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 …

Dynamic slab segmentation due to brittle–ductile damage in the outer rise

TV Gerya, D Bercovici, TW Becker - Nature, 2021 - nature.com
Subduction is the major plate driving force, and the strength of the subducting plate controls
many aspects of the thermochemical evolution of Earth. Each subducting plate experiences …

The nature of the Pacific plate as subduction inputs to the northeastern Japan arc and its implication for subduction zone processes

G Fujie, S Kodaira, K Obana, Y Yamamoto… - Progress in Earth and …, 2023 - Springer
Devastating megathrust earthquakes and slow earthquakes both occur along subducting
plate interfaces. These interplate seismic activities are strongly dependent on the nature of …

Slab transport of fluids to deep focus earthquake depths—thermal modeling constraints and evidence from diamonds

SB Shirey, LS Wagner, MJ Walter, DG Pearson… - AGU …, 2021 - Wiley Online Library
The nature and cause of deep earthquakes remain enduring unknowns in the field of
seismology. We present new models of thermal structures of subducted slabs traced to …

Northern Chile intermediate-depth earthquakes controlled by plate hydration

L Cabrera, S Ruiz, P Poli… - Geophysical Journal …, 2021 - academic.oup.com
We investigate the variations of the seismic source properties and aftershock activity using
kinematic inversions and template-matching for six large magnitude intermediate-depth …

Re‐Examining Temporal Variations in Intermediate‐Depth Seismicity

S Wimpenny, T Craig, S Marcou - Journal of Geophysical …, 2023 - Wiley Online Library
Abstract Changes in the frequency of intermediate‐depth (60–300 km) earthquakes in
response to static stress transfer can provide insights into the mechanisms of earthquake …

High‐Pressure Mechanical Properties of Talc: Implications for Fault Strength and Slip Processes

Y Boneh, M Pec, G Hirth - Journal of Geophysical Research …, 2023 - Wiley Online Library
The hydrous mineral talc is stable over a relatively large P‐T field and can form due to fluid
migration and metamorphic reactions in mafic and ultramafic rocks and in faults along plate …

Oceanic intraplate faulting as a pathway for deep hydration of the lithosphere: Perspectives from the Caribbean

BT Bishop, S Cho, L Warren, L Soto-Cordero… - …, 2023 - pubs.geoscienceworld.org
The recycling of water into the Earth's mantle via hydrated oceanic lithosphere is believed to
have an important role in subduction zone seismicity at intermediate depths. Hydration of …

Filling the gap in a double seismic zone: Intraslab seismicity in Northern Chile

C Sippl, B Schurr, T John, S Hainzl - Lithos, 2019 - Elsevier
Double seismic zones (DSZs) of intermediate-depth intraslab seismicity are observed in
many subduction zones around the globe, and have been related to dehydration reactions …

Impact of bending-related faulting and oceanic-plate topography on slab hydration and intermediate-depth seismicity

J Geersen, C Sippl, N Harmon - Geosphere, 2022 - pubs.geoscienceworld.org
It is commonly assumed that intermediate-depth seismicity is in some way linked to
dehydration reactions inside subducting oceanic plates. Although there is growing evidence …
