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

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-dip** 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 …
