How and When Do Volcanic Eruptions Start and Stop, and What Controls the Tempo of Everything in Between? I

Session ID#: 8269

Session Description:
There is much information now accumulating about the timing of volcanic eruptions, from the millennia (or longer) for the accumulation of magma into its eruptible state through to real-time observations of contemporary eruptive activity. A key aim of volcanology is to forecast the course of future events and provide advice on the timing and processes at ongoing eruptions on timescales that are relevant to humanity and with a degree of confidence about the processes involved. We invite contributions that address all the facets of this topic. These might include (1) magmatic forensics of past eruption products that contribute to accurate assessment of timescales and processes in past events; (2) studies of modern eruptions and the controls on their durations, including prolonged, multi-episode events; and (3) how temporal information about magmatic and volcanic processes can be translated into sound and useful advice to civil authorities for managing ongoing and future events.
