Exploration and monitoring for CO2 reduction and energy development

Characterizing and monitoring geological formation plays a central role in CO2 reduction (e.g., CO2 geological storage and geothermal power) and energy development. Our group has developed geophysical data analysis methods and exploration devices (tools). For example, the automation of geophysical data analysis has made it possible to image underground at the highest resolution and find unknown gas and hydrate reservoirs. Furthermore, we have developed a minimal source system, achieving continuous monitoring of the reservoirs. Currently, we aim to apply our continuous monitoring system to future CCS projects. We have also developed technologies to characterize complex CO2 behavior in digitalized rock and promote CO2 mineralization.

Exploration and monitoring earthquake faults and volcanoes

We have developed a monitoring system to identify spatiotemporal variation inside the crust (e.g., seismic faults and volcanoes), contributing to disaster mitigation. For example, our laboratory has developed a monitoring system that captures the dynamics of the deep crust by using seismometer data distributed across Japanese Island. Based on geophysical data, we also try to predict the stress state around the plate boundary fault in the Nankai Trough and the Japan Trench.

Exploration of the moon and planets

Recently, geophysical exploration technology has been essential in the space environment. Geophysical exploration has already been carried out on Mars and the Moon, planned in Titan. Our laboratory analyzes seismological data on Mars and the Moon, measures the physical properties of extraterrestrial samples (Hayabusa2), and develops geophysical devices for the Moon exploration.


Message
Geophysical exploration of the earth and planets is accelerating thanks to the recent technological breakthroughs. I hope we will develop advanced exploration devices and methods, applying them to various engineering fields to achieve high-impact science. You only live once, so why don’t you try something no one has ever done before?
