Uneven aftershock distribution of Wenchuan Ms8.0 earthquake and possible mechanism

Geodesy and Geodynamics, 2011
The aftershock activity of Wenchuan Ms8.0 earthquake showed different spatial and temporal distributions along two different segments of the Longmenshan fault. This difference was likely the result of segmentation of the earthquake rupture process, which

Slip distributions on active normal faults measured from LiDAR and field mapping of geomorphic offsets: an example from L'Aquila, Italy, and implications for modelling seismic moment release [PDF]

, 2014
Surface slip distributions for an active normal fault in central Italy have been measured using terrestrial laser scanning (TLS), in order to assess the impact of changes in fault orientation and kinematics when modelling subsurface slip distributions ...

Damage localization as a possible precursor of earthquake rupture

, 2000
Based on the concepts of statistical mesoscopic damage mechanics, the rupture of a heterogeneous medium is investigated in terms of numerical simulations of a network model, subjected to simple shear loading.

Source rupture process inversion of the 2013 Lushan earthquake, China

, 2013
:The spatial and temporal slip distribution of the Lushan earthquake was estimated using teleseismic body wave data. To perform a stable inversion, we applied smoothing constraints and determined their optimal relative weights on the observed data using ...

The complex rupture evolution of the long and slow, tsunamigenic 2021 South Sandwich Islands earthquake

Scientific Reports
On August 21, 2021, a large earthquake occurred in the South Sandwich subduction zone, and the associated tsunami was widely observed. To robustly analyse the detailed seismic source process of this long-source duration (over 200 s) event occurring in a ...

Discrete radiation sources of the 2024 Noto Peninsula earthquake: linking teleseismic pulses and near-field observations

Earth, Planets and Space
Understanding the rupture process of large earthquakes is critical; however, standard rupture process inversions require stabilizing constraints, which can obscure which features are genuinely required by the data.

Kinematic source rupture on listric faults for the 2024 Noto Peninsula, Japan, earthquake (Mw 7.5) estimated from near-field strong-motion waveforms

Earth, Planets and Space
On January 1, 2024, an Mw 7.5 reverse-fault earthquake occurred along the submarine active faults just offshore of the Noto Peninsula in central Japan. This earthquake is one of the largest inland crustal earthquakes that ever recorded in Japan.
