平谷台地磁加卸载响应比与地震
The relationship between the load unload response ratio(LURR)of geomagnetic field at Pinggu Station and earthquakes
【摘要】 将磁暴过程作为地球磁场对太阳风的加卸载响应,分析了平谷台1995年1月至1998年4月期间磁暴场的暴时扰日变化Ds(Z)的响应比值P(Z)的变化。发现P(Z)高值与平谷台550km,左右范围内MS≥50的中强主震有较好的对应。
【Abstract】 Taking the magnetic storm process as the load unload response of geomagnetic field to the solar wind,the LURR (P(Z)) of the storm disturbed day variation D s(Z) in the magnetic storm field observed at Pinggu Station from Jan.1995 to Apr.1998 was analyzed.The result shows that the emergence of the high values of P(Z) have close relationship with that of moderately strong earthquakes with magnitude M S≥5 0 within 550 km of the station.
