中文摘要
导出了日本浅间火山的地震速度及其时间变化,该地区地震数据丰富。我们在山顶以西5-10公里深处发现了一个明显的低速体。我们在这项研究中发现的低速体直径为5公里或更小,因此用传统的地震层析成像技术是不可能探测到的。
英文摘要
We derived the seismic velocity and its temporal changes of Asama Volcano, Japan, where rich seismic dataset exists. We found a prominent low velocity body at depths of 5-10 km to the west of the summit. The low velocity body we found in this study has its diameter of 5 km or less, so that it has been impossible to detect with conventional seismic tomography techniques.
