- Abstract:
-
In the long-term crustal deformation data and geothermal temperature data from 2007 to 2019 in the Eryuan seismic station,the segmentation characteristics are obvious.For finding the reasons which cause the segmentation,methods of multi-data comparing,daily record scanning,and field surveying are used to look for near field changes in surrounding environment.The result is given that some small changes in near field environment can lead to terrible changes of observation data in some aspects such as amplitude,frequency,composition,and stability.Then the long term data is inconsistency and instability.It is argued that the near-field environment should be kept to ensure the stability and consistency of observation data.Then the long-term data can be used in medium and short term earthquake prediction.
