Scientific Rationale and Requirements for a Global Seismic Network on Mars [PDF]

open access: yes, 1991
Following a brief overview of the mission concepts for a Mars Global Network Mission as of the time of the workshop, we present the principal scientific objectives to be achieved by a Mars seismic network.

Depth-varying rupture properties of subduction zone megathrust faults [PDF]

open access: yes, 2012
Subduction zone plate boundary megathrust faults accommodate relative plate motions with spatially varying sliding behavior. The 2004 Sumatra-Andaman (M_w 9.2), 2010 Chile (Mw 8.8), and 2011 Tohoku (M_w 9.0) great earthquakes had similar depth variations

Geotechnical design with apparent seismic safety factors well-bellow 1 [PDF]

open access: yes, 2014
The paper demonstrates that whereas often in seismic geotechnical design it is not realistically feasible to design with ample factor of safety against failure as is done in static design, an "engineering" apparent seismic factor of safety less than 1 ...

麦宿断裂地震地表破裂带的发震构造分析

open access: yesDizhen xuebao
野外地质调查发现金沙江断裂带北段麦宿断裂附近发育长约50 km的地震地表破裂带,其最大垂直位移为2 m。基于该地震地表破裂带周围架设的密集地震台阵于2020 年 12 月至 2022 年 7 月期间记录到的连续波形数据,采用双差定位方法对(31.55°N—31.85°N,98.31°E—98.98°E) 区域内的578个地震事件进行定位,并利用基于P波初动的HASH方法对定位得到的地震事件进行震源机制解反演,获得了37组震源机制解 ...

Evidence for postseismic deformation of the lower crust following the 2004 Mw6.0 Parkfield earthquake [PDF]

open access: yes, 2011
Previous studies have shown that postseismic relaxation following the 2004 Mw6.0 Parkfield, CA, earthquake is dominated by afterslip. However, we show that some fraction of the afterslip inferred from kinematic inversion to have occurred immediately ...

Geodetic Observations and Seismogenic Structures of the 2025 Mw 7.0 Dingri Earthquake: The Largest Normal Faulting Event in the Southern Tibet Rift

open access: yesRemote Sensing
The Mw 7.0 Dingri earthquake, which occurred on 7 January 2025, occurred at the southern end of the Xainza-Dinggyê Fault Zone within the South Tibet Rift (STR) system, in the Dengmecuo graben.

Interpretation of the west segment of the coastal fault zone in the coastal region of South China based on the gravity data

open access: yesGeodesy and Geodynamics, 2018
By systemic processing, comprehensive analysis, and interpretation of gravity data, we confirmed the existence of the west segment of the coastal fault zone (west of Yangjiang to Beibu Bay) in the coastal region of South China.

Earthquakes: from chemical alteration to mechanical rupture

open access: yes, 1998
In the standard rebound theory of earthquakes, elastic deformation energy is progressively stored in the crust until a threshold is reached at which it is suddenly released in an earthquake.
