“明灯1号”人工爆破地震地磁效应场地试验

Seismo-magnetic effects experimentation of the "Bright Lamp No.1" artificial explosion

中国地震局地球物理研究所于2007年12月12日在河北省怀来县实施了"明灯1号"大当量人工爆破,目的是以人工震源开展地球深部结构探测及地球物理学相关研究。这无疑是开展地震地磁效应场地试验的机会。在人工震源周围数十千米范围内开展了地磁三分量重复测量和地磁总强度连续测量。初步分析结果显示了有意义的信息。测量过程和数据处理结果也验证了流动地震地磁观测具有可靠的精度。

IGPCEA experimentized a large-equivalence artificial seismic explosion in Huailai county, Hebei Province on December 12th, 2007, which is named ＂Bright Lamp No. 1＂. The pur- pose of the experiment is to explore the earthrs deep structures and carry out other relative geophysical research with artificial explosion. Itrs a rare opportunity for field trial of the seismo-magnetic effects. Around ten kilometers range of the artificial explosion, we carried out geomagnetic three components repeat survey and geomagnetic total intensity continually survey. The primary analyzed result shows significant information. The survey process and data processing result in this exploration are both prove that mobile seismo-magnetic survey has credible precision.
