We live in the 21st century. The satellites cruising around the earth help our daily communication. The spacecrafts travel interplanetary space to collect information. Radio telescopes watch birth and death of stars. We try to understand what happened in the galaxies millions of light years away. Yet we cannot see what is behind the wall next to us or what is under our feet.
Geophysics is a tool to “see” the invisible. Any physical phenomenon provides hints to geophysics: vibration, sound, mass, electric and magnetic properties, heat, radiation, and cosmic rays as much as our imagination could lead us. With a clear understanding of the phenomenon, we can predict what is in the invisible space. With appropriate instrumentation, we can prove it. With the wildest imagination, we can develop ways to “see the invisible.” Geophysicists study the natural phenomena to understand the system. Some geophysicists design instruments right for observing the phenomena and some geophysicists interpret the data to “see” the invisible. Geophysics is a fun subject. It offers you a lot of challenge and a lot of reward.
This presentation guides you around the fascinating world of geophysics.
Koya Suto received bachelor’s and master’s degrees in exploration geophysics from Mining College, Akita University, and studied further at the University of Adelaide. Born in Japan, Suto first studied gravity, airborne magnetics, and radiometrics for geologic mapping and mineral exploration. He worked for the petroleum industry as a seismic geophysicist for 25 years.
Koya started Terra Australis Geophysica in 2003 to service the civil engineering and environmental industries with near-surface geophysical surveys using the surface wave seismic (MASW) method. Since then, he has presented a number of case histories of MASW surveys in international conferences.
He served as a Federal Executive of the Australian Society of Exploration Geophysicists (ASEG) for more than 20 years including as president in 2013–14. Through his involvement in ASEG and its international associates, he was awarded a Service Certificate from ASEG and Recognition of Merit from the Society of Exploration Geophysicists of Japan. Koya also was awarded an Honorary Membership of ASEG in 2010, an Honorary Membership of the Association of Geoscientists and Environmentalists of Serbia in 2015, and the Harold Mooney Award from the SEG Near Surface Technical Section in 2015.
Suto translated The Microtremor Survey Method by Prof Okada, published in 2003 by SEG, and Application Manual of Geophysical Methods to Engineering and Environmental Problems published in 2014 by EAGE.
Koya has served on the SEG Global Affairs Committee since 2005, and was chairman in 2014.
