This is already an island building up around the vent as the volcanic tephra piles up.

While the tephra has gradually washed away over the years, the hard lava core has proved far more resilient.
3
They are constructed of loose piles of volcanic debris (tephra) and lava flows on relatively steep slopes.
4
It consisted of roughly two-thirds tephra (rock fragments thrown up during an eruption) and one-third rapidly cooling lava.
5
Vigorous eruptions of steam and tephra were accompanied by an enhancement of the normal fine-weather potential gradient, and lightning was often observed.
