Hainan Volcanic Field
The Hainan Volcanic Field is a volcanic field covering the northern half of Hainan, People's Republic of China. Although mostly Pleistocene-Holocene in age, minor eruptions have been recorded in the 19th and 20th centuries.
The field is made up of 58 Pleistocene-Holocene tholeiitic cones. The two best preserved cones are on an East-West fracture line that contains 30 young cones in the Shishan and Yongzing regions. Historically, small fissure eruptions have been recorded from the Lingao and Chengmai areas.
Two eruptions have been reported in recent history. A small fissure eruption took place from Lingao cone in the Lingao area sometime in 1883. Another small fissure eruption took place from the Nansheling Ridge in the Chengmai area on June 26, 1933. This eruption probably ended on July 8, 1933.
