Dizhen xuebao, 2022 2022年1月8日青海境内的托莱山—冷龙岭断裂附近发生了门源MS6.9地震。结合地壳厚度、速度结构及各向异性等资料探讨了门源地震的深部构造特征，揭示了门源地震的发震位置与地壳结构变化的密切关联。结果显示：门源MS6.9地震发生在地壳厚度和vP/vS值都出现快速空间变化的区域；大约在10—20 km深度范围内，震源位于P波速度从浅到深由高速变低速的垂向过渡区，同时也是S波速度和泊松比分布呈现明显横向变化的过渡区域，震源下方存在明显的低速区；冷龙岭断裂两侧相速度的方位各向异性变化比较明显。1月12日的MS5.

An earthquake response spectrum method for linear light secondary substructures [PDF]
, 2007 YesEarthquake response spectrum is the most popular tool in the seismic analysis and design of structures. In the case of combined primary-secondary (P-S) systems, the response of the supporting P substructure is generally evaluated without considering ...
