Based on geoelectric field observations from five stations within a 300km radius of the epicenter of the 2013 Laizhou M4.6 earthquake,covering the period from 2013 to 2014,this study first evaluated the observational quality of each station. Data from four stations with relatively high data quality,namely Anqiu,Lingyang,Dashan,and Malingshan,were then selected to calculate the Load/Unload Response Ratio (LURR). The results show that: (1)The LURR method,when applied to geoelectric field data,exhibited clear retrospective applicability to the Laizhou M4.6 earthquake,with significant high-value LURR anomalies observed at all four stations before the event.(2)The onset time of geoelectric LURR anomalies showed a clear dependence on epicentral distance. Stations closer to the epicenter,including Anqiu and Lingyang,displayed earlier anomalies,whereas more distant stations,including Dashan and Malingshan,showed delayed anomaly onset.(3)The maximum amplitude of LURR anomaly variation decreased with increasing epicentral distance,indicating stronger anomaly responses at stations closer to the epicenter. (4)The spatiotemporal evolution of geoelectric LURR anomalies was generally consistent with variations in the dominant geoelectric azimuth,suggesting that both indicators may reflect the response of the seismogenic medium to tectonic stress accumulation and providing mutual support for their use in earthquake-situation assessment.
