Constraint on the focal mechanism of the 2011 Tohoku earthquake from the radial modes
Geodesy and GeodynamicsDifferent from other normal modes of the Earth's free oscillation that depend on all the six components (Mrr, Mtt, Mpp, Mrt, Mrp, and Mtp) of the centroid moment tensor, the amplitudes of the radial modes depend on the Mrr component (e.g., scalar moment (

Dizhen xuebao, 2022 基于搜集到的2000—2018年滇西北地区MS≥3.0地震的震源机制解，运用线性叠加反演法进行应力场反演，分析了滇西北地区现今的构造应力状态，进一步探讨了应力张量方差的时空分布与地震活动的关系。结果显示：① 滇西北地区地震的震源机制解类型复杂，主要以走滑型（46%）为主，正断型（27%）次之；② 研究区的构造应力场具有整体的一致性和局部的非均匀性，呈现为NNW向挤压和ENE向拉张的走滑型应力结构，说明研究区受到来自NNW向的水平挤压作用，对该地区上地壳运动和断裂活动起主导作用；③ ...
