Complex in situ stress states in a deep shale gas reservoir in the southern Sichuan Basin, China: From field stress measurements to in situ stress modeling

Rui Yong et al.

Summary: This study established a 3D in situ stress model of the Longmaxi shale gas formation in the southern Sichuan Basin through field in situ stress measurements, revealing a complex stress state. The presence of faults was found to alter both the magnitudes and orientations of in situ stress, leading to higher risk of slipping in certain faults.

Central shutdown and surrounding activation of aftershocks from megathrust earthquake stress transfer

Shinji Toda et al.

Summary: This study analyzes data from aftershocks of megathrust earthquakes and identifies the spatiotemporal pattern of aftershocks, which is crucial for mitigating seismic hazard. The study finds that the aftershock patterns can be explained by rate and state Coulomb stress transfer. It also suggests that seismicity in the rupture zone may persist for centuries, while seismicity in the surrounding area decays over several decades.

BSPASS: A Beam Search-Based Phase Association and Source Scanning Earthquake Location Method

Chaoliang Wang et al.

Summary: A novel method for seismic phase association and source scanning is proposed, which accurately determines the location of earthquakes with high precision and demonstrates practicality and accuracy in seismic networks with different station spacings. The method performs well even for earthquakes at the network boundary, and shows flexibility and robustness when dealing with Gaussian noise levels.

Stress heterogeneity in the Changning shale-gas field, southern Sichuan Basin: Implications for a hydraulic fracturing strategy

Rui Liu et al.

Summary: The stress analysis conducted in the Changning shale-gas field showed that stress distribution is closely related to factors such as thrust faults and lithology, and the risk of induced seismicity can be effectively reduced by controlling the injection method of fracturing fluid.

Tectonic evolution of the Sichuan Basin, Southwest China

Shugen Liu et al.

Summary: Surface deformation in the Sichuan basin is influenced by two weak extension and compression episodes, leading to the formation of specific structures. The evolution of the basin appears to be controlled by deformation from its peripheral orogens rather than deep lithospheric and mantle processes.

A Decade of Lessons Learned from the 2011 Tohoku-Oki Earthquake

N. Uchida et al.

Summary: Research has shown that there were indications of a potential great megathrust earthquake in NE Japan before the 2011 Tohoku earthquake, but a consensus assessment of the hazard was lacking. Since the earthquake, studies have made significant progress in revealing aspects such as coseismic rupture, aftershocks, and slow earthquakes.

Seismogenic Faults of the Changning Earthquake Sequence Constrained by High-Resolution Seismic Profiles in the Southwestern Sichuan Basin, China

Renqi Lu et al.

Summary: Seismic activity in the Changning area of southwestern Sichuan basin, China, has significantly increased since 2014, possibly due to salt mining or shale gas exploration. The study reveals the characteristics of seismogenic faults and the well-developed pre-existing fault system which makes the region vulnerable to induced earthquakes. The reactivation of basement fault system highlights the unstable state of the local tectonic stress field, potentially increasing seismic risk in the area due to industrial activities in the southwestern Sichuan basin.
