The Hainan Dao volcanic field consists of a group of 58 Pleistocene-Holocene tholeiitic cones that are part of the Qionglei volcano group, also known as the Leiqiong volcanic field. The field covers about 4100 sq km of the northern part of Hainan Island (also known as Qiong), across the Qiongzhou strait south of the Leizhou (Liuchow) Peninsula. The Hainan Dao volcano field is of Pleistocene-Holocene age, but historical eruptions were reported in the Lingao and Chengmai areas in the 19th and 20th centuries. Leihuling and Maanshan, two of the best preserved volcanic cones, are oriented along an E-W fracture and are part of a cluster of about 30 cones in the Shishan and Yongzing regions.

|The Hainan Dao volcanic field (center) stretches across the northern part of Hainan Island. It covers about 3600 sq km of the northern part of the island (also known as Qiong Island), across the Qiongzhou strait from the Leizhou Peninsula (top-center). The Hainan Dao volcano field is of Pleistocene-Holocene age, but historical eruptions were reported in the Lingao and Chengmai areas.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
