Volcanic eruptions and their repose, unrest, precursors, and timing

Source(s):  National Academies Press (NAP)

To improve eruption forecasting and warnings to save lives, this report identifies research priorities for better monitoring of volcanic eruptions and three grand challenges facing the volcano science community. Volcano monitoring is critical for forecasting eruptions and mitigating risks of their hazards. However, few volcanoes are adequately observed, and many are not monitored at all. Enhanced monitoring combined with advances in experimental and mathematical models of volcanic processes can improve the understanding and forecasting of eruptions.

The authors highlight the need for satellite measurements of ground deformation and gas emissions, drone observations, advanced seismic monitoring, and real-time high-speed acquisition of data during eruptions.  New approaches in analytical capabilities to decipher magma history, and conceptual and experimental models of magmatic and volcanic phenomena, will provide new insights into the processes that explain how magma is generated and erupts. The report outlines several key questions and the following three challenges: 

  • Forecasting the size, duration, and hazard of eruptions by integrating observations with models;
  • Quantifying the life cycles of volcanoes and overcoming our current biased understanding;
  • Building a coordinated volcano science community.
