The Hainan volcanic field (also known as Khaynanj or Hainan Dao) comprises vast geologically young lava flows and numerous cinder cones on the northern part of Hainan Island in SE China.
Small fissure eruptions were recorded in 1883 from the Lingao cone and in 1933 from the Nansheling ridge.

Background
The Hainan volcanic field contains Quaternary lava flows that extend over about 4100 km2 on northern Hainan Island (also known as Qiong). This field, along with the Leizhou Bandao volcanic field across the Qiongzhou strait to the north on the Leizhou (Liuchow) Peninsula, forms the larger Leiqiong volcanic field (also called the Qionglei volcano group).It contains a group of 58 Pleistocene-Holocene tholeiitic cones that are part of the Qionglei volcano group, also known as the Leiqiong volcanic field. Hainan volcanic 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. Hainan 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.
