The Transient and Intermittent Nature of Slow Slip

AGU Advances, 2020
To first order, faults are locked while stress builds up to a devastating earthquake. However, we know that faults also slip slowly. After decades of geophysical observation, slow slip is now recognized as part of a continuum of transient deformation ...

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.

Slow Slip Events in New Zealand: Irregular, yet Predictable? [PDF]

Geophysical Research Letters
Current earthquake forecasting approaches are mainly based on probabilistic assumptions, as earthquakes seem to occur randomly. Such apparent randomness can however be caused by deterministic chaos, rendering deterministic short‐term forecasts possible ...

Shallow very-low-frequency earthquakes accompany slow slip events in the Nankai subduction zone [PDF]

Nature Communications, 2018
Slow earthquakes are now increasingly recognised to occur at plate boundaries globally. Here, the authors examine seafloor observational data from the Nankai trough and find that very-low-frequency events and slow-slip events frequently occur together ...

Secondary acceleration of slip fronts driven by slow slip event coalescence in subduction zones [PDF]

Nature Communications
Abstract The coalescence of slow slip events (SSEs) in subduction zones has been proposed as a potential precursor to large earthquakes, yet the physical conditions under which SSE fronts coalesce remain poorly understood. Here, we investigate coalescing SSEs along the Cascadia subduction zone. Using Global Navigation Satellite System

Origin of slow earthquake statistics in low-friction soft granular shear [PDF]

Nature Communications
Slow earthquakes differ from regular earthquakes in their slower moment release and size distribution dominated by smaller events. However, the physical origin of these slow earthquake statistics remains controversial.

Near Real-Time Cascadia Slow Slip Events

Geophysical Journal International
Slow Slip Events (SSEs) play an important role in the seismic cycle, participating in the moment budget of active faults. SSEs can be monitored via space geodesy (e.g., Global Navigation Satellite System, GNSS). One of the major challenges when studying geodetic data is that they record the deformation due to many active sources (e.g., tectonic ...

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

Slow slip events and flank instability at Mt. Etna volcano (Italy) [PDF]

, 2022
Highlights • A set of slow slip events occurred at Mt. Etna volcano is analyzed. • Two distinct families of slow slip events have been detected. • Most of the deformation affecting the eastern flank occurs aseismically.

Effects of episodic slow slip on seismicity and stress near a subduction-zone megathrust

Nature Communications, 2021
Large slow slip earthquakes and tremor occur in subduction zones near the locked megathrust. Combined analysis of changes in slab seismicity and stress field near the times of such slow slip events highlights the role of fluid in promoting slow slip.
