Variations in Cascadia Low‐Frequency Earthquake Behavior With Downdip Distance
Geochemistry Geophysics Geosystems, 2019 We identify and characterize four different low‐frequency earthquake (LFE) families (LFEs 1–4, ordered updip to downdip) that span the width of the transition zone in the Cascadia Subduction Zone beneath western Washington State.

The model of self-generated seismo-electromagnetic oscillations of the LAI system [PDF]
Solid Earth, 2011 Very low frequency (VLF) electromagnetic radiation (in diapason 1 kHz–1 MHz) in the atmosphere, generated during an earthquake preparation period, may be connected with the linear size characterising the expected earthquake focus.

Activation of very low frequency earthquakes by slow slip events in the Ryukyu Trench [PDF]
Geophysical Research Letters, 2015 AbstractLong‐term activity of shallow very low frequency earthquakes (VLFEs) in the Ryukyu Trench, unassociated with recent large thrust earthquakes, was analyzed using a broadband seismometer network. The distribution of shallow VLFEs was divided into three large clusters.

Shallow very-low-frequency earthquakes accompany slow slip events in the Nankai subduction zone [PDF]
Nature Communications, 2018 AbstractRecent studies of slow earthquakes along plate boundaries have shown that tectonic tremor, low-frequency earthquakes, very-low-frequency events (VLFEs), and slow-slip events (SSEs) often accompany each other and appear to share common source faults.

Improved Resolution across the Global Seismographic Network: A New Era in Low-Frequency Seismology
The Seismic Record, 2022 The Global Seismographic Network (GSN)—a global network of ≈150 very broadband stations—is used by researchers to study the free oscillations of the Earth (≈0.3–10 mHz) following large earthquakes. Normal-mode observations can provide information about

Slow Earthquakes in the Microseism Frequency Band (0.1–1.0 Hz) off Kii Peninsula, Japan
Geophysical Research Letters, 2018 It is difficult to detect the signal of slow deformation in the 0.1–1.0 Hz frequency band between tectonic tremors and very low frequency events, where microseism noise is dominant.

Analysis of the local lithospheric magnetic activity before and after Panzhihua Mw = 6.0 earthquake (30 August 2008, China) [PDF]
Natural Hazards and Earth System Sciences, 2011 Lithospheric ultra low frequency (ULF) magnetic activity is recently considered as a very promising candidate for application to short-time earthquake forecasting. However the intensity of the ULF lithospheric magnetic field is very weak and often masked

Frontiers in Earth Science, 2023 Three destructive earthquakes occurred in Pingwu and Songpan, Sichuan Province, China, between August 16 and 23, 1976. Due to the seismic monitoring capability at that time, the ground motion characteristics of these earthquakes are very vague.
