四川泸定 地震震源破裂过程 反演初步结果
2023/1/16
北京时间2022年9月5日12点52分 (UTC 2022-9-5 04:52:20) 在我国四川省泸定县发生了M6.8级地震。地震发生后，我们从IRIS数据中心下载了地震数据资料用于研究地震震源机制和震源破裂过程。选取其中信噪比较高并且沿方位角分布比较均匀的19个远场P波波形（震中距位于30°<△<90°范围之内）和21个SH波波形资料进行点源模型的震源机制解反演；根据反演结果构建有限断层模型进...
By examining earthquake models from a fresh perspective, Cornell engineers now show that the earthquake fracture energy – once thought to relate to how faults in the Earth’s crust weaken – is related ...
Major environmental events write their own headlines. With loss of life and crippling infrastructure damage, the aftershocks of earthquakes reverberate around the world — not only as seismic waves, bu...
