The Tengchong volcanic district, located in southern China near the border with Burma (Myanmar), was active during five periods ranging from the early Pliocene to the Holocene. Three main stages prroduced Pliocene to mid-Pleistocene basaltic rocks, mid- to late-Pleistocene silicic pyroclastic rocks, and Holocene basaltic andesites. The youngest volcanism in the 600 sq km volcanic field occurred in two stages during the early and late Holocene. Volcanic cones at the northern end of the field are sparsely vegetated and have clearly visible lava flows. Three basaltic-andesite centers, Dayinshshan, Maanshan, and possibly Heikongshan, are of Holocene age. An unconfirmed explosive eruption took place in 1609, and there are unconfirmed reports of eruptions in the Qing Dynasty (1644-1911). The Tengchong district is the site of active geothermal fields, the largest and highest temperature of which is the Rehai geothermal field. More than 20 hydrothermal eruptions have occurred at the Rehai geothermal field since 1993.

This false-color satellite photo shows young cinder cones and associated lava flows of the Tengchong volcanic field in southern China, near the Myanmar (Burma) border. Volcanism in the 600 sq km volcanic field has continued from the early Pliocene into historical time. The youngest cones are in the northern part of the field, where an eruption took place in 1609 AD.

Two of the many cinder cones of the Tengchong volcanic district rise above cultivated lands in southern China near the border of Myanmar (Burma). The Tengchong volcanic field was active during five periods ranging from the early Pliocene to the Holocene. The youngest volcanism in the 600 sq km volcanic field occurred in two stages during the early and late Holocene. An explosive eruption took place at the northern cone of Dayingshan in 1609. The Tengchong district is the site of active geothermal fields.

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.
