On February 3, 1996, a strong M_s7.0 earthquake occurred in Lijiang County, Yunnan Province. The macro epicenter was located near Heishui Snow Mountain east of Heilongjiang, about 25km north of Lijiang County. This earthquake is the strongest earthquake in northwestern Yunnan since the Ninglang earthquake in 1976. Before the earthquake, the Seismological Bureau of Yunnan Province made a medium-term forecast of the earthquake. After the earthquake, focal mechanism solutions given by different agencies all showed that the earthquake was a normal-fault type earthquake event. The main shock rupture study found that Lijiang
