Spatiotemporal Variation of Tectonic Tremor Activity Before the Tohoku‐Oki Earthquake [PDF]
Journal of Geophysical Research: Solid Earth, 2018 A slow slip event (SSE) and tectonic tremors occurred approximately 1.5 month prior to the occurrence of the 2011 Tohoku‐Oki earthquake near the Japan Trench.

Earth and Planetary Science Letters, 2021 Episodes of tectonic tremor are observed in the Nankai accretionary prism close to the trough axis; however, their non-impulsive signals and the distortion of seismic signals in the accretionary prism make it challenging to accurately estimate their ...

Chemical origin of tectonic tremor [PDF]
Nature Geoscience, 2019 Tectonic tremor may ultimately be caused by in situ fluid overpressure generated by chemical reactions between a subducting slab and the mantle, according to field and microstructural observations of a shear zone.

Possible Shallow Tectonic Tremor Signals Near the Deformation Front in Central Cascadia
SeismicaTo better constrain the locking state of the shallow Cascadia megathrust, we investigate whether shallow tectonic tremor occurs near the deformation front at ~44.5°N during 2015-2024. We focus on two cabled buried ocean bottom seismometers (OBSs) on the

Tectonic Tremor Explained by Successive Ruptures of Clustered Quartz‐Filled Shear Veins
Geophysical Research LettersA tectonic tremor is a successive seismic signal observed along plate boundaries in subduction zones. However, the source processes and mechanisms responsible for the tremor remain unclear. Quartz‐filled shear and extension veins are clustered in tens to

Variety and spatial heterogeneity of tectonic tremor worldwide [PDF]
Journal of Geophysical Research: Solid Earth, 2012 Deep tectonic tremor occurs at various sites worldwide, and the source characteristics are heterogeneous, even at small scales. In this study, tremor sources were determined using data sets of seismic waveforms from various locations, some of which are not well recognized as being a site of tremor activity.

Low-frequency tremor-like episodes before the 2023 M W 7.8 Türkiye earthquake linked to cement quarrying [PDF]
Scientific ReportsRecent advances in artificial intelligence have enhanced the detection and identification of transient low-amplitude signals across the entire frequency spectrum, shedding light on deformation processes preceding natural hazards.

Tectonic tremor and deep slow slip on the Alpine Fault [PDF]
Geophysical Research Letters, 2012 Tectonic tremor is characterized by persistent, low-frequency seismic energy seen at major plate boundaries. Although predominantly associated with subduction zones, tremor also occurs along the deep extension of the strike-slip San Andreas Fault.

Using Tectonic Tremor to Constrain Seismic Wave Attenuation in Cascadia [PDF]
Geophysical Research Letters, 2017 Tectonic tremor can be used to constrain seismic wave attenuation for use in ground motion prediction equations in regions where moderately sized earthquakes occur infrequently.
