Today, 33 years ago, on December 7, 1992 (Lunar Calendar, November 14, 1992) thousands of people were killed in Bolivia's mountain slopes. Due to a daily storm, the mountain slopes occurred early in the morning on December 7, 1992, about 200 kilometers north of the Bolivian government headquarters of Labas, causing thousands of deaths. The mountain slopes and the Tiffany river coast have been Bolivia's production area, and after the closure of the state mining company in 1985, about two hundred miners were still camping there to mine for their livelihoods. When the slopes occurred, miners were asleep, they were buried in ten meters deep mud houses, and the houses were all buried underground.
