Yup...
1976
Jul. 28, Tangshan China: Twenty sq mi of the city was devastated by an earthquake that measured 7.5 in magnitude. The New China News Agency released figures following the inaugural Congress of the Chinese Seismological Society in Nov. 1979 which claimed 242,000 dead and 164,000 injured. The USGS estimates the real death toll at 655,000. This is the 20th century’s worst earthquake.
That’s nothing. The Chinese earthquake in 1555 killed over 500,000 people. That’s the most deadliest natural disaster ever.
