Earthquakes happen as large blocks of the Earth's crust move past one another as a consequence of the force between plate tectonics. These blocks of the Earth's crust meet at cracks called faults. While the edges of faults are stuck together, and the rest of the block is moving, the energy that would normally cause the blocks to slide past one another is being stored up. When the force of the moving blocks finally overcomes. The friction of the jagged edges of the fault and it unsticks, all the stored up energy is released. The energy radiates outward from the fault in all directions in the form os seismic waves. The seismic waves shake the earth as they move through it. The size of an earthquake depends on the size of the fault and the amount of slip on the fault, but that's not something that can be measure in a simply way. The extensions of the faults are many kilometers deep beneath the earth's surface. So to measure an earthquake it is use the seismogram recordings made on the seismographs at the surface of the earth determine how large the earthquake was. Each year, more than a million earthquakes happen worldwide. Although most of these are small enough so that people do not feel the shaking, some are large enough that they cause significant damage. In this book we cover some aspects of the complicated science behind earthquakes, their basics, how are the measure, it is possible to forecast?
This book presents a brief introduction and partial overview of active fold growth that deforms the surface of the Earth. It is a subject that provides a direct interface between structural geology, earthquake geology, surface processes and tectonic geodesy. The book aims to educate the readers with information regarding the field of earthquake engineering. The mitigation of earthquake-related hazards is essential in the modern society. The mitigation of such kind of hazards extends from detailed studies on seismicity, assessment of sites affected and seismo-induced landslides. It also expands from analysis of disasters like tsunami along with the design and analysis of structures to refrain such actions. The study of earthquakes integrates science, technology and expertise in infrastructure and engineering in an endeavor to curtail human and material losses due to earthquakes. This book deals with a variety of topics aiming to mitigate geo-hazards like seismic hazard analysis, ground investigation for seismic design, seismic design, assessment and remediation, earthquake site response evaluation and soil-structure interaction assessment.
