This book details both conventional and advanced geophysical techniques with description of the Electromagnetic (EM) based physics involved in different methodologies of magnetotellurics (MT). It offers detailed discussions of the theory of EM and MT methods, and the operation of specific instruments, including the presentation of results and their interpretation in tabular format. The chapters describe the conceptual background of MT geophysical methods along with the related instrumentation, sufficient illustrations, and the applicability of the individual methodologies supported by successful case histories.

Features:

Provides a comprehensive introduction to the MT–geophysical method. Covers diverse geotectonic settings with several case studies, supported by diagrams and data tables. Describes the fundamentals of uncontrollable telluric and controllable non-telluric sources used in MT surveys. Reviews MT methods with emphasis on recent improvements, recognizing both static and distortion effects and their treatment in the analysis of impedance tensors in 3-D inversion codes. Explores integrated MT interpretation coupled with seismic and potential (gravity, magnetic) geophysical methods.

This book is aimed at professionals, students, and researchers in geophysics, geology, civil, mechanical, petroleum, and geothermal engineering, and other branches of earth and environmental sciences.

O.P. Mishra is a Fellow of the National Academy of Sciences, India (F.N.A.Sc.), for his pioneering work involving applied geophysics/seismology/disaster risk management, with over 30 years of experience in different fields of earth sciences and seismology. He obtained an M.Sc. Tech degree from IIT (ISM)-Dhanbad in applied geophysics; a Ph.D. and a D.Sc. from the Geodynamics Research Centre, Ehime University, Japan, in seismology; a postgraduate diploma in management (PGDMA) from the Centre for Education of the All India Management Association (AIMA), New Delhi, the apex body of the Indian Institutes of Management (IIMs). specializating in finance management. D.C. Naskar received an M.Sc. in physics from Calcutta University. He was conferred with a doctorate degrees from Jadavpur University. He worked for three and a half years as an assistant teacher in physics in a West Bengal Government Aided HS School. He also worked at the West Bengal State Electricity Board in Santaldih, Purulia, West Bengal, and as a chemical and metallurgical assistant for South Eastern Railway in Waltair, Andhra Pradesh, prior to joining in GSI. He joined GSI in July 1989. Dr. D.C. Naskar has held the position of director (geophysics) at the Geological Survey of India (GSI). He has over 32 years of experience in geophysical mapping, employing gravity, magnetic, deep resistivity, GPS, and magnetotelluric (MT), and seismic techniques across various regions of the Geological Survey of India (GSI).
