Seongsan Ilchulbong is an outstanding example of dramatic scenery that resembles a coastal forest. Seongsan Ilchulbong Tuff Cone is an 180-meter-high tuff cone formed by hydrovolcanic eruptions upon a shallow seabed approximately 5,000 years ago.
Seongsan Ilchulbong is not only preserves its bowl-like crater but also provides excellent sea-cliff exposure of diverse internal structures. These features have great geologic value in that they provide a basis for interpreting the eruptive and depositional processes of hydro magmatic volcanoes worldwide in addition to the past volcanic activity of this tuff cone.
