Evidence for fluid-assisted shear failure in a ductile shear zone: tectonic tremor in the geologic record? [PDF]

, 2015
Includes bibliographical references.2015 Summer.Recent direct observations of tectonic tremor below the seismogenic zone of large fault zones have emphasized the significance of coeval ductile and brittle processes at high temperatures.

Tectonic Tremor Explained by Successive Ruptures of Clustered Quartz‐Filled Shear Veins

Geophysical Research Letters
A 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

Aeromagnetic mapping of fault architecture along Lagos–Ore axis, southwestern Nigeria

Open Geosciences, 2020
A seismic wave is released when there is sudden displacement on a fault plane. The passage of this wave along the fault plane or within the lithosphere could result in ground shaking or vibration at the surface of the Earth.

New Insights Into Hikurangi Subduction Inputs and Megathrust Host Rocks Spanning Along‐Margin Changes in Fault Slip Behavior

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract The seismic behavior of subduction megathrusts varies spatially and is influenced by the properties of subducting plates, including their sedimentary cover. Characterizing these subduction inputs is essential for understanding the mechanisms behind fault slip variability.

Enhanced deep learning approach for detecting and locating tectonic tremors in the Nankai subduction zone

Earth, Planets and Space
Tectonic tremors are key indicators of slow-slip phenomena, and detecting them accurately is a challenging task. Conventional techniques often fail to detect tremors during periods of intense tremor activity.

Observation of Shallow Slow Earthquakes by Distributed Acoustic Sensing Using Offshore Fiber‐Optic Cable in the Nankai Trough, Southwest Japan

Geophysical Research Letters, 2023
Off Cape Muroto area, along the Nankai Trough in southwest Japan, is a typical area with adjacent occurrences of slow and megathrust earthquakes. High‐resolution monitoring of slow earthquakes is necessary to understand tectonic conditions.

OBS Data Mining Reveals Seismic Structure and Dynamics of the Oceanic Blanco Transform Fault, Northeast Pacific

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Deformation along oceanic transform faults is partitioned between seismic and aseismic slip, controlled by lithology, thermal structure, and fluid circulation. We analyze one year of data from a 54‐station ocean bottom seismometer network deployed across the Blanco Transform Fault (BTF), Northeast Pacific.

Does deep tectonic tremor occur in the central-eastern Mediterranean basin?

, 2020
Tectonic tremor has been observed at the roots of many fault systems around the Pacific rim, including convergent and transform plate boundaries.

Defining the Relationship between Seismicity and Deformation at Regional and Local Scales [PDF]

, 2013
In this thesis, I use source inversion methods to improve understanding of crustal deformation along the Nyainquentanglha (NQTL) Detachment in Southern Tibet and the Piceance Basin in northwestern Colorado.
