USGS PHOTO GLOSSARY OF VOLCANIC TERMS
Spatter cones are low, steep-sided hills or mounds of welded lava fragments that form along a linear fissure or around a central vent. As lava fragments erupt into the air, they often do not have time to cool completely before hitting the ground. Consequently, the fragments "spatter" as they land and bond to the underlying lava fragments, which are still hot and sometimes oozing down the side of the cone.
