The 2010–2011 South Rigan (Baluchestan) earthquake sequence and its implications for distributed deformation and earthquake hazard in southeast Iran [PDF]

, 2013
We investigate the source processes and tectonic significance of two earthquakes that occurred on 2010 December 20 (Mw 6.5) and 2011 January 27 (Mw 6.2) within a desert region south of the town of Rigan, SE Iran. The two earthquakes, which we refer to as

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 ...

Paleoearthquakes of the Düzce fault (North Anatolian Fault Zone): Insights for large surface faulting earthquake recurrence [PDF]

, 2008
Copyright 2008 by the American Geophysical Union.The 12 November 1999 Mw 7.1 earthquake ruptured the Düzce segment of the North Anatolian Fault Zone and produced a ∼40-km-long surface rupture.

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

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.

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 ...

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.

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.

Applying the Coulomb Failure Function with an optimally oriented plane to the 2008 Mw 7.9 Wenchuan earthquake triggering [PDF]

, 2010
The Coulomb failure function (CFF) quantitatively describes static stress changes in secondary faults near the source fault of an earthquake. CFF can be employed to monitor how static stress transfers and then shed some light on the probability of ...
