1556 Shaanxi earthquake facts for kids

The 1556 Shaanxi earthquake was a terrible earthquake that happened on the morning of 23 January 1556. It struck the Shaanxi region of China during the Ming Dynasty. This event caused the deaths of about 830,000 people. This makes it the deadliest earthquake ever recorded in human history.

The earthquake affected a huge area, destroying places over 840-kilometre-wide (520 mi). More than 97 counties felt its power. These counties were spread across many provinces, including Shaanxi, Shanxi, Henan, Gansu, Hebei, Shandong, Hubei, Hunan, Jiangsu, and Anhui. In some areas, up to 60% of all the people living there died. Scientists estimate the earthquake had a magnitude of about 8.0.

At that time, many people in the affected region lived in homes carved into artificial caves. These caves were made from a soft material called loess. Loess is known to be very weak and can easily cause landslides. Experts believe this is why so many people died during the earthquake. The ground shaking caused these cave homes to collapse, trapping or burying the people inside.

What Caused the 1556 Shaanxi Earthquake?

Earthquakes happen when large pieces of the Earth's crust, called tectonic plates, move. The 1556 Shaanxi earthquake was caused by movement along a major fault line. This fault is part of the Weihe–Shanxi Rift System. This system is located along the southern and eastern edge of the Ordos Block. The Ordos Block is a large, stable piece of the Earth's crust. When stress builds up along the edges of these blocks, it can suddenly release, causing an earthquake.

Why Was This Earthquake So Deadly?

The main reason so many people died in the 1556 Shaanxi earthquake was the type of homes they lived in. Many people lived in homes dug into cliffs or hillsides. These homes were called "yaodongs." They were made from loess, a soft, sandy soil.

When the powerful earthquake hit, these loess caves and cliffs collapsed very easily. This trapped or buried thousands of people. The widespread destruction of these homes led to the incredibly high number of deaths.
