获取准确的喷发记录并了解喷发周期背后的火山过程对于制定现实的灾害评估和火山应急计划非常重要。在这里，我们对全新世（0.5 km 3 ）喷发进行了详细研究，这些喷发似乎在统计上是可预测的，因为它们往往发生在休止期之前，并且喷发的是演化最强烈的岩浆。这里确定的岩浆火山系统的基本属性除了为更可靠的概率时变灾害预测提供基础之外，还为限制岩浆过程的时间尺度和性质提供了范例。
Acquiring accurate eruption records and understanding the volcanic processes behind eruption periodicity are important in the development of realistic hazard assessments and volcanic emergency planning. Here, we use a detailed study of the Holocene ( 0.5 km 3 ) eruptions appear to be statistically predictable because they tend to occur just prior to a period of repose, and they erupt the most strongly evolved magmas. The fundamental properties of magma-volcano systems identified here offer a paradigm for constraining the time scales and nature of magmatic processes, in addition to providing a foundation for more robust probabilistic time-varying hazard forecasts.
