| Abstract: | The effect of tidal,peak,step,instrument drift and trend from the continuous tidal gravity data was removed by using the automatic extraction algorithm based on EMD and earthquake triggering algorithm,and achieved successfully the automatic extraction of tidal and non-tidal gravitational information.The examples show that the algorithm greatly reduces the manual work and it may be used for batch processing and quickly extracting the information of non-tidal changes of a large number of stations. |
