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 …

Hierarchical interlocked orthogonal faulting in the 2019 Ridgecrest earthquake sequence

ZE Ross, B Idini, Z Jia, OL Stephenson, M Zhong… - Science, 2019 - science.org
A nearly 20-year hiatus in major seismic activity in southern California ended on 4 July 2019
with a sequence of intersecting earthquakes near the city of Ridgecrest, California. This …

Detailed rupture imaging of the 25 April 2015 Nepal earthquake using teleseismic P waves

W Fan, PM Shearer - Geophysical Research Letters, 2015 - Wiley Online Library
We analyze the rupture process of the 25 April 2015 Nepal earthquake with globally
recorded teleseismic P waves. The rupture propagated east‐southeast from the hypocenter …

Slab morphology and deformation beneath Izu-Bonin

H Zhang, F Wang, R Myhill, H Guo - Nature communications, 2019 - nature.com
Seismic tomography provides unique constraints on the morphology, the deformation, and
(indirectly) the rheology of subducting slabs. We use teleseismic double-difference P-wave …

Polarized plate tectonics

C Doglioni, G Panza - Advances in geophysics, 2015 - Elsevier
The mechanisms driving plate motion and the Earth's geodynamics are still not entirely
clarified. Lithospheric volumes recycled at subduction zones or emerging at rift zones testify …

Inferring Earth's discontinuous chemical layering from the 660-kilometer boundary topography

W Wu, S Ni, JCE Irving - Science, 2019 - science.org
Inferring blocked mantle convection The boundaries between rocks with different physical
properties in Earth's interior come from either a change in crystal structure or a change in …

Gutenberg–Richter law for deep earthquakes revisited: A dual-mechanism hypothesis

Z Zhan - Earth and Planetary Science Letters, 2017 - Elsevier
Deep earthquake b values appear to vary with slab thermal state and earthquake
magnitude. The physical reason for the variations and the relation with deep rupture …

The 2021 South Sandwich Island Mw 8.2 Earthquake: A Slow Event Sandwiched Between Regular Ruptures

Z Jia, Z Zhan, H Kanamori - Geophysical Research Letters, 2022 - Wiley Online Library
We determined the rupture sequence of the 12 August 2021 Mw 8.2 South Sandwich Island
earthquake which appears to be a complex sequence in both time and space. Notable …

Global rupture parameters for deep and intermediate‐depth earthquakes

P Poli, GA Prieto - Journal of Geophysical Research: Solid …, 2016 - Wiley Online Library
We investigate the global rupture parameters for deep and intermediate‐depth earthquakes.
From measurements of rupture duration and radiated seismic energy we estimate stress …

Supershear rupture in a Mw 6.7 aftershock of the 2013 Sea of Okhotsk earthquake

Z Zhan, DV Helmberger, H Kanamori, PM Shearer - Science, 2014 - science.org
Earthquake rupture speeds exceeding the shear-wave velocity have been reported for
several shallow strike-slip events. Whether supershear rupture also can occur in deep …
