Continental crust anisotropy measurements from tectonic tremor in Cascadia

Journal of Geophysical Research: Solid Earth, 2017
AbstractWe present new observations of crustal anisotropy in the southern Cascadia fore arc from tectonic tremor. The abundance of tremor activity in Oregon and northern California during slow‐slip events offers an enormous amount of information with which to measure and analyze anisotropy in the upper brittle continental crust.

Investigation of Single‐Station Classification for Short Tectonic Tremor in Taiwan

Journal of Geophysical Research: Solid Earth, 2019
AbstractTectonic tremor in Taiwan is known for its short duration and weak amplitude. Recent observations from the mountain area (Central Range) allows us to document such type of tectonic tremor recorded at a close distance and to investigate a single station technique for a minute‐long tremor.

Experimental constraints on the controlling mechanisms of tectonic tremors

2023
Tectonic (or non-volcanic) tremors have been extensively documented at subduction zones and are considered as the signature of transport processes of dehydration-related fluids in subduction zones, often recorded in close association with geodetically observed shear induced slow-slip events. However, to the best of our knowledge, they have not yet been

Tectonic Tremor Recorded by Ocean Bottom Seismometers

Seismological Research Letters, 2013
Widespread observations of tremor and slow slip in different tectonic environments (Rubinstein et al. , 2009; Schwartz and Rokosky, 2007) reveal that these newly recognized processes play fundamental roles in accommodating and marking fault motion. Understanding the relationship between fault dynamics, stable (slow) slip, and more rapid earthquake ...

Detecting Deep Tectonic Tremor in Taiwan with a Dense Array

Bulletin of the Seismological Society of America, 2015
Abstract 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.

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 ...

Search for Tectonic Tremor on the Central North Anatolian Fault, Turkey

Bulletin of the Seismological Society of America, 2015
Abstract 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

A Glimpse Into the Future of Tectonic Tremor Monitoring

Journal of Geophysical Research: Solid Earth
Abstract 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 ...

Cataloging Tectonic Tremor Energy Radiation in the Cascadia Subduction Zone

Journal of Geophysical Research: Solid Earth, 2021
AbstractFor 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.
