Clumps of molten lava (spatter) hurled above the
rim of a spatter cone have already started to cool and develop a thin
black skin on their surface. Width of the image is about 3 m. Credit:

Close view of cooled, solidified spatter fragments
hurled from an active littoral cone on the south shoreline of Kilauea
Volcano. The impact of the molten spatter hitting the ground flattened
the fragments into roughly circular disks. Credit: T. N. Mattox /

Very fluid fragments of molten lava ejected
from a vent that flatten and congeal on the
ground. Typically, spatter will build walls of solidified lava around a
single vent to form a circular-shaped spatter
cone or along both sides of a fissure
to build a spatter rampart.
