Tectonic tremor characterized by principal-component analysis in the vicinity of central Chile and Argentina

Journal of South American Earth Sciences, 2019
No conclusive evidence has been presented to date for tectonic tremor (TT) in the vicinity of central Chile, where the Nazca Plate is subducting beneath the South American Plate. Subduction in our experimental location (roughly 35.5° S, 70.5° W) is steep

Tackling the challenges of tectonic tremor localization using differential traveltimes and Bayesian inversion

Geophysical Journal International, 2023
Episodic tremor and slip events in Northern Cascadia produce low-frequency, emergent seismic signals, often referred to as tectonic tremor. Methods designed to locate tremor face two challenges that increase the likelihood of producing low quality ...

Spatiotemporal evolution of tremor activity near the Nankai Trough trench axis inferred from the spatial distribution of seismic amplitudes

Earth, Planets and Space, 2022
Slow earthquakes have gained importance due to their proximity to the focal regions of megathrust earthquakes. Among slow earthquakes, tectonic tremors have the highest dominant frequency and are thus best resolved.

Tidal Response in Shallow Tectonic Tremors [PDF]

Geophysical Research Letters, 2017
AbstractVarious types of slow earthquakes (e.g., tectonic tremors and slow slip events) have been reported in tectonic zones, especially in the subduction zone. The tidal response of a tremor is considered to be strongly related to the weak friction state of the plate interface, and many studies have reported observational evidence of such correlation ...

Tectonic tremors in the Northern Mexican subduction zone remotely triggered by the 2017 M w8.2 Tehuantepec earthquake

Earth, Planets and Space, 2021
Surface waves from the 2017 M w8.2 Tehuantepec earthquake remotely triggered tectonic tremors in the Jalisco region, approximately 1000 km WNW in the northern Mexican subduction zone.

Shallow tectonic tremor activities in Hyuga-nada, Nankai subduction zone, based on long-term broadband ocean bottom seismic observations

Earth, Planets and Space, 2021
The study of slow earthquake activity, which occurs in the shallow and deep sides of seismogenic zone, is crucial for understanding subduction zones, including variations in frictional properties with depth and interplate coupling.

Changes of Event Size Distribution During Episodes of Shallow Tectonic Tremor, Nankai Trough

Geophysical Research Letters, 2021
Slow earthquakes follow a power‐law size distribution with an exponential taper for the largest events. We investigated changes in the size distribution of shallow tectonic tremor events during two prolonged tremor episodes (>1 month) along the Nankai ...

Tidal Modulation and Tectonic Implications of Tremors in Taiwan [PDF]

Journal of Geophysical Research: Solid Earth, 2018
AbstractWe present results from 6 years of tremor observations in a continental subduction zone where the continental crust of Eurasia is colliding with the Philippine Sea Plate, forming a collisional orogen. During 2007–2012, 1,893 tremor events with durations ranging from 60 to 2,216 s were identified and located.

Crust and upper-mantle seismic anisotropy variations from the coast to inland in central and Southern Mexico (2): Correlations with Tectonic Tremor

Geophysical Journal International, 2021
Seismic anisotropy in the flat slab region of Mexico is compared with tectonic tremor activity. The anisotropy is observed in three separate horizontal layers using a novel technique with receiver functions.

Phase dependent modulation of tremor amplitude in essential tremor through thalamic stimulation [PDF]

, 2013
High frequency deep brain stimulation of the thalamus can help ameliorate severe essential tremor. Here we explore how the efficacy, efficiency and selectivity of thalamic deep brain stimulation might be improved in this condition.
