When was the 5 12 earthquake? When is the lunar calendar?

5. 12 Wenchuan earthquake in Sichuan was on May 12, 2008, 14: 28: 04 (Monday, the eighth day of April in the Year of the Rat).

5. 12 Wenchuan earthquake is located in shallow earthquakes, with focal depth of 10 ~ 20km, which is very destructive. Earthquakes can be divided into shallow earthquakes according to focal depth. Earthquakes that occur within 60 kilometers are called shallow earthquakes, and shallow earthquakes is mostly distributed in the outer edge of island arc, the inner side of deep trench and the coastal part of continental arc mountain, and mostly occurs at a depth of more than 30 kilometers below the surface.

However, the deepest earthquake can reach about 650 kilometers, which forms an inclined seismic zone-called benioff zones. Plate tectonics, a global tectonic theory called "Earth Science Revolution", links shallow earthquakes with deep earthquakes.
