Description:
The weakest explosive volcanic eruptions globally, Strombolian
explosions and Hawaiian fountaining, are also the most common. Yet,
despite over a hundred years of observations, no classifications have
offered a convincing, quantitative way of demarcating these two styles.
New observations show that the two styles are distinct in their eruptive
time scale, with the duration of Hawaiian fountaining exceeding
Strombolian explosions by similar to 300-10,000 s. This reflects the
underlying process of whether shallow-exsolved gas remains trapped in
the erupting magma or is decoupled from it. We propose here a
classification scheme based on the duration of events (brief explosions
versus prolonged fountains) with a cutoff at 300 s that separates
transient Strombolian explosions from sustained Hawaiian fountains.
