Book "Tsunami on Sakhalin Island: Observations and Numerical Modeling" by A. and . Zaitseva, I. C. Kostenko, A. A. Kurkina and E. N. Pelinovsky is a unique scientific study that immerses the reader in the complex and exciting world of natural disasters. This work is intended for those who are interested in seismology, hydrodynamics, geophysics and natural threats, as well as for specialists, students and a wide range of inquisitive readers seeking to understand the mechanisms of the emergence and spread of tsunamis in the region of the Far East of Russia. The book reveals to the reader not only the theoretical foundations of the tsunami, but also offers a practical view of the problem, based on observations and modern numerical models. The authors carefully analyze the historical cases of tsunamis that occurred in the Sakhalin region, and use advanced mathematical modeling methods to predict possible scenarios for the development of events. As a result, the reader receives not only a scientific description of the phenomenon, but also a practical guide to risk assessment and preparation for possible natural disasters. The book pays special attention to the Sakhalin region, one of the most vulnerable areas of the Pacific Ring of Fire for the tsunami. Here, the authors consider geological features, seismic activity and historical data, creating a complete picture of the threat. This makes the book a valuable resource for conservationists, meteorologists, rescue services and public authorities responsible for public safety. What makes “Tsunami on Sakhalin Island: Observations and Numerical Modeling” especially attractive is the combination of scientific rigor and accessibility of presentation. The authors skillfully balance between complex mathematics and understandable language, which allows even an unprepared reader to understand the basic principles of modeling and the importance of timely response to natural threats. The style of presentation is full of living examples, illustrations and graphs, which makes reading not only informative, but also fascinating. The book is perfect for students and graduate students studying geophysics, geography and ecology, as well as for specialists engaged in monitoring natural disasters and developing warning systems. In addition, it may be of interest to a wide audience who wants to expand their knowledge of natural disasters and understand how modern technologies help predict and minimize the consequences of the tsunami. The author’s team, including leading scientists in the field of seismology and hydrodynamics, has created a work that not only enriches the scientific community with new data and models, but also raises important questions about the need to strengthen measures to prepare for and respond to natural disasters. The book vividly traces a special style of authors - a combination of strict scientific analytics with a lively, fascinating presentation, which makes it accessible and interesting for a wide audience. If you are looking for a book that will help you understand how tsunamis form, what threats they pose to Sakhalin and other regions of the Pacific region, as well as how modern modeling methods help predict their development, - "Tsunami on Sakhalin Island: Observation and Numerical Modeling" will become an indispensable source of knowledge for you. This book is an important contribution to the development of the science of natural disasters and a reliable tool for improving the safety of the population in risk zones.
