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 …

An introductory review of the thermal structure of subduction zones: III—Comparison between models and observations

PE van Keken, CR Wilson - Progress in Earth and Planetary Science, 2023 - Springer
The thermal structure of subduction zones is fundamental to our understanding of the
physical and chemical processes that occur at active convergent plate margins. These …

Continental collisions and the origin of subcrustal continental earthquakes

D McKenzie, J Jackson… - Canadian Journal of …, 2019 - pubs.geoscienceworld.org
The existence of subcrustal continental earthquakes beneath the Alpine–Himalayan Belt

Seismic imaging of the Java subduction zone: New insight into arc volcanism and seismogenesis

F Xie, Z Wang, D Zhao, R Gao, X Chen - Tectonophysics, 2023 - Elsevier
The Java subduction zone is located in the southern part of Southeast Asia, where the
strong plate convergence results in clustered arc volcanoes and intense seismicity. To better …

Empirical evaluation of the control period TC for intermediate-depth earthquakes: application for Romania

F Pavel, S Yaghmaei-Sabegh - Natural Hazards, 2023 - Springer

depth earthquakes. A ground motion database of about 700 recordings from 25 intermediate …

The rupture mechanisms of intraslab earthquakes: A multiscale review and re-evaluation

E Hosseinzadehsabeti, EC Ferré, P Persaud… - Earth-Science …, 2021 - Elsevier
The initiation of intraslab earthquakes and their location depend on multiple factors such as
slab heterogeneity, pre-subduction anisotropy, thermal parameters and the metamorphic …

Aftershock productivity of intermediate-depth earthquakes in Japan

SX Chu, GC Beroza - Geophysical Journal International, 2022 - academic.oup.com
Intermediate-depth earthquakes occur at temperatures and pressures thought to prohibit
brittle fracture and are deficient in aftershocks compared to shallow earthquakes. We search …

First‐principles investigations of antigorite polysomatism under pressure

J Tsuchiya, T Mizoguchi, S Inoué… - Journal of Geophysical …, 2024 - Wiley Online Library
Antigorite is the high‐temperature member of the serpentine group minerals and is broadly

Earthquake Depth Phase Extraction With P Wave Autocorrelation Provides Insight Into Mechanisms of Intermediate‐Depth Earthquakes

H Fang, RD van der Hilst - Geophysical Research Letters, 2019 - Wiley Online Library
Constraining the mechanism of earthquakes in subduction zones requires adequate
estimates of source location and near‐source elastic properties. In this study, we propose a …
