Geological record of prehistoric tsunamis in Mugi town, facing the Nankai Trough, western Japan

Progress in Earth and Planetary Science, 2019
Stratigraphic and paleontological investigations in Mugi Town, on the Pacific coast of Shikoku Island, revealed evidence of as many as five tsunami inundations from events along the Nankai Trough between 5581 and 3640 cal yr BP.

Long-term slow slip events along the Nankai trough delayed by the 2016 Kumamoto earthquake, Japan

Earth, Planets and Space, 2020
The Global Navigation Satellite System network in Japan detected transient crustal deformation along the Nankai trough, Japan, from June 2018. Time-dependent inversion analysis shows that a long-term slow slip event in northern Hyuga-nada Sea along the ...

Mechanical Weakness of the Nankai Accretionary Prism: Insights From Vp Measurements of Drill Cuttings

Geochemistry, Geophysics, Geosystems, 2021
The relationship between P‐wave velocity (Vp) and unconfined compressive strength (C0) can be used to estimate in situ rock strength and stresses at depth in subduction zones.

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.

Simulation of great earthquakes along the Nankai Trough: reproduction of event history, slip areas of the Showa Tonankai and Nankai earthquakes, heterogeneous slip-deficit rates, and long-term slow slip events

Earth, Planets and Space, 2022
Great earthquakes have occurred repeatedly along the Nankai Trough, but only for recent events are details known, such as rupture areas and time lags between paired events.

Estimate of the contraction rate of central Japan through the deformation of the Philippine Sea slab

Progress in Earth and Planetary Science, 2019
The Philippine Sea (PHS) slab is severely deformed beneath central Japan, but it is subject to little deformation before the subduction along the Nankai Trough.

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

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 10, Page 2356-2378, August 2026.
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.

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.

Longitudinal Molecular Epidemiology and Genomic Surveillance of Carbapenem‐Resistant Klebsiella pneumoniae in the Gut of Healthy Individuals in China

MedComm, Volume 7, Issue 8, August 2026.
Using 16,040 stool samples from healthy individuals across 30 Chinese provinces (2016–2024), we performed longitudinal genomic surveillance of carbapenem‑resistant Klebsiella pneumoniae (CRKP) colonizing the gut. We reveal rising community CRKP prevalence, especially in southern China, a shift from blaKPC‐2 to plasmid‑borne blaNDM‐5 on IncHI2/IncHI2A ...

Seismic Characteristics of the Gas Hydrate System in the Mackenzie Trough of the Canadian Beaufort Sea, Arctic Ocean

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract We present a comprehensive seismic characterization of the gas hydrate system in the outer continental shelf of the Mackenzie Trough, Canadian Beaufort Sea, based on recently acquired multichannel seismic (MCS) data, P‐wave velocity modeling, and 3D thermal modeling. We identified high‐amplitude, reverse‐polarity Bottom‐Simulating Reflections (
