Gas monitoring in Japan

At present we are installing an on-line gas monitoring system at an hydrothermal well in the city of Beppu (Oita Prefecture, Japan), along the Japan Median Tectonic Line. This project is performed within the frame of a scientific collaboration between the Institute of Geological Sciences of the University of Bern, the Swiss Federal Institute of Aquatic Science and Technology (Eawag) (Dr. Kipfer), the Atmosphere and Ocean Research Institute (AORI) of The University of Tokyo (Dr. Sano), and the Institute for Geothermal Sciences of Kyoto University (Dr. Shibata).

The monitoring aims to provide a comprehensive dataset to infer any possible relation between gas geochemistry and seismic activity in the surrounding region. The measurements will last until the end of May 2018.
