Laboratory observations of slow earthquakes and the spectrum of tectonic fault slip modes [PDF]
, 2016 Slow earthquakes represent an important conundrum in earthquake physics. While regular earthquakes are catastrophic events with rupture velocities governed by elastic wave speed, the processes that underlie slow fault slip phenomena, including recent ...

Nature Communications, 2017 In the Nankai subduction zone a low-velocity zone (LVZ) has been detected. Here, the authors present shear wave velocity profiles to show that low frequency earthquakes correlate with the distribution of the LVZ in the Nankai subduction zone.

The role of elasticity in slab bending [PDF]
, 2014 International audiencePrevious studies showed that plate rheology exerts a dominant control on the shape and velocity of subducting plates. Here, we perform a systematic investigation of the role of elasticity in slab bending, using fully dynamic 2-D ...

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.

Progress in Earth and Planetary Science, 2018 Ocean drilling in the Nankai Trough forearc suggests a new scenario for the evolution of the Nankai subduction zone. Continuous subduction since the Late Cretaceous has been a common tectonic scenario, although the plate subduction was transferred from ...

Historical seismograms for unravelling a mysterious earthquake: The 1907 Sumatra Earthquake [PDF]
, 2010 History of instrumental seismology is short. Seismograms are available only for a little more than 100 years; high-quality seismograms are available only for the last 50 years and the seismological database is very limited in time. To extend the database,

Distribution of dehalogenation activity in subseafloor sediments of the Nankai Trough subduction zone [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2013 Halogenated organic matter buried in marine subsurface sediment may serve as a source of electron acceptors for anaerobic respiration of subseafloor microbes. Detection of a diverse array of reductive dehalogenase-homologous ( rdhA ) genes suggests that subseafloor organohalide-respiring microbial communities may ...

Bridging the gap between low-frequency and very-low-frequency earthquakes
Earth, Planets and Space, 2020 Slow earthquakes that are observed in the > 1 Hz frequency band are called tectonic tremor or low-frequency earthquakes (LFEs) and those in the 0.01–0.10 Hz band are called very-low-frequency earthquakes (VLFEs).

A Comparative Study of the Sumatran Subduction-Zone Earthquakes of 1935 and 1984 [PDF]
, 2002 A M_s 7.7 earthquake struck the western, equatorial coast of Sumatra in December 1935. It was the largest event in the region since the two devastating giant earthquakes of 1833 and 1861.

Geotechnical behavior of mudstones from the Shimanto and Boso accretionary complexes, and implications for the Nankai accretionary prism [PDF]
, 2014 Triaxial shear tests on mudstone samples from the Shimanto Belt and the Boso accretionary complexes (SW Japan and central Japan) were carried out. Pre-exhumation burial depths in the two paleo-accretionary prisms were up to 9,000 m and about 1,000 m for
