TLDR
In this paper, aftershock activity of Wenchuan M s8.0 earthquake showed different spatial and temporal distributions along two different segments of the Longmenshan fault, which may be the result of the fault segmentation in its long-term geotectonic condition.About:

Assessment of Space-Time Hazard of Large Aftershocks of the 2008 Mw7.9 Wenchuan Earthquake
TL;DR: In this paper, the authors constructed a new hazard model to describe the occurrence rate of aftershocks in a study region along the Longmenshan fault, which is a combination of the Reasenberg-Jones (RJ) model and a spatial hazard model that is obtained by taking a reference of previous earthquakes in the study region.

Estimating spatiotemporal aggregation scales by revisiting the spatiotemporal L‐function
TL;DR: In this article , a modified spatio-temporal L-function is proposed to estimate the spatiotemporal aggregation scales accurately, which can reveal process evolutions, such as spatio temporal scopes of seismic sequence and spatio temporally spread extents of an epidemic.

The role of stress transfer in earthquake occurrence
TL;DR: In this paper, it was shown that small, sudden stress changes cause large changes in seismicity rate, where rates climb where the stress increases (aftershocks) and fall when the stress drops.

Introduction to Special Section: Stress Triggers, Stress Shadows, and Implications for Seismic Hazard
TL;DR: This paper reviewed many published works and presented a compilation of quantitative earthquake interaction studies from a stress change perspective, which provided some clues about certain aspects of earthquake mechanics, but much work remains before we can understand the complete story of how earthquakes work.
