Probing the nature of low-frequency earthquakes through the deconvolution of tectonic tremor
Journal of Geophysical Research: Solid Earth, 2023 Currently there are two end-member views of low-frequency earthquakes (LFEs). One is that they result from stick-slip behavior of Mxed brittle patches that are mechanically distinct from the surrounding, creeping, fault. The other is that they represent the high-frequency limit of stochastic accelerations and decelerations of slip on the fault, with ...

Frontiers in Astronomy and Space Sciences, 2023 To explore the correlation between earthquakes and spatial ultra-low frequency electric field disturbances and to study the phenomenon of seismic ionospheric disturbances, this study uses 3 years of electric field ULF band data from 2019 to 2021 observed

Fortnightly modulation of San Andreas tremor and low-frequency earthquakes [PDF]
Proceedings of the National Academy of Sciences, 2016 Significance The sun and moon exert a gravitational tug on Earth that stretches and compresses crustal rocks. This cyclic stressing can promote or inhibit fault slip, particularly at the deep roots of faults. The amplitude of the solid Earth tide varies over a fortnightly (2-wk) cycle, as the sun and moon change their relative positions in ...

Observations of stress relaxation before earthquakes [PDF]
, 2004 Theory and observations suggest that seismic shear wave splitting, caused by fluid-saturated stress-aligned microcracks, directly monitors low-level deformation before fracturing, faulting and earthquakes occur.

Metamaterial foundation for seismic wave attenuation for low and wide frequency band
Scientific Reports, 2023 Metamaterials are periodic structures made by repeating a unit cell. Such a structure shows frequency-specific wave attenuation behaviour. In this work, a 2D metamaterial foundation is proposed for the seismic protection of buildings.

Deep crustal electromagnetic structure of Bhuj earthquake region (India) and its implications [PDF]
, 2010 The existence of fluids and partial melt in the lower crust of the seismically active Kutch rift basin (on the western continental margin of India) owing to underplating has been proposed in previous geological and geophysical studies. This hypothesis is

Deep learning detects uncataloged low-frequency earthquakes across regions
SeismicaDocumenting the interplay between slow deformation and seismic ruptures is essential to understand the physics of earthquakes nucleation. However, slow deformation is often difficult to detect and characterize.
