The photoelectric astrolabe at Yunnan Observatory （YO） observed apparent synchronous anomalous ATLR before the Wenchuan M8.0 earthquake （EQ） in May 12, 2008 and the Lushan M7.0 EQ n April 20, 2013. We compared the ATLR from the YO photoelectric astrolabe and EQ data since 1976. Anomalous ATLR was observed before several strong EQs in the Yunnan Province. We believe the photoelectric astrolabe can be used to predict strong EQs and the anomalous ATLR are a potential EQ precursor.展开更多
