Scientists Obtain Detailed Maps of Earthquake-Triggering High-Pressure Subsurface Fluids

Researchers in Japan and Taiwan have captured three-dimensional images of an entire geothermal system deep in the Earth’s crust for the first time.

Using advanced seismic imaging techniques, they mapped the underground distribution of phenomena such as fracture zones and phase transitions associated with seismic activity.

This work could lead to improvements in earthquake early warning models and aid the development of next-generation geothermal power, according to study leader Takeshi Tsuji of the University of Tokyo.

“With a clear three-dimensional image of where supercritical fluids are located and how they move, we can identify promising drilling targets and design safer and more efficient development plans,”

Tsuji says, highlighting the enormous potential of geothermal power for clean, large-scale energy production.

Author's summary: Scientists create 3D maps of subsurface fluids to improve earthquake warnings and geothermal power.
