This paper presents the first release of an Informational System(IS)devoted to the systematic collection of all available data relating to Pliocene-Quaternary faults in southern East Siberia,their critical analysis and their seismotectonic parameterization.The final goal of this project is to form a new base for improving the assessment of seismic hazard and other natural processes associated with crustal deformation.The presented IS has been exploited to create a relational database of active and conditionally active faults in southern East Siberia(between 100°-114° E and 50°-57° N)whose central sector is characterized by the highly seismic Baikal rift zone.The information within the database for each fault segment is organized as distinct but intercorrelated sections(tables,texts and pictures,etc.)and can be easily visualized as HTML pages in offline browsing.The preliminary version of the database distributed free on disk already highlights the general fault pattern showing that the Holocene and historical activity is quite uniform and dominated by NE-SW and nearly E-W trending faults;the former with a prevailing dip-slip normal kinematics,while the latter structures are left-lateral strike-slip and oblique-slip(with different proportion of left-lateral and normal fault slip components).These faults are mainly concentrated along the borders of the rift basins and are the main sources of moderate-to-strong(M≥5.5)earthquakes on the southern sectors of East Siberia in recent times.As a whole,based on analyzing the diverse fault kinematics and their variable spatial distribution with respect to the overall pattern of the tectonic structures formed and/or activated during the late Pliocene-Quaternary,we conclude they were generated under a regional stress field mainly characterized by a relatively uniform NW-SE tension,but strongly influenced by the irregular hard boundary of the old Siberian craton.The obtained inferences are in an agreement with the existing models of the development of 相似文献

全国地质资料馆网站访问分析 总被引:2,自引:0,他引:2
通过万瑞数据TM互联网全数据整合应用平台,对全国地质资料馆网站在2009年8月5日0时至9月4日24时之间的独立用户数、页面浏览量、访问次数、访问深度、访问频率、平均访问停留时长6个指标进行了统计分析。研究发现,网站访问者主要为专业人员,用户来自以北京为主的国内33个省(自治区、直辖市)和以美国为主的12个国家;网站的页面浏览量虽少,但访问深度和停留时长较强,用户的粘性较好,远大于媒体型网站的用户访问粘度。网站存在访问人员数量较少、关键词专业性强、用户分布不均衡、网站内容更新不及时等问题。建议网站采取适时更新内容、创新表现形式、加强宣传等措施,以吸引更多的用户访问。 相似文献

随着Internet的普及,各种网站如雨后春笋般的出现,并为个人主页提供免费空间。于是,许多爱好者就在上面制作了个人主页,可是要访问后台数据库,却是一个复杂的过程,令不少人望而却步。本文介绍一种简单的方法来实现对后台数据库的访问。客户利用浏览器填写表单,发出请求给服务器,经过服务器的处理,以HTML格式返回给客户结果,其原理见图1。在这里用到了Microsoft提供的数据库连接器IDC,文件名为httpodbc.dll。数据库连接器要求32位的ODBC驱动程序,其目的是应用程序使用标准的结构化查询语言SQL命令,通过ODBC驱动程序,访… 相似文献
