The Shaanxi earthquake is estimated to have been a magnitude 8 earthquake. Although the actual earthquake lasted for only a few seconds, it killed up to 60 percent of the population in two provinces, changed the paths of rivers, created massive floods and set off fires that burned for several days.
The earthquake struck late at night on Jan. 23, and had several aftershocks that continued the following morning, according to History.com. While it is not the strongest earthquake ever recorded, it struck in a highly populated area made up predominately of poorly constructed homes and buildings. This resulted in the high number of casualties, as all the structures in many of the cities near the epicenter ? the Wei River Valley ? were destroyed. In some areas, a 60-foot deep crevice opened in the ground. Serious landslides were associated with the earthquake, and severe destruction spanned up to 300 miles from the epicenter.Learn More

The surface directly above where an earthquake starts is called the epicenter, according to the United States Geological Survey. The location of the earthquake's origin is the fault or fault plane, and that is the place where two pieces of Earth move past each other, causing the ground to shake.Full Answer >
Earthquakes are caused by sudden movement in opposing tectonic plates in the earth. As plates move against each other, sometimes the rocky edges catch against one another. The rest of the plate remains in motion, putting stress on the sticking point, and when it gives way, an earthquake occurs.Full Answer >
