Research Themes

My research aims to clarify changes in underground conditions associated with natural phenomena like earthquakes and volcanic activity, as well as resource development (mainly geothermal development, but also including CO2 underground storage and oil/gas development) through seismic monitoring at field sites. By understanding the underground conditions in detail, it will be possible to contribute to safe and efficient resource development, as well as to a better understanding of natural phenomena.

Research steps include:

Literature review and preliminary analysis of existing data to select the target field
Install seismometers at the target field
Analyze seismic data to infer characteristics of seismic events and the underground structure
Integrate the results with other data such as physical exploration and geological information to understand underground phenomena associated with resource development or natural events
(In particular, this will provide basic information for decision-making in safer and more efficient operations in resource development)
