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 …

Venus interior structure and dynamics

SE Smrekar, A Davaille, C Sotin - Space Science Reviews, 2018 - Springer
No two rocky bodies offer a better laboratory for exploring the conditions controlling interior
dynamics than Venus and Earth. Their similarities in size, density, distance from the sun, and …

The Hindu Kush slab break-off as revealed by deep structure and crustal deformation

SK Kufner, N Kakar, M Bezada, W Bloch… - Nature …, 2021 - nature.com
Break-off of part of the down-going plate during continental collision occurs due to tensile
stresses built-up between the deep and shallow slab, for which buoyancy is increased …

Months-long thousand-kilometre-scale wobbling before great subduction earthquakes

JR Bedford, M Moreno, Z Deng, O Oncken, B Schurr… - Nature, 2020 - nature.com
Megathrust earthquakes are responsible for some of the most devastating natural disasters.
To better understand the physical mechanisms of earthquake generation, subduction zones …

Subduction earthquake cycles controlled by episodic fluid pressure cycling

L Dal Zilio, T Gerya - Lithos, 2022 - Elsevier
In subduction zones, fluids are often invoked to explain slip processes on the megathrust,
from great earthquakes to slow-slip events and tectonic tremors. However, it is unclear how …

Laboratory earthquakes triggered during eclogitization of lawsonite-bearing blueschist

S Incel, N Hilairet, L Labrousse, T John… - Earth and Planetary …, 2017 - Elsevier
The origin of intermediate-depth seismicity has been debated for decades. A substantial
fraction of these events occurs within the upper plane of Wadati–Benioff double seismic …

The importance of grain size to mantle dynamics and seismological observations

J Dannberg, Z Eilon, U Faul… - Geochemistry …, 2017 - Wiley Online Library
Grain size plays a key role in controlling the mechanical properties of the Earth's mantle,
affecting both long‐time‐scale flow patterns and anelasticity on the time scales of seismic …

Zooming into the Hindu Kush slab break-off: A rare glimpse on the terminal stage of subduction

SK Kufner, B Schurr, C Haberland, Y Zhang… - Earth and Planetary …, 2017 - Elsevier
The terminal stage of subduction sets in when the continental margin arrives at the trench
and the opposite forces of the sinking slab and buoyant continent extend and ultimately …

Fossil intermediate-depth earthquakes in subducting slabs linked to differential stress release

M Scambelluri, G Pennacchioni, M Gilio… - Nature …, 2017 - nature.com
The cause of intermediate-depth (50–300 km) seismicity in subduction zones is uncertain. It
is typically attributed either to rock embrittlement associated with fluid pressurization, or to …

Earthquake rupture below the brittle-ductile transition in continental lithospheric mantle

GA Prieto, B Froment, C Yu, P Poli, R Abercrombie - Science Advances, 2017 - science.org
Earthquakes deep in the continental lithosphere are rare and hard to interpret in our current
understanding of temperature control on brittle failure. The recent lithospheric mantle …
