Tangshan Earthquake (1976)

The Tangshan Earthquake occurred on Wednesday, July 28, 1976. It is believed to be the largest earthquake of the 20th century by death toll.The epicenter of the earthquake was near Tangshan in China, an industrial city with approximately one million inhabitants. The earthquake hit in the early morning, at 03:42 local time, and lasted 14 to 16 seconds.
Chinese government official sources state a magnitude of 7.8. It was followed by a major 7.1 magnitude aftershock some 16 hours later, increasing the death toll to over 255,000.
The number of deaths initially reported by the Chinese government was 655,000, but this number has since been stated to be around 240,000 to 255,000.[ Another report indicates that the actual death toll was much higher, at approximately 650,000 and explains that the lower estimates are limited to Tangshan and exclude fatalities in the densely populated surrounding areas.
