Despite decades of observational, laboratory and theoretical studies, the processes leading
to large earthquake generation remain enigmatic. However, recent observations provide …

Earthquakes and the faults upon which they occur interact over a wide range of spatial and
temporal scales. In addition, many aspects of regional seismicity appear to be stochastic …

A nearly 20-year hiatus in major seismic activity in southern California ended on 4 July 2019
with a sequence of intersecting earthquakes near the city of Ridgecrest, California. This …

Faults are rarely completely smooth, with topographic undulations coming from the
distribution of asperities along the fault surface. Understanding the effects of fault surface …

The vibrant evolutionary patterns made by earthquake swarms are incompatible with
standard, effectively two-dimensional (2D) models for general fault architecture. We …

This paper presents the preliminary results of an extensive study of the mapping the
distribution of landslides triggered by the Wenchuan earthquake in Sichuan Province …

Field observations of mature crustal faults suggest that slip in individual events occurs
primarily within a thin shear zone,< 1–5 mm, within a finely granulated, ultracataclastic fault …

Damage surrounding the core of faults is represented by deformation on a range of scales
from microfracturing of the rock matrix to macroscopic fracture networks. The spatial …

Earthquake slip distributions are asymmetric along strike, but the reasons for the asymmetry
are unknown. We address this question by establishing empirical relations between …

The thicknesses of fault rock and fault zones and the fault normal separations for breached
and intact relay zones each show a positive correlation with fault displacement. The …
