Abstract： This research proposes an anomaly detection method in earthquake precursor gravity data based on the CNNLSTM-CBAMmodel.The anomalydetection inearthquake precursor gravitydata is crucial for improving the timelinessof earthquakepredictions.Itextracts spatial features ofthegravitydata using CNN，anduses theLSTMtocapture long-term dependencyrelationships inthe time series.The CBAMisintroduced toenhance the model's abilityto focusonimportant features，thereby improving anomaly detection performance.Experimental comparisons with the anomaly detection methods suchas AutoEncoder，CNN，LST，andCNN-LSTmethodsshowthattheproposedmodelinthispaperoutperformsotrsin metrics such as MAE，MSE，RMSE，and .This model effectively identifies potential and abnormal dataand providesa reliable foundation forearthquakeriskmanagementandearly waming.Thisresearchofersnewinsights into theanalysisofearthquake precursor data.
