Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.Abstract Seismic attenuation, resulting from anelasticity of Earth's materials, provides critical information on the thermal and compositional characteristics of Earth's interior. Accurately measuring the seismic wave energy loss during propagation and conducting seismic attenuation is challenging, as conventional methods for measuring attenuation ...

Monitoring earthquakes with gravity meters
Geodesy and Geodynamics, 2011 Seismic waves from a magnitude 8.3 earthquake in Japan were consistently recorded by five nearly identical gPhone gravity meters in Colorado. Good correlation was also found in the response of two different types of gravity meters and a standard ...

Structure of the North‐Central Chile Subduction Zone From Local Earthquake Tomography
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.Abstract The fluid cycle in subduction zones prescribes large parts of its structure and seismogenic behavior. Background seismicity inside the downgoing slab is linked to fluid release from dehydration reactions, whereas fluid overpressure along the plate interface can alter interplate coupling, megathrust earthquakes, and the presence or absence of ...

Dizhen xuebao现代地震研究依赖于可靠的三分量观测数据，地震计的北分量是否严格指北将直接影响研究的准确性。然而，受台站附近磁异常或人为安装错误的影响，地震计的方位角可能出现偏差。基于东北地区154个固定台站2020年的远震数据，利用P波质点运动方法，估算了每个台站的北向分量方位角，以判断台站地震计是否存在方位角偏转问题。结果表明，84%的台站运行良好，12%的台站存在方位角偏差绝对值过大（＞20°）或分量极性反转等问题。此外，分析后发现方位角偏转较大会导致H-κ叠加方法计算得到的地壳厚度和地震波速比出现偏差。因此 ...
