Data assimilation for fault slip monitoring and short-term prediction of spatio-temporal evolution of slow slip events: application to the 2010 long-term slow slip event in the Bungo Channel, Japan

Earth, Planets and Space
Monitoring and predicting fault slip behaviors in subduction zones is essential for understanding earthquake cycles and assessing future earthquake potential. We developed a data assimilation method for fault slip monitoring and the short-term prediction

Subdaily Slow Fault Slip Dynamics Captured by Low‐Frequency Earthquakes [PDF]

AGU Advances, 2023
Geodetic positioning is the geophysical record of reference for slow slip events, but typical daily solutions limit studies of the evolution of slow slip to its long‐term dynamics.

Seismic Swarms Unveil the Mechanisms Driving Shallow Slow Slip Dynamics in the Copiapó Ridge, Northern Chile

Geophysical Research Letters
Like earthquakes, slow slip events release elastic energy stored on faults. Yet, the mechanisms behind slow slip instability and its relationship with seismicity are debated. Here, we use a seismo‐geodetic deployment to document a shallow slow slip event

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

, 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.

Spatial and temporal evolution of a long term slow slip event : the 2006 Guerrero Slow Slip Event [PDF]

, 2011
P>The Guerrero 2006 Slow Slip Event (SSE), Mexico, one of the world's largest observed SSEs, was recorded at 15 continuous GPS stations. This event provides the opportunity to analyse in detail the spatial and temporal evolution of slip at depth, and to ...

Spatiotemporal slip distribution associated with the 2012–2016 Tokai long-term slow slip event inverted from GNSS data

Geoscience Letters, 2023
We used Global Navigation Satellite System (GNSS) time series data to estimate the spatiotemporal slip distribution for a long-term slow slip event (L-SSE) that occurred in the Tokai region, central Japan, from 2012 to 2016.

Observing and Modeling the Spectrum of a Slow Slip Event [PDF]

, 2018
We estimate and model the normalized moment rate power spectrum of large slow slip events in Cascadia. We estimate the spectrum using data from GPS‐derived slip inversions, borehole strain records, and beamforming‐based tremor amplitudes.

Very Low Frequency Earthquakes in Between the Seismogenic and Tremor Zones in Cascadia?

AGU Advances, 2022
Megathrust earthquakes and their associated tsunamis cause some of the worst natural disasters. In addition to earthquakes, a wide range of slip behaviors are present at subduction zones, including slow earthquakes that span multiple orders of spatial ...

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

Frontiers 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 ...

Objective detection of long-term slow slip events along the Nankai Trough using GNSS data (1996–2016)

Earth, Planets and Space, 2017
This paper presents a method for objective detection of long-term slow slip events with durations on the order of years, on the plate boundary along the Nankai Trough, relying on global navigation satellite system daily coordinate data.
