Applied geophysics is concerned with the implementation of geophysical theories and concepts to practical problems and tasks of civil engineering such as groundwater mapping, ore and mineral prospecting, etc. It studies physical phenomena like magnetism, electricity, radioactivity, etc. It also encompasses geological concepts to understand and analyze dynamics of plate tectonics, volcanism, rock formation, Earth's gravitational and magnetic fields, etc. The principles of applied geophysics are also significant to a number of prominent disciplines such as Earth systems science, climatology, earthquake research, etc. This book is compiled to provide in-depth knowledge about the theory and practice of geophysics. It strives to provide a fair idea about this discipline and to help develop a better understanding of the latest advances within this field. The content included herein is appropriate for students seeking detailed information in this area as well as for experts.
