Tremor equations for geyser eruptions

点击翻译按钮获取中文摘要

We examined the significance of proposed equation" tremor equation" using laboratory geyser experiments. The experiments shows that the pressure oscillation shifts from eruption stage, through active stage, to inactive stage, thereafter an eruption onsets. In the active stage, two types of oscillation can be recognized, that is, fluid system oscillation and cyclic formation of bubbles. It is found that the proposed equation can explain the fluid system oscillation. The equation accounts for the experimental facts ;(1) pressure oscillation shifts from active to inactive stages as boiling becomes active,(2) efficiency of fluid oscillation depends on rates of bubble growth.
