Dr. Koichi Hayashi

Geometrics is proud to congratulate Dr. Koichi Hayashi on his being selected to be the 2014 SEG Near Surface Honorary Lecturer. The lecture is titled "Integrated Geophysical Methods Applied to Geotechnical and Geohazard Engineering: From Qualitative to Quantitative Analysis and Interpretation"* He will be giving his lecture at 20+ different locations starting next summer. A listing of the locations and dates will be provided on the Geometrics website as well as the SEG website when they are available.

The talk will draw upon Dr. Hayashi's extensive experience in conducting and interpreting near surface studies as well his work in theoretical development of processing and interpretation of geophysical data, especially in the areas of Spatial Autocorrelation (SPAC) analysis of surface wave data. Electronic copies of some of Dr. Hayashi's papers can be found on the support section of our website.

Koichi is the main developer of the Seisimager program and has incorporated many of his theoretical developments into the software, so that Seisimager is the premier surface wave and refraction processing package available today. Dr. Hayashi came from Oyo Corporation to join us full time in San Jose, CA several years ago.

He has worked over the past 20 years as a Research Geophysicist focusing on providing better tools and algorithms for near surface geophysical methods after a college career that included a B.S. in Earth Sciences from Chiba University, an M.S. in Earth Sciences from MIT and a Ph.D. in Earth Resources Engineering from Kyoto University.


This lecture focuses on the application of geophysical methods to various problems associated with disaster mitigation and public safety. Topics include various geo-hazards, such as earthquake disaster mitigation and recovery, landslides and floods triggered by tremendous rain, asset management of civil engineering structures and effects of global warming. Among the geophysical techniques, the surface wave methods, resistivity methods and GPR are introduced. Together with the geophysical techniques, several related issues, such as performance-based design, standardization or regularization, internet and database are also discussed. This presentation includes many case studies from many countries of the world.
