1556年中国陕西地震

The Shaanxi earthquake of 1556 is the deadliest seismic disaster in recorded history, with an estimated 830,000 fatalities across north-central China. Rupturing fault systems within the faulted interior of the Eurasian plate, it reached magnitude 8.0 and produced shaking rated at Mercalli intensity XI. Neither the focal depth nor the precise hour was set down by the chroniclers who recorded the catastrophe, yet the death toll—unmatched before or since—fixed the event as the reference point against which later Chinese earthquakes have been measured. Its combination of great magnitude, an intraplate continental location, and an extraordinary human cost makes it the archetypal catastrophic earthquake of the historical catalog.
