高分辨遥感在杭州活断层探测中的应用

Application of high resolution remote sensing technique to exploration of active fault of Hangzhou and its surroundings

详细探查城市及其周边地区的活断层,对于城市的防震减灾工作具有十分重要的意义。卫星遥感技术可在活断层探测中发挥重要作用。以杭州地区为例,系统介绍了提取第四纪松散沉积物覆盖区域的隐伏活断层信息流程和方法。结果证明,在弱活动构造地区,利用卫星遥感技术进行活断层探测是可行的。

It is important to explore the active faults in urban area and its surroundings for the earthquake disaster mitigation. Satellite remote seining technique can play an important role in active fault exploration. In this paper we take Hangzhou as an example, introduce the treatment of extracting buried active fault information covered by Quaternary unconsolidated sediments. The result shows that it is feasible to explore the active faults in weak active structural area by using satellite remote sensing technique.
