Report 093


The purpose of this seminar is to share the recent advanced imaging technology in geosciences between Prof. Brian Kennett who is the pioneer of seismic tomography and some researchers and students from the Environment and Resources System Engineering Laboratory, Kyoto University.


This seminar was designed to welcome Prof. Brian Kennett from Australian National University who has a willingness to make a stop in Katsura Campus of Kyoto University during his journey in Japan. Since his visit is on the last week of winter semester, only several students could attend this seminar. Prof. Brian Kennett is a famous seismologist, in which his text books are used by many earth scientists all over the world as references.
After his lecture was given for around 45 minutes with its title was "What do seismic tomography images mean", he listened the presentations of 5 (five) members of Environment and Resources System Engineering Laboratory for around two hours. Norimitsu Nakata presented about Acceleration of the simulation of elastic wave propagation using GPU, Dr. Mohammad Rachmat Sule presented about Characterization of thin ore-dyke by using travel time tomography and seismic waveform modeling methods, Shohei Minato presented Crosswell seismic survey without borehole sources using seismic interferometry by multidimensional deconvolution, and Tatsunori Ikeda presented Estimation of macroscopic vibration characteristics of composite ground using surface wave exploration based on homogenization method. Additionally, Shohei Minato & Dr. Mohammad Rachmat Sule also presented about Integrated seismic interferometry and 3D CRS-Stack, applications for answering geodynamic problems in, Japan and Indonesia – a future research proposal.
The valuable input and suggestion from Prof. Brian Kennett were much awaited and those were honour for the presenters from Kyoto University. The seminar was close by his closing remark, in which he mentioned that the presentations given by laboratory members were very interesting and showed high quality research achievements.
