Bridging the gap between low-frequency and very-low-frequency earthquakes [PDF]
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).

Low-frequency earthquakes along the Ryukyu Islands triggered by teleseismic earthquakes [PDF]
Earth, Planets and Space, 2021 Tremors and low-frequency earthquakes (LFEs), which occur in the plate interface, can provide useful information about the state of aseismic stress transfer in mega-earthquake fault zones.

Distribution of low-frequency earthquakes accompanying the very low frequency earthquakes along the Ryukyu Trench [PDF]
Earth, Planets and Space, 2017 This study investigated the activity and distribution of low-frequency earthquakes (LFEs) accompanying the very low frequency earthquakes (VLFEs) in the central and southern Ryukyu Trench.

Comparison of statistical low-frequency earthquake activity models
Earth, Planets and Space, 2023 Slow earthquakes are slow fault slip events. Quantifying and monitoring slow earthquake activity characteristics are important, because they may change before large earthquakes occur.

The slow self-arresting nature of low-frequency earthquakes [PDF]
Nature Communications, 2021 Low-frequency earthquakes are a series of small earthquakes with lower dominant frequencies than ordinary earthquakes. By comparing the simulated earthquakes with the real data, we find that low-frequency earthquakes represent an earthquake rupture ...

Sporadic low-velocity volumes spatially correlate with shallow very low frequency earthquake clusters [PDF]
Nature Communications, 2017 In the Nankai subduction zone a low-velocity zone (LVZ) has been detected. Here, the authors present shear wave velocity profiles to show that low frequency earthquakes correlate with the distribution of the LVZ in the Nankai subduction zone.

Self-similarity of low-frequency earthquakes [PDF]
Scientific Reports, 2020 AbstractLow-frequency earthquakes are a particular class of slow earthquakes that provide a unique source of information on the physical processes along a subduction zone during the preparation of large earthquakes. Despite increasing detection of these events in recent years, their source mechanisms are still poorly characterised, and the relation ...

Décollement geometry controls on shallow very low frequency earthquakes [PDF]
Scientific Reports, 2022 AbstractRecent studies have documented the occurrence of shallow very low frequency earthquakes (VLFE) in subduction zones. The heterogeneity of the materials or stresses that act on the plate interface results in the variable slip rate. Stress on the décollement can be controlled by the décollement geometry and the regional stress, which is also able ...

Nuclear Engineering and Technology, 2022 A nuclear power plant (NPP) piping is designed against low-frequency earthquakes. However, earthquakes that can occur at NPP sites in the eastern part of the United States, northern Europe, and Korea are high-frequency earthquakes.

What makes low-frequency earthquakes low frequency?
Science Advances, 2023 Low-frequency earthquakes are repetitive seismic events that occur downdip of the seismogenic megathrust where slow aseismic fault slip dominates the tectonic budget. These tiny events, distinct from regular earthquakes, have the potential to provide in-situ constraints on the fault rheology where slow slip occurs, but are hard to study due to their ...
