Aftershock sequence relocation of the 2021 MS7.4 Maduo Earthquake, Qinghai, China

Science China Earth Sciences, 2021
The 2021 Qinghai Maduo MS7.4 earthquake was one of the strongest earthquakes that occurred in the Bayan Har block of the Tibetan Plateau during the past 30 years, which spatially filled in the gap of strong earthquake in the eastern section of the northern block boundary.

Testing a Prototype Earthquake Early Warning System: A Retrospective Study of the 2021 Mw 7.4 Maduo, Tibet, Earthquake

Seismological Research Letters, 2022
Abstract On 21 May 2021, an Mw 7.4 earthquake occurred in Maduo County, Qinghai Province, China. A dense network of high-rate (1 Hz) Global Navigation Satellite System (GNSS) stations around the epicenter provided one of the most complete recordings of GNSS kinematic displacements in Tibet to date.

Role of Poroelasticity and Viscoelasticity during the Postseismic Deformation of the 2021 Mw 7.4 Maduo, China, Earthquake

Seismological Research Letters, 2023
Abstract The 2021 Mw 7.4 Maduo earthquake within the Bayan Har block allows us to understand the lithospheric mechanical properties in northeastern Tibet. We analyze possible postseismic processes by modeling the six-month postseismic deformation from Interferometric Synthetic Aperture Radar data.

Stress and Strain Characteristics before the Mw 7.3 Maduo Earthquake and Its Implications for Future Earthquakes on the Maqin–Maqu Fault

Bulletin of the Seismological Society of America, 2022
ABSTRACT To determine the crustal deformation and the stress–strain accumulation characteristics preceding the Mw 7.3 Maduo earthquake and the seismic potential of the Maqin–Maqu fault segment, the seismic data from small earthquake events and Global Positioning System (GPS) observations stations are collected.

Study on the Heterogeneity of the Stress Field in the Maduo Earthquake Fault Zone

Seismological Research Letters
Abstract The 2021 Maduo earthquake sequence occurred on the Jiangcuo fault zone in Qinghai, China. However, the earthquake sequence did not occur along a straight fault. Aftershocks in the southeast section deflected the aftershocks in the southeast section to the east, when the aftershocks in the northwest section bifurcated.

Unveiling the Activity of a Young Fault: Insights from the 2021 Maduo Earthquake

Faults grow through fault lengthening and slip accumulation, which are episodic processes related to the repetition of earthquakes. It is most often recorded in geomorphology. Meanwhile, the activity and seismic hazard of the ‘slow-moving’ faults are often overlooked due to their weak imprints in landforms, especially at their ...

Shear-Wave Tomography and Cause of the 2021 Mw 7.4 Qinghai Maduo Earthquake

Seismological Research Letters
Abstract To better understand the cause of the 2021 Mw 7.4 Maduo earthquake in western China, we collect continuous waveforms recorded at 34 portable broadband MaduoArray seismic stations newly deployed from May 2021 to June 2023, as well as those from five permanent stations near the Maduo source area. Applying the ambient noise surface-

Temporal evolution of strain rate before the 2021 Mw 7.4 Maduo Earthquake. 

The development of geodetic tools, such as Interferometric Synthetic Aperture Radar (InSAR), has revolutionized our exploration of earthquake physics and the assessment of seismic hazard. Over the past 20 years, InSAR has been increasingly used to determine the interseismic strain rate across major seismogenic faults.

BEHAVIOR ANALYSIS OF YEMATAN BRIDGE ABUTMENT IN THE 2021 MADUO EARTHQUAKE AT QINGHAI, CHINA

On May 22, 2021, an M7.4 earthquake occurred in Maduo county, Qinghai, China, which caused significant damage to several bridges. Among them, the Yematan Bridge, a 25-span simply supported girder bridges experienced the most severe damage characterized by multi-span deck collapse and abutment failure. The abutment backwall fractured, departing from the
