Diverse rupture processes in the 2015 Peru deep earthquake doublet [PDF]

Science Advances, 2016
The nearby M w 7.5 and M w 7.6 events in a deep earthquake doublet under Peru have diverse stress drops and radiation efficiency.

The dynamic rupture process of the 2001 Geiyo, Japan, earthquake [PDF]

Geophysical Research Letters, 2004
The 2001, Geiyo earthquake (Mw = 6.7) occurred as a normal fault event within the young subducting Philippine Sea plate. We investigate a dynamic rupture process of the earthquake and estimate the dynamic parameters. Firstly, the space‐time distribution of slip of the earthquake, i.e., the kinematic model, was investigated by inverting the near‐field ...

Application of seismogram synthesis to the study of earthquake source from strong motion records

Annals of Geophysics, 1994
We present the results of an analysis of the Michoacan and Landers earthquakes to constrain the kinematic description of the rupture process. The example of the Michoacan earthquake shows that a crack type model is better a dislocation model to describe ...

Estimation of the Nucleation Location and Rupture Extent of the 1850 Xichang, Sichuan, China, Earthquake by Dynamic Rupture Simulations on a Multi‐Segment Stepover Structure

Earth and Space Science, 2023
We simulated the rupture dynamics and ground motion of the 1850 Xichang, China, earthquake on the Zemuhe fault, which consists of the Lijinbao segment, the Dajing segment, the Chechejie segment, and the Songxin segment, with the curved grid finite ...

Rupture-dependent breakdown energy in fault models with thermo-hydro-mechanical processes [PDF]

Solid Earth, 2020
Substantial insight into earthquake source processes has resulted from considering frictional ruptures analogous to cohesive-zone shear cracks from fracture mechanics.

A multiple asymmetric bilateral rupture sequence derived from the peculiar tele-seismic P-waves of the 2025 Mandalay, Myanmar earthquake

Seismica
A large strike-slip earthquake occurred in central Myanmar on March 28, 2025. The aftershock distribution suggests that the rupture of the mainshock propagated mainly to the south. However, a large-amplitude phase lasting 20 s, followed by a short-period

Breaking the Cycle: Short Recurrence and Overshoot of an M9-class Kamchatka Earthquake

Seismica
M9-class megathrust earthquakes in subduction zones are generally thought to release slip deficits on the plate interface accumulated over centuries. However, the 2025 Kamchatka earthquake (Mw 8.8-8.9) ruptured nearly the same area as the 1952 Mw 9.0 ...

Critical Ground Motion for Resilient Building Design Considering Uncertainty of Fault Rupture Slip

Frontiers in Built Environment, 2018
The process of theoretical ground motion generation consists of (i) the fault rupture process, (ii) the wave propagation from the fault to the earthquake bedrock, (iii) the site amplification.

Updip Fluid Flow in the Crust of the Northeastern Noto Peninsula, Japan, Triggered the 2023 Mw 6.2 Suzu Earthquake During Swarm Activity

Geophysical Research Letters, 2023
An Mw 6.2 earthquake occurred in Suzu, northeastern Noto Peninsula, Japan, on 5 May 2023, followed by many aftershocks. Before this mainshock‐aftershock sequence, an intense earthquake swarm lasted in the vicinity for 2.5 years.

Tomographic imaging of the earthquake rupture process

Geophysical Research Letters, 1984
To advance our understanding of the earthquake rupture process, we must develop methods that will map observations into the space‐time variation of seismic moment release on the fault plane. While the temporal history of overall moment release is relatively easy to obtain from P‐waves, there has been no objective quantitative method available to ...
