摘要
用地质学、地球物理学和地震学相结合的途径分析表明,长白山天池火山处于活动构造背景中,西太平洋板块自日本海沟向我国大陆的持续俯冲作用是长白山天池火山喷溢的主要诱发机制,天池火山的未来喷发可能受北西西向走滑机制的控制。
The tectonic setting of Tianchi Volcano is analyzed in our study with geological, geophysical and seismological methods. The study shows that Tianchi Volcano is located in an active setting. The subduction of the West Pacific Plate from Japan Trench to the northeast of China is the main inducement of the eruptions of Tianchi Volcano. And it may be the strike-slip faulting of NWW that controls the future eruption of Tianchi Volcano.
