摘要
用地震活动非均匀度GL值作参数,使用1980—2011年祁连山西端M≥3.0地震资料进行GL值的空间扫描。结果表明,祁连山地区74%的M≥5地震前1—2年,在未来震中周围均有GL值异常出现,用R值对其进行评分,可以通过检验。
Taking the GL value, non-uniform seismic activity as parameter, the spatial scan of GL value on the data of earthquakes with M≥3.0 in the western end of Qilian from 1980 to 2011 was carried out. The results showed that for more than 74% earthquake with M≥5 in Qilian Mountains, GL anomalies appear around the potential epicenter before 1--2 year. This result has passed the test of R value grading. Typical example image shows the main characteristics.
