Natural disasters have been an unavoidable part of human existence since the beginning of time. These powerful events are capable of decimating large populations of both humans and animals wherever they occur. In fact, some believe that it could be a natural disaster that ultimately triggers the end of the world, whenever that may come. While the impact of these disasters could be lessened by relocating people away from vulnerable areas, history shows that people have always been drawn to these risky zones, much as they are today.
8. Damghan Earthquake, Iran, 856 AD

The Damghan Earthquake, a catastrophic seismic event with a magnitude of 7.9, struck a 200-mile (320 km) stretch of Iran on December 22, 856 A.D. The earthquake's epicenter was located directly beneath the city of Damghan, the capital of Iran at the time. It resulted in around 200,000 fatalities, making it the fifth deadliest earthquake in recorded history. The disaster was triggered by the Alpide earthquake belt, a geological zone responsible for the formation of the Alpide mountain range, which is known to be one of the most seismically active areas in the world.

7. Antioch Earthquake, Antioch, 526 AD

In late May of 526 AD, a powerful earthquake struck the regions of Syria and Antioch, both part of the Byzantine Empire at the time. The calamity claimed an estimated 250,000 lives, making it one of the most devastating disasters in history. The earthquake also caused the port of Seleucia Pieria to rise by nearly one meter, which led to the silting of the harbor and its eventual inaccessibility. The tremor is believed to have measured over 7 on the Richter scale (VIII on the Mercalli scale). Following the quake, a massive fire broke out, destroying nearly all buildings that had survived the initial shock.
6. The Antonine Plague, Roman Empire, 165 AD-180 AD

The Antonine Plague is named after Emperor Marcus Aurelius Antoninus, who may have been one of its victims. This plague is also known as the Plague of Galen, after the Greek physician who chronicled the event. Based on Galen's accounts, historians suspect that the Antonine Plague was caused by smallpox or measles. It qualifies as a natural disaster due to its origin in a naturally occurring disease that caused significant loss of life.
It is believed that the Antonine Plague was brought to the Roman Empire by soldiers returning from battles in the east. Over time, the disease spread throughout the empire and to some northern tribes. The plague is estimated to have killed around 5 million people. During a second wave of the outbreak, Roman historian Dio Cassius recorded that 2,000 people were dying daily in Rome, which represented about one-quarter of those infected.
5. Crete Earthquake and Alexandria Tsunami, Greece and Africa, July 21, 365 AD

On July 21, 365 AD, a powerful earthquake struck beneath the Mediterranean Sea, likely with its epicenter near the Greek island of Crete. The quake, believed to have been of magnitude 8 or higher, destroyed nearly all towns on the island and caused extensive damage in Greece, Libya, Cyprus, and Sicily as well.
Following the earthquake, a powerful tsunami wreaked havoc in Alexandria, Egypt, as well as other nearby regions. The most detailed records of this event come from Alexandria. Ancient texts tell of ships being carried as far as two miles inland by the giant wave. Ammianus Marcellinus provides a vivid description of the aftermath, detailing how the earth trembled, the ocean receded, and then a massive wave inundated the city with seawater. It is estimated that thousands of lives were lost in this catastrophic event.
4. Eruption of Mount Vesuvius, Bay of Naples, Italy, August 24, 79 AD

The eruption of Mount Vesuvius in 79 AD and the subsequent destruction of Pompeii and Herculaneum serve as a stark reminder of the immense power of this active volcano. Vesuvius is considered one of the most dangerous volcanoes on Earth, with more people living in its vicinity than around any other active volcano. Moreover, it is inevitable that Vesuvius will erupt again.
When Mount Vesuvius erupted in 79 AD, it gave a warning in the form of an earthquake, which was unfortunately ignored. The quake was followed by the expulsion of volcanic debris and the appearance of a foreboding cloud over the mountain. Pompeii, just 5 miles away, and Herculaneum, even closer, were both struck. The inhabitants of these towns met their fates as expected from a volcanic disaster: suffocation, burning, and being covered by volcanic debris and runoff. What makes this ancient disaster particularly fascinating is the preserved evidence that we have today.
For over 1500 years, the ancient city of Pompeii remained buried in Italy. It was rediscovered during cleanup efforts following a major eruption in 1631 AD, though it wasn't fully uncovered until the 20th century. What followed was a shocking revelation of the tragic fate of its inhabitants. The agony of their deaths was preserved in plaster. As the bodies decayed long ago while encased in volcanic rock, cavities were formed, similar to those found in fossils. These voids were filled with plaster, resulting in lifelike statues of the people as they perished. Thousands of victims were entombed, and today, their number could be in the millions.
3. Plague of Justinian, Eastern Roman Empire, 541 AD

The Plague of Justinian was a devastating pandemic that struck the Eastern Roman Empire, particularly its capital Constantinople, in 541–542 AD. Historians commonly attribute the outbreak to the bubonic plague, which would later become infamous for its role in the Black Death of the 14th century. The social and cultural upheaval caused by this plague was comparable to that of the Black Death. The disease spread widely, affecting regions from central and southern Asia to North Africa, Arabia, and Europe, reaching as far north as Denmark and as far west as Ireland. For nearly two centuries, the plague would reoccur, reshaping the Mediterranean basin. This plague, named after the Byzantine Emperor Justinian I, who contracted it but survived, resulted in a staggering death toll of 40 to 100 million people.
2. Helike Tsunami and Earthquake, Helike, Greece, 373 BC

In 373 BC, the city of Helike was engulfed by the Gulf of Corinth due to an earthquake followed by a tsunami. The city remains submerged to this day. Ancient writers noted the devastation, with some mentioning that the ruins could still be seen beneath the water for centuries after the catastrophe. While it is believed that many people perished in the disaster, the exact number of casualties remains unknown.
The search for the lost city of Helike only began toward the end of the last century. Since then, numerous relics from Helike, as well as other towns, have been discovered. These include walls, pathways, coins, and more, all of which have been photographed and documented. Some believe this site could be the fabled Atlantis, although the destruction of Helike occurred during the lifetime of Plato, who claimed it happened 9,000 years before his time. It's possible that the story of Helike could have inspired Plato’s fictional account of Atlantis.
Numerous other smaller natural disasters took place throughout ancient history. Just as people faced such catastrophes in the past, we continue to face them today. One must wonder how many ancient civilizations were obliterated by natural disasters, the stories of which we have yet to uncover.
1. Minoan Eruption, Islands of Santorini and Crete, Greece, 1645 BC

Around 1645 BC, the island of Santorini was struck by a massive volcanic eruption. This eruption caused significant destruction on both Santorini and the neighboring island of Crete, both of which were inhabited by the Minoans at the time. The town on Santorini was not rediscovered until much later, in modern times.
It is intriguing to consider that the eruption on Santorini might have been the inspiration behind Plato's story of Atlantis. However, this remains a matter of speculation. It is believed that the ancient people of these islands were able to detect signs of the impending eruption and acted upon them. No victims have been found from the eruption, and it appears that any movable, valuable possessions were taken away before the disaster. However, archaeologists have uncovered buildings and large items that were left behind.
