摘要:
2023年5月2日云南保山MS5.2地震前,地震活动性和地下流体存在中短临异常。地震活动性方面存在云南MS≥5地震平静间隔时间长,且云南MS≥5地震低频活动中短期异常;小滇西ML4地震时空丛集活动、云南ML≥3地震成条带分布和芒市ML4前兆震群短临异常。地下流体龙陵水温、龙陵水氡和下关水氡存在同步性短临异常,龙陵流量存在中短期异常,洱源水温存在短临异常。
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.
