As revealed by field investigations,the co-seismic surface rupture zone of the 2010 MS7.1 Yushu earthquake,Qinghai is a characteristic sinistral strike-slip feature consisting of three distinct sinist
春。五月。又见英雄的五月。如果说两年前5.12汶川地震的关键词是"猪坚强",那么今年,是花坚强,是花在"亮剑"。请把眼界打开,放眼望去——冬寒去尽,京城那些花期被逶迤推迟的繁花争相吐艳,三月的桃花、梨花、丁香花、迎春花与五月的海棠花争艳落成花海,四月的杨花把这个五月装扮成"雪"的世界……这个五月整合了整整一个春天的资源。把美丽尽情地回报人间。而青海玉树地震也是如此,据本期封面人物赵健英介绍,玉树地
Na+ ions play an important role in the growth of halophyte. The effect of Na+ ions on nitrate uptake and osmotic adjustment in the euhalophyte Suaeda physophora was investigated under glasshouse condi
Fourier spectra and acceleration response spectra of near-field acceleration records of the 2008 Wenchuan Earthquake have been calculated.Relative fundamental frequencies(or predominant periods) were
Passive image interferometry (PII) is becoming a powerful tool for detecting the temporal variations in the Earths structure,which applies coda wave interferometry to the waveforms from the cross-corr
Long-time cross correlation of ambient noise has been proved as a powerful tool to extract Greens function between two receivers.The study of composition of ambient noise is important for a better und
We present a new approach to polarization analysis of seismic noise recorded by three-component seismometers.It is based on statistical analysis of frequency-dependent particle motion properties deter
We determine the three-dimensional shear wave velocity structure of the crust and upper mantle in China using Greens functions obtained from seismic ambient noise cross-correlation.The data we use are
We apply ambient noise tomography to significant seismic data resources in a region including the northeastern Tibetan plateau,the Ordos block and the Sichuan basin.The seismic data come from about 16
为了促进有效减灾,为可持续发展战略服务,拟以《防灾减灾工程学报》为交流平台,以《学报》编委会为学术依托,发起组织召集"全国防灾减灾工程学术系列研讨会",会议立足于交流近年来我国防灾减灾工程领域里的最新研究成果,推动理论在工程实践中的应用,为我国人居和重大工程提供安全环境而努力。
