STATISTIC ANALYSIS OF UNDERGROUND WATER TEMPERATURE OBSERVATION AT LIAOCHENG HYDROCHEMISTRY STATION

The dynamic characteristics, relationship between and water temperature anomaly and co-seismic effect of underground water temperature observation data at Liaocheng hydrochemistry station are systemically analyzed.The results show that:(1)multi-year dynamic feature and annual dynamic feature of the data is gradual rising or gradual dropping while diurnal dynamic feature is random fluctuation;(2)two water temperature abrupt rising anomalies are related with seismic activity;(3)there are no co-seismic effects.
