This document was produced to accompany the Teachable Moment resources for Haiti produced by IRIS University of Portland Introduction The two most important variables affecting earthquake damage are (1) intensity ground shaking caused the quake coupled with (2) quality engineering of structures in region The level shaking, turn, is controlled proximity source to affected types rocks that seismic waves pass through en route (particularly those at or near surface) Generally, bigger, closer, shallower earthquake, stronger But there have been large earthquakes very little damage either because they populated areas, buildings were built withstand kind In other cases, moderate caused significant because was locally amplified, more likely structures poorly engineered Damage during an results from several factors Strength strong a magnitude 7 becomes half as at a distance 8 miles, quarter 17 eighth distance 30 sixteenth 50 miles Length Length depends on how fault breaks maximum shaking Loma Prieta lasted only 10 15 seconds During earthquakes Bay Area, may last 30 40 longer shake, greater Type soil Shaking is increased soft, thick, wet soils In certain surface settle slide building Certain buildings, discussed in reducing section, not resistant enough side common Resonant frequency See page 3 From USGS http: usgs gov prepare future Activities pages 4 5 (touch go there) Haiti Devastation Exposes Shoddy Construction see next text link video!!!! towerpdf what earthquake earthquake causes earthquake effects how happen earthquake information types earthquakes earthquake definition earthquake causes effects الهندسة المدنية مجاناً PDF اونلاين قسم خاص بكتب للتحميل مجال وهي أحد فروع والمعنية بدراسة وتصميم وتحليل المنشآت المختلفة كالأبنية السكنية والخدمية والطرق والجسور والأنفاق والمطارات والموانئ وشبكات إمداد مياه الشرب ومحطات ضخ المياه الصرف الصحي التنقية ومعالجة والسدود وكذلك مشاريع الري والإشراف عمل هذا أثناء فترة استمرارها لذا لا يجوز حصر العلم بأنه المعني بالتصميم وحده فقط وهي كأي علم تتطور باستمرار ودون توقف وفي الآونة الحديثة ترابطت مع التطور الصناعي بشكل كبير لإنتاج مواد إنشائية جديدة ومتطورة تفي بالمتطلبات التي تكون دائما متزايدة من المجتمع A special section books civil one branches concerned studying, designing analyzing various installations such residential service roads, bridges, tunnels, airports, ports, drinking water supply networks, pumping stations, sewage purification treatment dams, well irrigation projects, supervising work this Establishments period their continuation, so it not permissible limit flag design alone
