月震重定位
发布时间：2018-08-24 21:18
【摘要】：由于前人的月震定位结果主要是基于20世纪70、80年代的月球速度模型,定位结果误差较大,无法为月震层析成像等研究提供精确的月震参数.随着对月球内部结构研究的不断深入,月球速度模型及分层结构的精细程度已经有了很大提高.通过对Apollo月震数据解码及分析,重新拾取了月震初至数据,在总结前人震源定位的基础上,利用月球新近速度模型,采用Geiger震源定位方法进行了月震震源定位,给出了较为全面的月震参数目录,并对月震和地震的分布及形成机制进行了对比,可为以后月震及月球内部结构的深入研究提供更多的依据.
[Abstract]:Because the predecessors'lunar earthquake location results are mainly based on the lunar velocity model in the 1970s and 1980s, the positioning errors are too large to provide accurate lunar earthquake parameters for the lunar seismic tomography and other research. With the deepening of the lunar internal structure research, the precision of lunar velocity model and stratified structure has been greatly improved. By decoding and analyzing Apollo lunar earthquake data, the first lunar earthquake arrival data are picked up again. On the basis of summing up predecessors'focal location, using the lunar recent velocity model, the Geiger focal location method is used to locate the lunar earthquake source. A more comprehensive catalogue of lunar earthquake parameters is given, and the distribution and formation mechanism of the lunar earthquake and earthquake are advanced. The comparison can provide more evidence for further study of the lunar structure and internal structure of the moon.
