Earthquake Seismology presents the most recent findings on the physics of earthquakes. It includes chapters on seismicity studies from pre-historic periods to the most modern studies on a global scale, deep earthquakes, nucleation, stress transfer, triggering, hydrological processes, and recently discovered slow slips at plate boundaries. It also covers closely related fields including tsunami, volcanic seismology and physics, interaction between solid earth, atmosphere and ionosphere. Discussions on strong-motion seismology and its social implications are also reviewed.Self-contained volume starts with an overview of the subject then explores each topic with in depth detailExtensive reference lists and cross references with other volumes to facilitate further researchFull-color figures and tables support the text and aid in understandingContent suited for both the expert and non-expert

Near-Fault Seismic Ground Motions

Author: Dreger, Douglas S., Hurtado, Gabriel, Chopra, Anil K., Larsen, Shawn C. | Size: 3.9 MB | Format: PDF
Bridges that cross faults are subject to static deformation that occurs at almost the same time as the arrival of dynamic pulse-like ground motions. Static offsets can be as large as several centimeters to many meters and strong ground motion velocity pulses exceeding 100 cm/s have been observed. Near-fault records, in the distance range of 10 to 100s of meters from faults are essentially nonexistent except for a few cases and therefore numerical simulation of ground motions for such near-fault situations is necessary. The paper presents simulated ground motions to 17.5 Hz, 15-100m from the fault for a Mw6.5 earthquake using an elastic finite-difference code. Simulations for homogeneous earth structure are compared for uniform and heterogeneous fault rupture scenarios. To investigate asymmetry of ground motions on opposite sides of a dipping reverse fault the dislocation method of Okada (1992) is used to compute static offset. From those results a simplified procedure for the simulation of near-fault time histories is developed. All of the simulations assume linear elasticity, and it is noted that the computed strain is as high as 10-4 - 10-3, and it is likely that there would be significant non-linear behavior in this near-fault region.

why-we-cant-predict-Earthquakes

یک کارشناس ارشد مسائل بحران و زمین لرزه گفت: از میلیون‌ها زلزله‌ کوچک و بزرگ، تعداد زلزله‌هایی که بشر توانسته قبل از وقوع با پیش بینی اجمالی از تلفات آن بکاهد به تعداد انگشتان دست هم نمی رسد.

این یک حقیقت تلخ است ولی واقعا چرا زلزله قابل پیش بینی نیست
