| Research Abstract |
The main purpose of this research is to develop a new method for the middle-scale (～100m to ～1000m) long-term strain observation using quantum standard as a measurement reference. We carried out continuous observations with laser strainmeters installed at Kamioka mine and Inuyama vault observatory, and performed parallel observations at Kamioka mine with a two-wavelength interferometer, an elastic-wave stressmeter, and an absolute distance meter. As a result, we have concluded that the two-wavelength interferometer would be a candidate for the middle-scale strain observation method if its baseline is scaled up.
