Magmatic System and Seismicity of the Arxan Volcanic Group in Northeast China

The Arxan volcanic group is one of the largest active volcanic fields in China. Its last eruption occurred ∼2,000 years ago, but it still has a potential of eruption in the future. The spatial distribution and migration channel of its magmatic reservoirs are still unclear. Here we precisely locate m...

Description
Summary:The Arxan volcanic group is one of the largest active volcanic fields in China. Its last eruption occurred ∼2,000 years ago, but it still has a potential of eruption in the future. The spatial distribution and migration channel of its magmatic reservoirs are still unclear. Here we precisely locate microearthquakes and study the detailed 3‐D velocity structure of the volcanic area using a large number of high‐quality P and S wave arrival‐time data recorded at 227 portable seismometers. A swarm of microearthquakes (M
