Cataloging Tectonic Tremor Energy Radiation in the Cascadia Subduction Zone
Journal of Geophysical Research: Solid Earth, 2021AbstractFor the past ∼12 years the Pacific Northwest Seismic Network has been automatically detecting and locating tectonic tremor across the Cascadia subduction zone, resulting in a catalog of more than 500,000 tremor epicenters to date, which has served as a valuable resource for tremor and slip research.

Improvements to Cross-Station Analysis of Tectonic Tremor
Cross-station analysis of tectonic tremor, as introduced by John Armbruster for long (150 s) windows and extended by Allan Rubin to short (4 s) windows, has afforded the highest precision mapping of tremor locations achieved to date. Cross-station locations have been used to a) reveal tremor epicentral distributions over broad (to ~104 km2) areas that ...Michael Bostock +2 more

Recent Advances in Tectonic Tremor Research
Since its discovery about 25 years ago, tectonic tremor has been identified in many subduction zones and transform plate boundaries worldwide, greatly advancing our understanding of regional tectonics and earthquake generation processes. Tremor detection and catalog construction continue to progress in many regions.openaire +1 more source
Tectonic Analysis of Mine Tremor Mechanisms from the Upper Silesian Coal Basin
pure and applied geophysics, 1996Fault network of the Upper Silesian Coal Basin (USCB) is built of sets of strike-slip, oblique-slip and dip-slip faults. It is a typical product of force couple which acts evenly with the parallel of latitude, causing horizontal and anti-clockwise smovement of rock-mass. Earlier research of focal mechanisms of mine tremors, using a standard fault plane

Tidal sensitivity of shallow tectonic tremors in northeastern Japan
Shallow tectonic tremors along the northeastern Japan subduction zone show regional differences in their spatiotemporal evolution, raising the question of whether their response to tidal stressing also varies along strike. We analyze the tremor catalogue obtained by Sagae et al. (JGR, 2025, e2025JB031348) for the period from August 2016 to August 2024.Yishuo Zhou +7 more

Surface-Wave Potential for Triggering Tectonic (Nonvolcanic) Tremor--Corrected
Bulletin of the Seismological Society of America, 2012Abstract Source processes commonly posed to explain instances of remote dynamic triggering of tectonic (nonvolcanic) tremor by surface waves include frictional failure and various modes of fluid activation. The relative potential for Love‐ and Rayleigh‐wave dynamic stresses to trigger tectonic tremor through failure on critically stressed thrust and ...

Experimental tectonic tremors triggered at subduction zone conditions
The origin of tectonic tremors, low-amplitude and long-duration seismic signals, observed at depth greater than 20-30km at some of the world’s tectonic plate boundaries, remains enigmatic. Here, olivine + antigorite mineral assemblages, containing up to 75 vol.% of the hydrous bearing phase, thought as analogues for dry and water-rich subducting ...Schubnel, Alexandre +7 more
