摘要
１９９５年４月１５日营口高坎Ｍ＿Ｌ５．０地震，震中区烈度达Ⅵ度。总结发现，震前在一定的震兆异常背景上，出现一批短临前兆异常，如深井水位、水氡、水温、水汞、地倾斜、地电阻率、宏观等。分析认为，它可能是介质较薄弱的老震区对大区域应力场作用增强的反映，是我省震情发展中一次重要的地震事件。
Epicenter intensity of Gaokan earthquake with magnitude M_L5.0 in Yingkouarea on Apr.15,1995,is Ⅵ.It has been fourld that some short and impending term precursoranomalies appearred on certain seismic premonitory background,for example,water level indeep wells,hydroradon,water temperature,hydromercury,ground tilt,ground resistivity,macroscopic anomalies and so on. According to analysis,the shock maybe reflected increasein action of large regional stress field to apply to Haicheng aftershock area in which the medi-um strength is lower.It is an important event in developing of earthquake situation in Liaon-ing area.
