对132个历史潜水事件的报告信息的分析表明，其中大多数（1 - 15）没有随后的岩浆或蒸汽岩浆喷发。据报告，只有18起案件没有强迫失踪现象，而在审议的大多数案件（72起）中，强迫失踪现象得到承认。这些前兆已被分析为一种功能的潜水事件及其可能的触发机制。不幸的是，现有信息的质量很差。然而，数据表明，异常地震活动、地面变形、产出变化、火山口和温泉的化学和温度是潜在的中期前兆，而地震震颤是常见的短期前兆。
An analysis of the reported information on 132 historical phreatic events indicates that most of these ( 1 15) were not followed by a magmatic or phreatomagmatic eruption. Only in 18 cases precursory phenomena are reportedly lacking, whereas they are recognized for the majority (72) of the considered cases. These precursors have been analyzed as a function of the kind of phreatic event and of its possible triggering mechanism. Unfortunately, the quality of the available information is poor. However, data suggest that anomalous seismicity, ground deformation, changes in the output, chemistry and temperature of fumaroles and thermal springs are potential mid-term precursors, whereas seismic tremor is a common short-term precursor.
