Earthquake Swarms, Slow Slip and Fault Interactions at the Western‐End of the Hellenic Subduction System Precede the Mw 6.9 Zakynthos Earthquake, Greece

open access: yesGeochemistry, Geophysics, Geosystems, 2020
The month‐to‐year‐long deformation of the Earth's crust where active subduction zones terminate is poorly explored. Here we report on a multidisciplinary data set that captures the synergy of slow‐slip events, earthquake swarms and fault interactions ...

Evidence of Localized Failure Along Altered Basaltic Blocks in Tectonic Mélange at the Updip Limit of the Seismogenic Zone: Implications for the Shallow Slow Earthquake Source

open access: yesGeochemistry, Geophysics, Geosystems, 2020
Field studies have led to several interpretations on the mechanics behind slow earthquake phenomena downdip of the seismogenic zone. To date, field studies have not examined the shallow subduction interface which may also host slow earthquake phenomena ...

Strongly Scattering Medium Along Slow Earthquake Fault Zones Based on New Observations of Short‐Duration Tremors

open access: yesGeophysical Research Letters, 2023
Tremors are a type of slow earthquake with long‐duration signals compared to ordinary earthquakes. The long signals have been considered to solely reflect their long source process.

Link between the Nankai underthrust turbidites and shallow slow earthquakes

open access: yesScientific Reports, 2023
Trench sediments such as pelagic clay or terrigenous turbidites have long been invoked to explain the seismogenic behavior of the megathrust fault (i.e., décollement).

Precise Monitoring of Pore Pressure at Boreholes Around Nankai Trough Toward Early Detecting Crustal Deformation

open access: yesFrontiers in Earth Science, 2021
In our recent study, we detected the pore pressure change due to the slow slip event (SSE) in March 2020 at the two borehole stations (C0002 and C0010), where the other borehole (C0006) close to the Nankai Trough seems not because of instrumental drift ...

Earthquakes of the Nepal Himalaya : Towards a Physical Model of the Seismic Cycle [PDF]

open access: yes, 2013
Home to hundreds of millions of souls and land of excessiveness, the Himalaya is also the locus of a unique seismicity whose scope and peculiarities still remain to this day somewhat mysterious.

Defining the Relationship between Seismicity and Deformation at Regional and Local Scales [PDF]

open access: yes, 2013
In this thesis, I use source inversion methods to improve understanding of crustal deformation along the Nyainquentanglha (NQTL) Detachment in Southern Tibet and the Piceance Basin in northwestern Colorado.

Recovery of the recurrence interval of Boso slow slip events in Japan

open access: yesEarth, Planets and Space, 2019
We present the spatiotemporal evolution of the Boso slow slip event with a moment of 20 × 1018 N m that occurred in June 2018; such events, which have a duration of 1–2 weeks, have repeatedly occurred off the Boso peninsula, east Japan.

Editorial: Pre-earthquake observations and methods for earthquake forecasting and seismic hazard reduction

open access: yes, 2023
Understanding the governing principles, which include long-term tectonic loading, sluggish nucleation, and rapid fracture propagation, enables estimation of the stress level and change during geophysical observations in seismically active locations ...

Foreshock properties illuminate nucleation processes of slow and fast laboratory earthquakes

open access: yesNature Communications, 2023
Understanding the connection between seismic activity and the earthquake nucleation process is a fundamental goal in earthquake seismology with important implications for earthquake early warning systems and forecasting.
