About Longgang Group
Longgang Group is a volcanic field rising to 1,000 meters (3,281 feet) in China's Eastern Asia Volcanic Regions. Its last known eruption was in 350 CE. The volcano has produced 1 recorded eruption.
Geography & Climate
Longgang Group is located in China, within the Central East Asia Volcanic Province of the broader Eastern Asia Volcanic Regions. Situated at 42.33° N, 126.50° E in the Northern Hemisphere, the volcano lies within a temperate climate zone. With a summit elevation of 1,000 meters above sea level, Longgang Group is a moderately sized peak that remains accessible to hikers and researchers for much of the year. The volcanic landform is characterized as a cluster, which describes the physical shape and structure of the volcanic edifice as observed from the surface.
Geological Context
Longgang Group is an intraplate volcano, meaning it formed away from any plate boundary. These volcanoes are often powered by hotspots — plumes of abnormally hot mantle material rising from deep within the Earth. Hotspot volcanoes like Longgang Group tend to produce effusive eruptions with lava flows that can be relatively predictable, giving nearby communities in China more time to prepare. However, they can also produce explosive phases, particularly when magma interacts with groundwater. The dominant rock type is basalt / picro-basalt, a dark, fine-grained volcanic rock that forms from rapidly cooling, low-viscosity lava. Basaltic eruptions tend to be less explosive and produce fluid lava flows that can travel long distances. While less immediately dangerous than explosive eruptions, basaltic lava flows can destroy structures and infrastructure in their path, and volcanic gases released during these eruptions can affect air quality over a wide area.
Eruption History Summary
Longgang Group has 1 recorded eruption in the geological database, spanning from 350 CE to 350 CE.
GVP Reference Summary
The Longgang volcanic field covers 1,700 km2 in the Jilin Province of NE China. Basaltic and trachybasaltic lava flows cover a large area containing more than 150 Quaternary cinder cones and eight tuff rings. There is only one known cinder cone of Holocene age, Jinlongdingzi (Gold Dragon Peak); the eruption formed the large scoria cone and deposited tephra over a broad area to the E which was radiocarbon dated at about 1,600-1,700 years ago.
