由活火山产生的次声电波为火山爆发动力学提供了宝贵的见解。由于次声压力场可能与火山口释放的气体流量直接相关，次声还可提高火山灾害监测和管道过程持续研究的效力。在这里，我们提出了新的结果，从埃里伯斯，富埃戈，和比利亚里卡火山突出使用次声约束定量喷发参数，如喷发持续时间，源机制，和爆炸性气体通量。
Infrasonic airwaves produced by active volcanoes provide valuable insight into the eruption dynamics. Because the infrasonic pressure field may be directly associated with the flux rate of gas released at a volcanic vent, infrasound also enhances the efficacy of volcanic hazard monitoring and continuous studies of conduit processes. Here we present new results from Erebus, Fuego, and Villarrica volcanoes highlighting uses of infrasound for constraining quantitative eruption parameters, such as eruption duration, source mechanism, and explosive gas flux.
