The big impact of small quakes on tectonic tremor synchronization. [PDF]
Sci AdvTectonic tremor tracks the repeated slow rupture of certain major plate boundary faults. One of the most perplexing aspects about tremor is that some fault segments produce strongly periodic, spatially extensive tremor episodes, while others have more disorganized, asynchronous activity. Here, we measure the size of segments that activate synchronously

Single station seismic observations enable high resolution localization of tectonic tremor sources using a vision transformer [PDF]
Scientific ReportsPrecisely locating tectonic tremor events is essential for understanding subduction zone dynamics. However, the lack of impulsive phase arrivals typically necessitates multi-station observations, posing a fundamental challenge for high-resolution ...

Seismological Structures on Bimodal Distribution of Deep Tectonic Tremor [PDF]
Geophysical Research Letters, 2021 AbstractDeep tectonic tremors occur at the downdip extent of the seismogenic zone due to fluid processes. Beneath the northeastern Kii Peninsula, southwestern Japan, there is an along‐dip bimodal distribution of tremor. However, no constraint exists on the structures controlling that distribution. We extract detailed seismological structures from multi‐

Forecasting tectonic tremor activity using a renewal process model
Progress in Earth and Planetary Science, 2022 In many tectonically active regions of the world, a variety of slow deformation phenomena have been discovered and collectively termed slow earthquakes.

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.

Does Deep Tectonic Tremor Occur in the Central-Eastern Mediterranean Basin? [PDF]
Journal of Geophysical Research: Solid Earth, 2021 Abstract Tectonic tremor has been observed at the roots of many fault systems around the Pacific rim, including convergent and transform plate boundaries. The extent to which deep tremor signals are prevalent along fault systems elsewhere, including the Mediterranean basin, has not yet been documented in detail.

Tectonic tremor: The chatter of mafic underplating
SeismicaTremor is a weak seismic signal accompanying slow fault slip at plate boundaries. The relationship between tremor and slow slip and the tremor source mechanism have been widely debated, owing largely to the challenge of accurately locating tremor in ...

Tectonic Tremor Reveals Slow Deformation Along the Antarctic–South American Subduction Zone
Geophysical Research LettersThe Antarctic–South American subduction zone is among the least explored convergent margins and lacks documented large interplate earthquakes despite ongoing convergence.

Depth and Thickness of Tectonic Tremor in the Northeastern Olympic Peninsula [PDF]
Journal of Geophysical Research: Solid Earth, 2022 AbstractTectonic tremor has been explained as a swarm of low‐frequency earthquakes (LFEs), which are located on a narrow fault at the plate boundary. However, due to the lack of clear impulsive phases in the tremor signal, it is difficult to determine the depth of the tremor source with great precision.
