Development of new methods for monitoring crustal deformation based on quantum standard

本研究的主要目的是发展一种以量子标准为测量基准的中尺度(~100m~~1000m)长期应变观测的新方法。我们用安装在神冈煤矿和犬山拱顶观测站的激光应变仪进行了连续观测，并在神冈煤矿用双波长干涉仪、弹性波应力计和绝对距离计进行了平行观测。因此，我们得出结论，如果双波长干涉仪的基线放大，它将成为中尺度应变观测方法的候选。

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.
