Abstract

Near-daily sampling of volcanic ash during a three-month eruption reveals shifts in mantle-derived liquid magma (melt) composition, highlighting its potential as a monitoring and forecasting tool. These shifts align with the amplitude of volcanic tremor, a persistent seismic signal, suggesting a link between magma viscosity, shallow bubble escape dynamics, and tremor changes.

岩浆成分在火山喷发时引起震动

在为期三个月的火山喷发期间，对火山灰进行的近乎每日采样揭示了地幔衍生的液态岩浆（熔体）成分的变化，凸显了其作为监测和预报工具的潜力。这些变化与火山震颤（一种持续的地震信号）的振幅一致，表明岩浆粘度、浅层气泡逸出动力学和震颤变化之间存在联系。
