Preface for the Special Issue of 2000 International Conference for CT & 3D Imaging, Beijing

In the last 20-years, CT theory and applications in medical diagnosis have developed fast in Asia &China, and extended into the fields of seismology, geophysics, bio-medicine, industry and engineering,and got a lot of achievements and beneficial results. A lot of academic worldwide exchanges of CT theoryand application are important for human. Hence, we have gotten the corresponding official permissiondocument from China Ministry of Science and Technology and China Association for Science…     

Preface to the Special Issue on Earthquake-Induced Landslides

正Earthquake-induced landslides are the most destructive secondary geological hazards following large earthquakes that can destroy infrastructures and cause loss of lives and properties (Marano K.D.et al.,2010;Xu Chong et al.,2018).In the past few decades,earthquake-induced landslides have captured growing interests of both scientific communities

Preface to the special issue on Lushan earthquake

On April 20th, 2013, a strong earthquake （Ms7, China Earthquake Network Center） struck Lushan county of Sichuan province and the quake （hereafter referred to as Lushan earthquake） caused substantial loss of life and damage to infrastructure. Just as the 2008 Ms8 Wenchuan earthquake, the Lushan earthquake also occurred on the Longmenshan fault system. After the Lushan earthquake, preliminary studies of the Lushan earthquake and its pos- sible link to the Wenchuan earthquake have been published in special issues rapidly organized in a few journals such as Seismological Research Letters, Chinese Journal of Geo- physics and Science in China.     

《卫星地震应用研究》专辑前言

正我国的卫星地震应用研究最早始于20世纪70年代中期.国家地震局地震研究所和国家地震局地质研究所(1982)基于美国陆地资源卫星MSS的遥感图像,开展了全国范围的活动构造调查工作,基本查明了我国的主要活动构造及其分布情况.经过多年的发展,兵马未动,遥感先行,这已经成为目前地震构造研究的基本工作方法.20世纪80年代后期,遥感技术的快速发展带来了现代地壳运动和地震监测技术的创     

Preface to the Special Issue on Active Source Research

<正>The seismic waveforms may present subtle changes related to the external loadings such as earthquakes (Pei Shunping et al.,2019) and landslides (Larose E. et al.,2015). Monitoring subtle changes provides a complementary tool for studying the dynamic processes (e. g.,Niu Fenglin et al.,2008),which has long been a major subject in seismology.The subsurface can be monitored by using natural repetitive events including repeated earthquakes (e.g.,Song Xiaodong et al.,1996) and ambient seismic noises (e.g.,Mao Shujuan et al.,2019). However,only the use of repeatable active sources can achieve long-distance and     

Preface to the special issue on ambient noise seismology

<正>Not too long ago,seismic imaging of the Earth’s interior relied almost exclusively on the illuminationfrom energetic sources,such as earthquakes or artificialsources. However,recent theoretical and laboratory stu-dies have shown that the impulse response (Green’sfunction) of a structure between two receivers can be
