| 摘 要： | The strain accumulation state in crustal interior and its migration trend can be inverted from observational data of earth tide tilts.In China,large earthquakes frequently occur in the border area between Yunnan and Sichuan Provinces.Using the observational data for years from 7 stations in this area,γ(the amplitude factor of earth tide tilts)values that characterize the strain accumulation state in crustal interior have been inverted in this paper.It has been found out that,Ms>5 events in the area often occur when γreaches an anomaly value.Using the time-space collocational stereomodelling the migration trend of strain accumulation can be determined to make a prediction for the probable location of a forthcoming earthquake in the area.
