印尼8.9级地震前同一纬度“段”上东西两侧震兆信息讨论

Discussion on the Seismic Precursor Information in East and West Side on the Same Latitude Segment Before Indonesia M8.9 Earthquake

根据观测,2004年12月26日印尼苏门答腊附近海域发生8.9级地震前同一纬度“段”上两侧MS≥6.0地震活动是具有时间和空间信息的,二者都可以作出回顾性时、空预测的结果。不仅如此,根据红山地震台的记录仍然可以得到“活动时段”预测的结果。最后强调了我们对大震预测的基本认识:大震前小震活动水平的涨落和分布情况是预测未来大震活动时间和空间的基础资料,而且都是这次大震前的“整体多维活动”。

According to observation, there was some spatial and temporal precursory information in the seismic activity of M≥6.0 earthquakes at the both sides of the same latitude segment before Indonesia M8.9 earthquake, which occurred in Sumatra offing on Dec. 26, 2004, and the information can be tested through retrospection. Nevertheless, according to the records that recorded by Hongshan Seismostation, we can also get the prediction result of ＂active time interval＂. It is concluded that the seismic activity before strong earthquake, which is a kind ＂integer multidimensional activity＂, is basal information for earthquake prediction.
