Abstract
Before the Baoshan MS5.2 earthquake in Yunnan on May 2,2023,there were medium-short impending anomalies in seismicity and underground fluids.In terms of seismicity,there is a long seismic quiescence interval between earthquakes with MS≥5 in Yunnan,and there are medium-short impending anomalies in low-frequency activities of earthquakes with MS≥5.0 in Yunnan.There are temporal and spatial cluster activities of ML4.0 earthquakes in western Yunnan,the seismic belts of earthquakes with ML≥3.0 in Yunnan,and short-impending anomalies of precursory swarms of Mangshi ML4.0 earthquake.Underground fluid observation shows that there are synchronous short-impending anomalies in Longling water temperature,Longling water radon,and Xiaguan water radon,medium-short anomalies in Longling flow,and short-impending anomalies in Eryuan water temperature.关键词
