Rapid disaster assessment of a M 6.8 earthquake in Dingri, Xizang, China

Earthquake Research Advances
We conducted a rapid seismic intensity assessment of a M 6.8 earthquake in Dingri, Xizang, using a ground motion parameter attenuation model based on the shortest fault distance combined with either an empirical equation for the surface rupture length or

Measuring and Modeling Viscoelastic Relaxation of the Lithosphere with Application to the Northern Volcanic Zone, Iceland [PDF]

, 2010
Viscoelastic relaxation of the stress perturbation caused by an earthquake or diking event can produce measurable ground deformation over 100 km away from the source. We consider the role of viscoelastic relaxation in two different contexts.

Geometric Complexity of Earthquake Rupture Surfaces Preserved in Pseudotachylyte Networks [PDF]

Journal of Geophysical Research: Solid Earth, 2018
AbstractRecent earthquakes have demonstrated that rupture may propagate through geometrically complex networks of faults. Ancient exhumed faults have the potential to reveal the details of complex rupture at seismogenic depths. We present a new set of field observational criteria for determining which of a population of pseudotachylyte fault veins ...

Epistemic uncertainty in fault geometry effects earthquake rupture behavior

, 2022
It is well established in the seismology community that geometric complexity plays an important role for a fault’s seismotectonic behavior. It affects the initiation, propagation and termination of an earthquake as well as influencing the stress-slip ...

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

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

A numerical approach for estimating the probability of earthquake surface rupture

This study is part of the Probabilistic Fault Displacement Hazard Analysis (PFDHA) framework, which assesses the hazard posed by coseismic surface faulting to infrastructure systems (e.g., lifelines, nuclear power plants, and dams) located on or near an earthquake fault trace.

Verification of high rupture speed of the 1990 Luzon earthquake, Philippines from Taiwan seismic network observations

Geoscience Letters
On July 16, 1990, a Mw 7.7 earthquake struck central Luzon, Philippines. The event produced more than 100 km of surface rupture along the Philippine Fault system. Seismologists conducted detailed investigations of the overall source rupture process using

THE M(W)7.8 2016 KAIKOURA EARTHQUAKE: SURFACE FAULT RUPTURE AND SEISMIC HAZARD CONTEXT

, 2017
We provide a summary of the surface fault ruptures produced by the Mw7.8 14 November 2016 Kaikōura earthquake, including examples of damage to engineered structures, transportation networks and farming infrastructure produced by direct fault surface ...

Sustained supershear rupture during the 2025 Mandalay, Myanmar earthquake

Communications Earth & Environment
The 2025 Mw 7.8 Myanmar earthquake ruptured the Sagaing fault, where sparse near-fault seismic observations limit source characterization. Here, we integrate optical imagery, InSAR, finite-fault slip inversion, back-projection (BP), and dynamic rupture ...
