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.

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

Geophysical Journal International, 2010
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 constrain the characteristics of a large SSE. We perform an inversion in two steps.

Return of the Atacama deep Slow Slip Event: The 5-year recurrence confirmed by continuous GPS

Physics of the Earth and Planetary Interiors, 2022
months, the 2020 event had the same characteristics as the 2014 SSE. It occurred in the same area and at the same depth, repeating a similar pattern of surface deformation.

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.

Continuous Tremor Activity With Stable Polarization Direction Following the 2014 Large Slow Slip Event in the Hikurangi Subduction Margin Offshore New Zealand

Journal of Geophysical Research - Solid Earth, 2021
Many types of slow earthquakes have been discovered at subduction zones around the world. However, the physical process of these slow earthquakes is not well understood.

Dilatant strengthening as a mechanism for slow slip events [PDF]

Journal of Geophysical Research: Solid Earth, 2010
The mechanics of slow slip events (SSE) in subduction zones remain unresolved. We suggest that SSE nucleate in areas of unstable friction under drained conditions, but as slip accelerates dilatancy reduces pore pressure p quenching instability. Competition between dilatant strengthening and thermal pressurization may control whether slip is slow or ...

Long-lived shallow slow-slip events on the Sunda megathrust [PDF]

Nature Geoscience, 2021
During most of the time between large earthquakes at tectonic plate boundaries, surface displacement time series are generally observed to be linear. This linear trend is interpreted as a result of steady stress accumulation at frictionally locked asperities on the fault interface.

Slip-rate-dependent friction as a universal mechanism for slow slip events [PDF]

Nature Geoscience, 2020
A growing body of observations worldwide has documented fault slip transients that radiate little or no seismic energy. The mechanisms that govern these slow slip events (SSEs) and their wide range of depths, slip rates, durations, stress drops and recurrence intervals remain poorly known.

Systematic Detection of Short‐Term Slow Slip Events in Southcentral Alaska

Geophysical Research Letters, 2023
Slow slip events (SSEs) are important for the slip budget along a megathrust fault. Although the recurrence of weeks‐long short‐term SSEs (S‐SSEs) in southcentral Alaska has been suggested, a large amount of noise prevented us from detecting discrete ...

Slow Slip Event at Kilauea Volcano [PDF]

Eos, Transactions American Geophysical Union, 2010
Early in the morning of 1 February 2010 (UTC; early afternoon 31 January 2010 local time), continuous Global Positioning System (GPS) and tilt instruments detected a slow slip event (SSE) on the south flank of Kilauea volcano, Hawaii. The SSE lasted at least 36 hours and resulted in a maximum of about 3 centimeters of seaward displacement.
