This book presents the frontiers of tsunami science and research and demonstrates the unprecedented progress achieved during this period overviewing different aspect of tsunami science including meteorological tsunamis. The two 1992 events near Nicaragua and Flores Island, Indonesia, marked the beginning of a "modern tsunami science era" producing highly destructive tsunamis and opened a 25-year period of numerous devastating events, including two of the most destructive natural disasters in recent human history: the 26 December 2004 Sumatra and the 11 March 2011 Tohoku tsunamis. The book is of interest to scientists and practitioners as well postgraduate students in geophysics, oceanography and coastal engineering, involved in all aspects of tsunamis, from earthquake source processes to transoceanic wave propagation, from coastal impacts to hazard assessment and combining recent case studies with advances in tsunami science and natural hazards mitigation.
