[[Lava]] entering the [[sea]] often builds a wide fan-shaped area of new land called a '''lava delta'''. Such new land is usually built on sloping layers of loose [[lava]] fragments and flows. On steep submarine slopes, these layers of debris are unstable and often lead to the sudden collapse of '''lava deltas''' into the sea.<ref>http://volcanoes.usgs.gov/Products/Pglossary/LavaDelta.html</ref>
