The book contributes to understanding the mechanics of the Himalayan earthquake cycle. The motivation for active fault mapping of the Kumaun Sub Himalaya (it includes Garhwal and Kumaun regions of Uttarakhand) is to gain insight to the level of seismic hazard imposed by large earthquakes along the Himalayan arc. The book presents the compilation of knowledge garnered in multi-disciplinary or proxy studies involved in understanding of seismic hazard in general and Kumaun Himalaya region in particular with lucid new maps draped on modern Cartosat or SRTM DEM Data. It also discusses satellite image calibration, active faults identifications and map productions with flow chart. The book discusses window-wise active fault elements with attributes together with the tectonic geomorphic map. It also includes active fault scarp with topographic profile along with field photographs. Finally, it reviews all existing seismotectonic models of the Himalaya, its earthquake hazard and its vulnerability, specifically for Kumaun regions.
Recenzijas
The book can be a good teaching aid for active fault study, research on further paleoseismological investigations and adds another aspect in Tectonics of the Himalaya. (A.K. Jain, Journal of the Geological Society of India, Vol. 93, 2019)

Dr. R. Jayangondaperumal is a Senior Scientist in the Wadia Institute of Himalayan Geology, Dehradun. He has been working in research projects related to structural geology, earthquake geology, and tectonics for over one and a half decade. Dr. Perumal and his team have excavated about 25 trenches for paleoseismological study along the Himalayan frontal zone. He has significantly contributed in understanding the relationship between strain accumulation and release in context of mechanics of earthquakes and mountain building processes so as to quantify the seismic hazard associated with the Himalayan continental collision. He has also carried out seismic hazard assessment for the Subansiri hydro-power project in the NE Himalaya. He has published over 46 papers, and contributed two book chapters and one Indian Patent. Currently, he along with his large team of students carrying out national level research projects on earthquake geology in NE and NW Himalaya.
Dr. Vikram C. Thakur is M.Sc. Panjab, and Ph.D. DIC London University. He joined the Wadia Institute of Himalayan Geology in 1972. He has worked extensively in unravelling the regional framework and tectonics of the remote regions of Ladakh, Zanskar, Chamba, Garhwal, Kumaun, and Arunachal. On his retirement as Director of the Institute he was awarded Emeritus Scientist of the CSIR, since then he has been working in several research projects on active tectonics of the Himalayan frontal zone. He has published more about 130 papers and authored a book Geology of Western Himalaya, Pergamon Press, Oxford. He is a fellow of the Indian Academy of Sciences (1991) and recipient of the National Mineral Award (1984).
Dr. V. Joevivek is a Professor and Dean (Research) at Akshaya College of Engineering and Technology, Coimbatore. His field of specialisation is remote sensing and physical geography.
