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.     

Preface to special issue on progress of computational seismology

正Seismology had emerged as a discipline of modern science during the last century through an extensive interplay between theoretical and experimental seismological researchers(Aki and Richards,2002).Today,     

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     

《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 the 2008 great Wenchuan earthquake

On 12 May 2008, about one year ago, a devastating earthquake (MS8.0, MW7.9) struck the eastern margin of the Tibetan plateau in west China, its vast energy swept     

Preface to the special issue on seismic array analysis and CEArray

A seismic array is a set of seismographs being arranged in a regular geometric pattern to improve signalto-noise ratio (SNR).Seismic arrays at various length scales have been introduced since early 1960s and have been proved to be superior to single three-component stations for detecting and characterizing signals from earthquakes and explosions.     

Preface to special issue on recent advances in computational seismology and its applications

正Computational seismology is a relatively new interdisciplinary field spanning computational techniques in theoretical and observational seismology. It studies numerical methods and their implementation in various theoretical and applied problems in seismology. It emerged as a branch of modern seismology in the 1950s when digital computers were introduced into the study of     

《强地震动模拟及工程应用专辑》前言

强地震动模拟分析涉及地震学、岩石力学、土动力学等多个学科,是工程地震学的核心内容之一,国内外学者在该领域已取得较多重要进展.近年来,随着国家韧性城乡建设的需要,区域复杂场地地震区划及重大工程建设对地震动场的准确模拟提出了更高要求.综合考虑震源、路径和场地效应的区域尺度地震动模拟以及场地-结构(群)地震相互作用等已成为当...     

Preface to the special issue on complicated features on seismic sources and deep structures

Earthquake is a kind of natural phenomenon in the Earth.Earthquake seismology has been developed quickly since modern digital seismometers were applied to observations.From seismic records,seismologists study source properties of the earthquakes and detect multi-scale structural variations in the crust,mantle,and core.     

《与地震有关的电磁现象及其机理 和观测研究专辑》前言

<正>地震电磁学在地震预测研究领域占有重要位置.长期观测研究表明,在地震发生前会出现许多电磁异常现象.多年来,国内外学者利用这些异常信息开展了地震预测探索研究.自20世纪以来,地震电磁异常现象越来越引起人们的兴趣和重视,绝大多数强烈地震都有临震异常现象的发现与记载.到目前为止,国内外学者对地震前电磁异常现象与地震的关系进行了许多观测、实验和研究,积累了十分宝贵的经验和资料,为人们认识地震前电磁异常的现象提供了越来越丰富的震例.
