基于KML的地震震源三维动态演示
|
摘要
KML是Google Earth用来表达地理标记的一种文件格式。本文利用KML语言的编写实现了汶川地震以来发生在龙门山断裂带上的地震三维动态演示,通过人机交互的方式对时间轴进行拖动可以直观地显示出地震的空间三维分布情况。为全方位地观察地震活动和研究地震迁移规律提供了有利条件。
KML(Keyhole Markup Language)is a file format used by Google Earth to express geotag.Google Earth is apowerful 3Dvirtual software and is widely used in the geosciences.In this study,writing in KML,we achieve a 3D dynamic demonstration of earthquakes occurring since the Wenchuan earthquake on the Longmenshan fault zone.Dragging on the time axis not only shows the three-dimensional spatial distribution of earthquakes,but also provides useful information on the full range of the observed seismic activity and seismic migration.
