Abstract:We calculate the abnormal changes of water temperature observation data, which contain 56 earthquakes more than MS5.0 all over the country. Then, we analyze the characteristics of intensity distribution, which can be used as one of the important references for selecting the resolution of water temperature instruments. Based on this, we carry out comparative observation experiments indifferent depths of a single well using the same type of instrument and analyzethe quantification basis of instrument resolution selectionunder different noise levels and disturbances. Meanwhile, we quantitatively analyze the selectiondetails of thesensor resolution of water temperature observation network in Yunnanand water temperature observation array in Longling. The results show that water temperature observation network in Yunnancan effectively monitor the abnormal change signals before earthquakes. However, the matching degree between the sensor resolutions and the environmental conditions of water temperature observation array in Longling should be further adjusted.
