Lava bubble burst sends spatter onto the flanks of a small
littoral cone (right center) on the Kamoamoa delta, south
coast of Kilauea Volcano. Though most littoral cones built
by bubble burst explosions are relatively low like this one,
we observed one cone as tall 8 meters with a diameter of
28 m its base. When we visited this same cone many weeks
later when the the delta had become inactive, the conduit
within the cone was more than 10 m deep, and the underlying
empty lava tube was well below sea level.
