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[edit]

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[edit]

Two eruptions have been reported in recent history.

1883[edit]

A small fissure eruption took place from Lingao cone in the Lingao area sometime in 1883.^{[citation needed]}

1933[edit]

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.^{[citation needed]}
