Ly Son Group Volcano — Vietnam

The Lý Son (formerly known as Cù-Lao Ré) volcanic group consists of four subaerial and nine submarine cones about 150 km off the coast of central Vietnam. Three of the subaerial cones form Lý Son Island, and the fourth forms An Binh (or Dao Be) Island. The basaltic volcanic field is of Holocene age (Whitford-Stark 1987, pers. comm.).
