Observing Earthquake-Induced Velocity Change on the Rock Slope Following the 2021 M 7.4 Maduo Earthquake 780 km Away

Sustainability, 2022
Velocity changes (dv/v) during and after earthquakes are important indicators for understanding the earthquake-induced mechanical damage evolution of rock slopes. However, studying slope responses associated with various seismic loading still remains challenging due to limited in situ observations.

Research on the extraction of pre-seismic anomalies in borehole strain data of the Maduo earthquake based on the SVMD-Informer model [PDF]

Natural Hazards and Earth System Sciences
Earthquake is a major natural disaster triggered by the accumulation and release of crustal stress, and the accurate extraction of pre-seismic anomaly signals is crucial to improve the earthquake prediction capability. In this study, an anomaly detection

Coulomb stress changes associated with the M7.3 Maduo earthquake and implications for seismic hazards

Natural Hazards Research, 2021
On May 21, 2021, the M7.3 Maduo earthquake occurred within the Bayan Har Block, one of the most seismically active regions in the Tibetan Plateau. This aroused attention to the seismic hazards in this block. Understanding the stress transfer to adjacent faults is important for assessing seismic hazards.

Broadband ground motion simulation using a hybrid approach of the May 21, 2021 M7.4 earthquake in Maduo, Qinghai, ChinaKey points

Earthquake Science, 2023
In this study, the broadband ground motions of the 2021 M7.4 Maduo earthquake were simulated to overcome the scarcity of ground motion recordings and the low resolution of macroseismic intensity map in sparsely populated high-altitude regions.

Recognition of Earthquake Surface Ruptures Using Deep Learning

Applied Sciences, 2022
Investigating post-earthquake surface ruptures is important for understanding the tectonics of seismogenic faults. The use of unmanned aerial vehicle (UAV) images to identify post-earthquake surface ruptures has the advantages of low cost, fast data ...

The complex dynamics of the 2023 Kahramanmaraş, Turkey, Mw 7.8-7.7 earthquake doublet [PDF]

, 2023
The destructive 2023 moment magnitude (Mw) 7.8-7.7 earthquake doublet ruptured multiple segments of the East Anatolian Fault system in Turkey. We integrated multiscale seismic and space-geodetic observations with multifault kinematic inversions and ...

Liquefaction Behavior of Bushehr Coastal Carbonate Sand [PDF]

, 2022
Over the past few years, liquefaction phenomena have always been one of the challenging issues in geotechnical engineering. The occurrence of liquefaction is due to cyclic tensions resulting from zero effective stress in the soil mass.

The role of antithetic faults in transferring displacement across contractional relay zones on normal faults [PDF]

, 2023
Contractional relay zones between pairs of normal faults are sometimes associated with multiple antithetic faults in a geometry similar to that found in Riedel shear zones.

Stress triggering of the 2022 Lushan–Maerkang earthquake sequence by historical events and its implication for fault stress evolution in eastern Tibet

Frontiers in Earth Science, 2023
It remains unknown how stress triggering causes earthquakes in the eastern Tibetan Plateau following the Wenchuan Earthquake in 2008. The MS 6.1 Lushan earthquake on 1 June 2022 in a seismic gap between the 2008 MW 7.9 Wenchuan earthquake and the 2013 MW
