Study on the Physical Process and Seismogenic Mechanism of the Yangbi MS 6.4 Earthquake in Dali, Yunnan Province.

The article discusses the physical process and seismogenic mechanism of the Yangbi Ms 6.4 earthquake that occurred in Dali, Yunnan Province in 2021. The earthquake did not occur on a pre-existing active fault but on a buried fault in the eastern boundary of Baoshan sub-block. The study uses various seismological methods to analyze the earthquake sequence, seismogenic environment, and focal parameter characteristics, providing insights into the earthquake's source characteristics and trigger mechanism.
