History of Disasters with highest death tolls

The 115 Antioch earthquake occurred on 13 December 115 AD. It had an estimated magnitude of 7.5 on the surface wave magnitude scale and an estimated maximum intensity of XI (Extreme) on the Mercalli intensity scale. The origin of the reported death toll of 260,000 is uncertain, as it only appears in catalogues of about the last hundred years.

The Antonine Plague of 165 to 180 AD, also known as the Plague of Galen (from the name of the Greek physician living in the Roman Empire who described it), was an ancient pandemic brought back to the Roman Empire by troops returning from campaigns in the Near East. The disease broke out again nine years later, according to the Roman historian Dio Cassius (155–235), causing up to 2,000 deaths a day in Rome, one quarter of those who were affected, giving the disease a mortality rate of about 25%. The total deaths have been estimated at five million, and the disease killed as much as one-third of the population in some areas and devastated the Roman army.

The Plague of Justinian (541–542 AD) was a pandemic that afflicted the Byzantine (Eastern Roman) Empire and especially its capital, Constantinople, as well as the Sasanian Empire, and port cities around the entire Mediterranean Sea, as merchant ships harbored rats that carried fleas infected with plague. Some historians believe the plague of Justinian was one of the deadliest pandemics in history, resulting in the deaths of an estimated 25–50 million people during two centuries of recurrence, a death toll equivalent to 13–26% of the world's population at the time of the first outbreak.

However, the figure of 230,000 dead is based on a historical conflation of this earthquake with earthquakes in November 1137 on the Jazira plain and the large seismic event of 30 September 1139 in the Transcaucasian city of Ganja. The first mention of a 230,000 death toll was by Ibn Taghribirdi in the fifteenth century.

On 7 October 1737, a natural disaster struck the city of Calcutta (modern-day Kolkata) in India. For a long time this was believed in Europe to have been the result of an earthquake, but it is now believed to have been a tropical cyclone. Thomas Joshua Moore, the duties collector for the British East India Company in Calcutta, wrote in his official report that a storm and flood had destroyed nearly all the thatched buildings and killed 3,000 of the city's inhabitants.

It ranks among the three largest forest fires ever recorded in North America. About 160 people died in and around Newcastle, including prisoners in the Newcastle Jail. Elsewhere, the totals were likely higher, given the number of lumbermen in the forests at the time (about 3000). To escape the blaze many residents took refuge with livestock and wildlife in the Miramichi River.

The fire, which burned over a million acres (4,000 km²) in less than a day, was the consequence of drought, hurricane-force winds, heat, the after-effects of the Port Huron Fire of 1871, and the ecological damage wrought by the era's logging techniques.

The 1887 Yellow River flood was a devastating flood on the Yellow River (Huang He) in China. This river is prone to flooding due to the elevated nature of the river, running between dikes above the broad plains surrounding it.

1900 to eradication. Declared eradicated May 8, 1980. 300 million smallpox deaths between 1900 and eradication would mean that, out of 4,713,503,215 worldwide deaths between 1900 and 1995, 6.36% were from smallpox. Applied to the estimated total of ca. 95 billion deaths between 50000 BC and 1900, this would mean that over 6 billion deaths in this period were from smallpox.
