Journal of Geophysical Research - Solid Earth, 2022 Swarms are bursts of earthquakes without an obvious mainshock. Some have been observed to be associated with transient aseismic fault slip, while others are thought to be related to fluids.

Link between the Nankai underthrust turbidites and shallow slow earthquakes
Scientific 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).

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 ...

Recovery of the recurrence interval of Boso slow slip events in Japan
Earth, 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.

Frictional Mechanics of Slow Earthquakes [PDF]
Journal of Geophysical Research: Solid Earth, 2018 AbstractTectonic faults slip in a wide range of modes that span from slow slip events to dynamic rupture. A growing body of observations document this spectrum of failure modes in many geologic settings. However, the physical mechanisms that dictate slow slip are not understood.

Bridging the gap between low-frequency and very-low-frequency earthquakes
Earth, Planets and Space, 2020 Slow earthquakes that are observed in the > 1 Hz frequency band are called tectonic tremor or low-frequency earthquakes (LFEs) and those in the 0.01–0.10 Hz band are called very-low-frequency earthquakes (VLFEs).

Foreshock properties illuminate nucleation processes of slow and fast laboratory earthquakes
Nature 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.

A 220,000-year-long continuous large earthquake record on a slow-slipping plate boundary
Science Advances, 2020 A 220-ka-long Mw ≥ 7.0 earthquake record reveals an unexpectedly high seismicity rate on a slow-slipping plate boundary. Large earthquakes (magnitude ≥ 7.0) are rare, especially along slow-slipping plate boundaries.

Nature Communications, 2022 Laboratory earthquake experiments reproduce delayed earthquake triggering, similar to aftershocks, as a result of propagating slow slip fronts. The speed of the fronts can be highly sensitive to fault stress levels left behind by previous earthquakes.

Static Source Properties of Slow and Fast Earthquakes [PDF]
Journal of Geophysical Research: Solid Earth, 2020 AbstractThe source characteristics of slow and fast earthquakes provide a window into the mechanical properties of faults. In particular, the average stress drop controls the evolution of friction, fault slip, and event magnitude. However, this important source property is typically inferred from the analysis of seismic waves and is subject to many ...
