Detecting Deep Tectonic Tremor in Taiwan with a Dense Array
Bulletin of the Seismological Society of America, 2015Abstract We perform a systematic detection of deep tectonic tremor beneath the southern Central Range in Taiwan using a dense, small‐aperture seismic array. Deployed in February 2011, the array has been recording tectonic tremor nearly continuously for 134 days, including tremor triggered by the 2011 M w 9.0 Tohoku‐Oki earthquake.

Search for Tectonic Tremor on the Central North Anatolian Fault, Turkey
Bulletin of the Seismological Society of America, 2015Abstract Tectonic tremor has previously been observed along two major transform faults: the San Andreas fault (SAF) and the Alpine fault (AF); and we extend the search for tectonic tremor to another transform fault, the North Anatolian fault (NAF). We investigate a two‐year‐long temporary broadband seismic deployment on an ∼400 km long NAF segment in

Surface-Wave Potential for Triggering Tectonic (Nonvolcanic) Tremor
Bulletin of the Seismological Society of America, 2010Source 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 vertical ...

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.

A Glimpse Into the Future of Tectonic Tremor Monitoring
Journal of Geophysical Research: Solid EarthAbstract Tectonic tremor is a weak, long‐duration seismic signal often observed in subduction zones and on some other plate‐bounding faults. Because of tremor's characteristically low amplitude (and low signal‐to‐noise) and lack of clear phase arrivals, detecting and locating tremor usually requires techniques ...

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

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

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
