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

Observing and Modeling the Spectrum of a Slow Slip Event [PDF]
Journal of Geophysical Research: Solid Earth, 2018 AbstractWe 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. The normalized power spectrum initially decreases with frequency but then may flatten at periods of 1 to 10

Imaging evolution of Cascadia slow-slip event using high-rate GPS [PDF]
Scientific Reports, 2022 The slip history of short-term slow slip event (SSE) is typically inferred from daily Global Positioning System (GPS) data, which, however, cannot image the sub-daily processes, leaving the underlying mechanisms of SSEs elusive.

Slip bursts during coalescence of slow slip events in Cascadia [PDF]
Nature Communications, 2020 <p>Both laboratory experiments and dynamic simulations suggest that earthquakes can be preceded by a precursory phase of slow slip. Observing processes leading to an acceleration or spreading of slow slip along faults is therefore key to understand the dynamics potentially leading to seismic ruptures.

Spatiotemporal slip distributions associated with the 2018–2019 Bungo Channel long-term slow slip event inverted from GNSS data [PDF]
Scientific Reports, 2022 Long-term slow slip events (L-SSEs) have repeatedly occurred beneath the Bungo Channel in southwestern Japan with durations of several months to a couple of years, with a recurrence interval of approximately 6 years.

Revealing the cluster of slow transients behind a large slow slip event. [PDF]
Sci Adv, 2018 A slow slip event is a cluster of small aseismic slip transients intermittently interrupted by relocking of the plate interface.

Filling the Gap in Cascadia: The Emergence of Low‐Amplitude Long‐Term Slow Slip
Geochemistry, Geophysics, Geosystems, 2021 Long‐term slow slip events have been observed at several subduction zones around the globe, where they play an integral part in strain release along megathrust faults.

The Ocean's Impact on Slow Slip Events
Geophysical Research Letters, 2020 We test the hypothesis that ocean seafloor pressures impart stresses that alter the initiation or termination of transient slow slip events (SSEs) on shallow submarine and near‐coastal faults, using simulated seafloor pressures and a new catalog of SSEs ...

Recurrent slow slip event likely hastened by the 2011 Tohoku earthquake. [PDF]
Proc Natl Acad Sci U S A, 2012 Slow slip events (SSEs) are another mode of fault deformation than the fast faulting of regular earthquakes. Such transient episodes have been observed at plate boundaries in a number of subduction zones around the globe. The SSEs near the Boso Peninsula, central Japan, are among the most documented SSEs, with the longest repeating history, of almost ...

Maximum size and magnitude of injection-induced slow slip events. [PDF]
Sci AdvFluid injections can induce aseismic slip, resulting in stress changes that may propagate faster than pore pressure diffusion, potentially triggering seismicity at substantial distances from injection wells. Constraining the maximum extent of these aseismic ruptures is, thus, important for better delineating the influence zone of injections concerning ...
