrained. Here, we present a geochemical study of the sediments, chert, and altered oceanic crust (AOC) from three DSDP/ODP Sites (443, 1173, and 1179 ...

Evidence of strong long-period ground motions of engineering importance for Nankai Trough plate boundary earthquakes: comparison of ground motions of two moderate-magnitude earthquakes

Earth, Planets and Space, 2018
We analyzed strong-motion and broadband recordings of two moderate-magnitude earthquakes that occurred in the Nankai Trough. The first event was the 2004 Mw 6.5 southeast off-Kii peninsula earthquake, an aftershock event inside the Philippine Sea Plate ...

Trophic Relationships Between a Seep Calamyzine Worm and Its Vesicomyid Clam Host Inferred From Multiple Lines of Isotopic Evidence

Marine Ecology, Volume 47, Issue 3, May/June 2026.
ABSTRACT Calamyzine worms are often found in mantle cavities of large chemosymbiotic bivalves in deep‐sea chemosynthesis‐based ecosystems, but the nature of trophic interactions between the worms and their clam hosts remains largely obscure. Here, we combine bulk tissue carbon and nitrogen stable isotope analyses with radiocarbon and nitrogen compound ...

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.

Structural variation in the incoming Philippine Sea plate along the Nankai Trough [PDF]

, 2014
The next large-thrust earthquake along the Nankai Trough, southwest Japan is concerned to occur within this century. Nonvolcanic deep low-frequency tremors and earthquakes are observed around the down-dip limit of the coseismic rupture zone of the last ...

Workshop explores seismogenic zone drilling in the Nankai trough [PDF]

Eos, Transactions American Geophysical Union, 2001
Drilling into the seismogenic zone of an active convergent plate margin and installing a deep borehole observatory in its subduction megathrust are high priorities for the early stages of the new Integrated Ocean Drilling Program (IODP). The Nankai Trough off southwest Japan is one of the most active great earthquake‐generating regions on Earth. Nankai

Characteristics of Seismic Energy Rate Functions of Shallow Tremors

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract We investigated the energy rate functions of shallow tremors southeast of the Kii Peninsula in the Nankai subduction zone. Unimodal functions (triangle or bell‐shaped) explain the characteristics of small (<104 J) shallow tremors. As the seismic radiated energy increases, the energy rate functions become more complex and are better ...
