Samples from the drilling and the dome of Unzen will be deformed with a unique high temperature high pressure press to monitor, in situ, the rheology and seismogenic character of the sample. The development of an ultra-high resolution neutron computed tomography system will provide insight into the process of magma fragmentation. It is hoped that a better understanding of magma failure will lead towards a first ever deterministic prediction model for Unzen type dome building volcanos with a view to disaster mitigation.

钻井和云顶的样品将在独特的高温高压下变形，以现场监测样品的流变性和发震特性。超高分辨率中子计算机层析成像系统的开发将提供对岩浆破碎过程的洞察。希望通过对岩浆破裂的更好理解，能够建立起第一个关于温岑型穹顶建造火山的确定性预测模型，以期减轻灾害。
