| Abstract: | Based on the analysis of the precursor observation data around the Pearl River Delta region,it is found that there is some anomalous precursor in the data of gravity,body strain and water level before the M3.5 earthquake in the marine area near the Dangan islands.By studying on the starting and ending time,the range of the anomaly and the distribution of the stations,the anomalous precursor characteristics of this earthquake are concluded and have some referenced significance to the short-impending prediction for the moderately strong earthquake. |
