中文摘要
在地震资料丰富的日本浅间火山,我们得到了地震速度及其时间变化。我们发现了一个突出的低速体深度为5-10公里的高峰以西。我们在这项研究中发现的低速体的直径为5公里或更小,所以它已经不可能用常规的地震层析成像技术检测。
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.
