Hainan Volcanic Field
The Hainan Volcanic Field is a 4,100 square kilometres (1,600 sq mi) 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.[1]

Morphology
The field is made up of 58 Pleistocene-Holocene tholeiitic cones. The two best preserved cones (Leihuling and Ma'anshan (马鞍山)) are on an East-West fracture line that contains 30 young cones in the Shishan (石山) and Yongzing regions. Historically, small fissure eruptions have been recorded from the Lingao and Chengmai areas.
Eruptions
Two eruptions have been reported in recent history.
1883 Eruption
A small fissure eruption took place from Lingao cone in the Lingao area sometime in 1883.
1933 Eruption
Another small fissure eruption took place from the Nansheling Ridge in the Chengmai area on June 26 (date accurate to within plus or minus 4 days), 1933. This eruption probably ended on July 8, 1933.
