Mechanisms and implications of deep earthquakes

Z Zhan - Annual Review of Earth and Planetary Sciences, 2020 - annualreviews.org
Deep earthquakes behave like shallow earthquakes but must have fundamentally different
physical processes. Their rupture behaviors, magnitude-frequency statistics, and aftershocks …

Teleseismic constraints on the geological environment of deep episodic slow earthquakes in subduction zone forearcs: A review

P Audet, YH Kim - Tectonophysics, 2016 - Elsevier
More than a decade after the discovery of deep episodic slow slip and tremor, or slow
earthquakes, at subduction zones, much research has been carried out to investigate the …

Transdimensional inversion of receiver functions and surface wave dispersion

T Bodin, M Sambridge, H Tkalčić… - … research: solid earth, 2012 - Wiley Online Library
We present a novel method for joint inversion of receiver functions and surface wave
dispersion data, using a transdimensional Bayesian formulation. This class of algorithm …

Seismic evidence for overpressured subducted oceanic crust and megathrust fault sealing

P Audet, MG Bostock, NI Christensen, SM Peacock - Nature, 2009 - nature.com
Water and hydrous minerals play a key part in geodynamic processes at subduction zones,,
by weakening the plate boundary, aiding slip and permitting subduction—and indeed plate …

Juan de Fuca slab geometry and its relation to Wadati‐Benioff zone seismicity

PA McCrory, JL Blair, F Waldhauser… - Journal of …, 2012 - Wiley Online Library
A new model of the subducted Juan de Fuca plate beneath western North America allows
first‐order correlations between the occurrence of Wadati‐Benioff zone earthquakes and …

Joint inversion of surface wave dispersion and receiver functions: a Bayesian Monte-Carlo approach

W Shen, MH Ritzwoller… - Geophysical Journal …, 2013 - academic.oup.com
A non-linear Bayesian Monte-Carlo method is presented to estimate a Vsv model beneath
stations by jointly interpreting Rayleigh wave dispersion and receiver functions and …

High pore pressures and porosity at 35 km depth in the Cascadia subduction zone

SM Peacock, NI Christensen, MG Bostock… - …, 2011 - pubs.geoscienceworld.org
In the Cascadia subduction zone, beneath southern Vancouver Island at 25–45 km depth,
converted teleseismic waves reveal an∼ 5-km-thick landward-dipping layer with …

Thermal–petrological controls on the location of earthquakes within subducting plates

GA Abers, J Nakajima, PE van Keken, S Kita… - Earth and Planetary …, 2013 - Elsevier
We find that in young and warm subducting plates, earthquakes occur just below the Moho.
In older plates, earthquakes occur throughout the subducting oceanic crust, as well as the …

Cascadia low frequency earthquakes at the base of an overpressured subduction shear zone

AJ Calvert, MG Bostock, G Savard… - Nature …, 2020 - nature.com
In subduction zones, landward dipping regions of low shear wave velocity and elevated
Poisson's ratio, which can extend to at least 120 km depth, are interpreted to be all or part of …

Magnitudes and moment‐duration scaling of low‐frequency earthquakes beneath southern Vancouver Island

MG Bostock, AM Thomas, G Savard… - Journal of …, 2015 - Wiley Online Library
We employ 130 low‐frequency earthquake (LFE) templates representing tremor sources on
the plate boundary below southern Vancouver Island to examine LFE magnitudes. Each …
