The prediction of the earthquake ground motion has always been of primary interest to seismologists and structural engineers. Large earthquakes that have occurred in densely populated areas of the world in recent years (eg Izmit, Turkey, August 17, 1999; Duzce, Turkey, November 12, 1999; Chi-Chi, Taiwan, September 20, 1999; Bhuj, India, January 26, 2001; Sumatra, Indonesia, December 26, 2004; Wenchuan, China, May 12, 2008; L’Aquila, Italy, April 6, 2009; Haiti, January 2010; Turkey 2011) highlight the dramatic inadequacy of a massive portion of the buildings erected in and around the epicentral areas. It has been observed that many houses were unable to withstand the ground shaking. Building earthquake-resistant structures and retrofitting old buildings on a national scale can be extremely expensive and can represent an economic challenge even for developed Western countries. Planning and design should be based on available national hazard maps which, in turn, must be produced after a careful calibration of ground motion predictive relationships for the region, estimation of seismic site effects as well as studies for the characterization of seismicity, seismogenic sources etc. Updating existing hazard maps represents one of the highest priorities for seismologists who contribute by refining the ground motion scaling relations and reducing the related uncertainties. The chapters in this book are devoted to various aspects of earthquake research and analysis, from theoretical advances to practical applications. Chapters one to four are dedicated to ground motion studies, spanning the seismic source characterization to estimation of ground motion parameters. Chapters in the site characterization section tackle the significance of the local seismic response. This topic is of increasing importance in earthquake seismology and in the seismic microzonation since regional geology can have a large effect on the characteristics of ground motion. The site response of the ground motion may vary in different locations of the city according to the local geology. Some chapters are dedicated to seismic hazard and early warning systems. The final chapter presents a study in investigating land mass movements. Such studies could be integrated with the seismic hazard estimation and microzonation since ground deformations, along with severe shaking, could also be responsible for the devastation.
