Tectonic Mass Tragedy
One of history’s deadliest tectonic events was the Ganja earthquake in 1139. The epicenter was in what is now Ganja, Azerbaijan. This quake claimed 230,000 lives, caused the collapse of the Kapaz Mountains, and created seven new lakes by damming rivers with landslides.
Seismic Devastation
In 1920, the Chinese city of Haiyuan was struck by a horrific earthquake, with aftershocks felt for three years. Landslides buried homes, and some rivers even reversed their flow. Around 280,000 people lost their lives.
The First Super Cyclone
The first recorded super cyclone hit Calcutta in 1737. Winds reached 130 km/h (80 mph), whipping up the sea and unleashing massive waves that destroyed everything in their path. The death toll was around 300,000. The city was hit again by a severe cyclone in 1864.
Death at the Harbor
India’s Coringa port city was devastated by the second deadliest cyclone in history in 1839. Ships were destroyed, homes swept away by floods, and nearly 300,000 people died. The port city was never rebuilt.
The Fate of Byzantium
Antioch was a key city in the Byzantine Empire. In 526, a devastating earthquake struck, followed by days of raging fires. The disaster claimed over 300,000 lives.
Haiti’s Dark Day
Many still remember the 2010 Haiti earthquake. It collapsed 30,000 buildings and tragically took 316,000 lives.
Hellish Storm
On November 13, 1970, the Bhola cyclone hit East Pakistan (now Bangladesh) with winds of 185 km/h (115 mph) and massive waves that swept through the low-lying Ganges Delta. The death toll reached half a million.
When the Earth Moves
In the early morning of July 28, 1976, Tangshan, China, was struck by one of the deadliest earthquakes ever recorded. The magnitude 7.6 quake flattened 85% of the city’s buildings within minutes. A total of 300,000 people died during the main quake and aftershocks. The epicenter remains active, with additional quakes averaging magnitude 4.6 recorded in 2012, 2016, 2019, and 2020.
The Angry River
The second deadliest natural disaster happened in China when the Yellow River (Huang Ho) burst its banks in 1887. The floodwaters killed many, and the resulting epidemics claimed just as many lives. Estimates vary widely, from 900,000 to as many as 2 million deaths.
Water Rules After All
Surprisingly, the deadliest natural disaster was also a flood in China. In 1931, after three years of drought, the Yangtze River (Blue River) overflowed, flooding an area twice the size of Hungary. Death estimates vary, but at least one million people died, with more realistic figures around 4 million. It’s striking that the two deadliest natural disasters were both Chinese floods, yet they remain largely unknown.
