Rupture Process of the 26 May 2019 Mw 8.0 Northern Peru Intermediate‐Depth Earthquake and Insights Into Its Mechanism

Geophysical Research Letters, 2020
In the Nazca‐South American subduction zone, the subducted slab is flattened beneath northern Andes, called the Peruvian flat slab. The 2019 Mw 8.0 northern Peru intermediate‐depth normal‐faulting earthquake occurred at the leading edge of the Peruvian ...

Rupture process of the 2014 Orkney earthquake, South Africa

Tạp chí Khoa học và Công nghệ biển, 2017
An earthquake has occurred at 10:22:33 UT on 5 August 2014 in the Klerksdorp district, the North West province of South Africa. Its hypocenter is located beneath an Orkney town, where more than 10 gold mines exist. The Council for Geoscience (CGS) in South Africa reported that the magnitude and depth was ML5.5 and 4.7 km, respectively.

Rupture process of the March 3, 1985 Chilean earthquake [PDF]

Geophysical Research Letters, 1986
The March 3, 1985 central Chile earthquake (Ms=7.8) ruptured a well studied seismic gap along the Chilean subduction zone. The epicenter of this event is located near the center of an approximately 300 km long region which ruptured in a great event in 1906 (Mw=8.2).

A rock brittleness index based on the postpeak energy release rate and damage surface characteristics for brittle hard rock

Deep Underground Science and Engineering, EarlyView.
This study examines energy evolution in rock rupture via triaxial direct shear tests, exploring the impact of confining pressure and temperature on fracture surface randomness. A novel energy‐based brittleness index is proposed, validated experimentally, and compared with existing methods for reliability and accuracy.

A teleseismic finite-fault rupture model for the August 17, 1999, İzmit earthquake (Mw = 7.6): implications for the seismic nucleation phase

Annals of Geophysics, 2012
A linear finite-fault inversion procedure is applied to teleseismically recorded broadband P and SH velocity waveforms of the August 17, 1999, İzmit earthquake, to derive spatial and temporal distributions of the co-seismic slip over the representative ...

A Multiplex Rupture Sequence Under Complex Fault Network Due To Preceding Earthquake Swarms During the 2024 Mw 7.5 Noto Peninsula, Japan, Earthquake

Geophysical Research Letters
A devastating earthquake with moment magnitude 7.5 occurred in the Noto Peninsula in central Japan on 1 January 2024. We estimate the rupture evolution of this earthquake from teleseismic P‐wave data using the potency‐density tensor inversion method ...

Two‐stage composite megathrust rupture of the 2015 Mw8.4 Illapel, Chile, earthquake identified by spectral‐element inversion of teleseismic waves

Geophysical Research Letters, 2016
The Mw8.4 Illapel earthquake occurred on 16 September was the largest global event in 2015. This earthquake was not unexpected because the hypocenter was located in a seismic gap of the Peru‐Chile subduction zone. However, the source model derived from 3‐
