Active Geophysical Monitoring

Active Geophysical Monitoring, Second Edition, presents a key method for studying time-evolving structures and states in the tectonically active Earth's lithosphere. Based on repeated time-lapse observations and interpretation of rock-induced changes in geophysical fields periodically excited by controlled sources, active geophysical monitoring can be applied to a variety of fields in geophysics, from exploration, to seismology and disaster mitigation. This revised edition presents the results of strategic systematic development and the application of new technologies. It demonstrates the impact of active monitoring on solid Earth geophysics, also delving into key topics, such as carbon capture and storage, geodesy, and new technological tools.

This book is an essential for graduate students, researchers and practitioners across geophysics.

• Outlines the general concepts of active geophysical monitoring with powerful seismic vibrators and MHD generators
• Provides historical background for previous studies of seismically active zones
• Covers the theory and technology of active monitoring, including signal processing, data analysis, novel approaches to numerical modeling, and interpretation
• Discusses case histories and presents the results of worldwide, regional active monitoring experiments
• Thoroughly updated to include recent developments, such as updates relating to carbon capture and storage, microgravity, InSAR technologies, geodesy, reservoir monitoring, seismic reflection, and more

Hitoshi Mikada was a professor and is now an emeritus professor at Kyoto University, Japan. He received both M.S. and D.Sc. degrees in geophysics from the University of Tokyo in 1983 and 1994, respectively. He started his professional career as an interpretation engineer in the petroleum industry. In 1991, he started his academic career as a research associate at the Volcano Research Center of the Earthquake Research Institute of the University of Tokyo and as a senior scientist in the Deep-Sea Research Department of Japan Agency for Marine-Earth Science and Technology (JAMSTEC) from 1999 to 2004. In 2004, he moved to Kyoto University to become in charge of the geophysics laboratory. His main interests include research on theories and praxis in seismic scattering, wave propagation in attenuating and anisotropic media, seismic data processing,
electromagnetic exploration, geophysical logging, etc.

Professor Zhdanov is a full member of the Russian Academy of Natural Sciences, a fellow of the Electromagnetics Academy, USA, and a senior member of IEEE. He received one of the highest awards of the International Society of Exploration Geophysicists, an honorary membership award, in recognition of his distinguished contributions to exploration geophysics and to the advancement of the profession.

Junzo Kasahara received B.S., M.S., and D.Sc. degrees in geophysics from Nagoya University in 1965, 1967, and 1970, respectively. From 1970 to
1986, and then from 1988 to 2004, he was an assistant, associate, and full professor at the University of Tokyo. He worked in marine seismology. During 1974, 1976, and 1979, he was a visiting associate professor at the University of Hawaii. In 1986, he joined Schlumberger Japan as a manager for seismic interpretation and logging tool design. During his academic work, he published three books with the University of Tokyo Press. He was awarded the title of professor emeritus at the University of Tokyo. In 2004, he joined the Tono Geoscience Center as a senior researcher, where he worked on the ACROSS project. Between 2004 and 2008, he served for the extension of the Japan Continental Shelf. Currently, he is the principal
investigator of the geothermal project and a visiting professor at the University of Shizuoka.
