Laboratory experiments for fire fountains (3):
Description of an hawaiian eruption
After the first phase (3 years and a half), no fire fountain activity
In the first few months of the
eruption: cyclic behaviour between
fire fountains and a quieter
activity (effusive activity)
cyclic behaviour between steady
states
is generated in magma chamber

a fire
fountain,
increase
in

and
in low
