After centuries of prosperity, Coringa’s fortunes took a hit in 1789. In December of that, a storm that came to be called The Great Coringa Cyclone developed in the Bay of Bengal – fairly late in the cyclone season. It produced severe storm-tide conditions, and witnesses described a succession of three giant waves striking Coringa. The first storm tide drove ashore all the ships in anchorage. The second and third waves, even bigger than the first, flowed inland to inundate with salt water the fertile fields of the Godavari River’s delta. Coringa was almost completely destroyed, and around 20,000 people were killed.
Naming the 1789 disaster “The Great Coringa Cyclone” was akin to those who named the 1914 – 1918 global war “The Great War”, little knowing that an even greater calamity would soon follow. Those who named the 1789 storm did not suspect that an even bigger and far more devastating cyclone would strike Coringa within a lifetime.
By 1839, half a century after “The Great Coringa Cyclone”, the city had recovered from the 1789 disaster, rebuilt, and was more prosperous, populous, and bustling than ever. Then, on November 25th, 1839, again unusually late in the Bay of Bengal’s cyclone season, a monstrous cyclone struck Coringa, and brought with it a 40 foot storm surge. The extensive damage of the earlier 1789 cyclone paled in comparison to this one, which wholly destroyed the city of Coringa, wrecked all ships in the harbor and carried their wreckage miles inland, and killed over 300,000 people.
This time the damage was so extensive that the few survivors made no effort to rebuild. Most upped stakes and scattered to pursue their lives elsewhere, putting distance between themselves and what was thought to be a cursed city. The few who remained, some of whom were old enough to have experienced both devastating cyclones during their lifetimes, abandoned the coast altogether and rebuilt their community miles inland.
The 1783 Laki Eruption was not exactly one of history’s most powerful volcanic events. It was not a massive and violent eruption like Vesuvius or Krakatoa or Tambora. It did not look anything like what most people imagine when picturing a volcano going off with a bang, blowing its top, and releasing a massive amount of energy in a dramatic explosion. There were no fires reaching to the heavens, or rivers of lava rushing down the volcano’s sides.
Indeed, the Laki Eruption was not even a single explosive event. Instead, it was eight months of rumblings, interspersed by relatively small eruptions from time to time, with lava slowly seeping out of the side every now and then, while the volcano steadily spewed sulfuric dioxide gasses. Laki was not a vigorous and energetic volcano, but a tired and lazy one, steadily farting gasses for months before it finally subsided and went quiet. Nonetheless, Laki was the deadliest volcanic eruption in human history.
The Laki Eruption’s deadliness was a result of its steady gas releases during its eight months of rumbling and periodic small explosions. Massive amounts of gasses, including flourine and over 120 million tons of sundry sulfuric dioxides, were released into the air. They produced fog and haze as far away as Syria. The flourine settled on Iceland’s grass, which gave grazing animals flouride poisoning and killed most of the island’s livestock. The loss of livestock in turn caused a quarter of Iceland’s human population to starve to death.
But Iceland was and remains sparsely populated, so the death of a quarter of its population did not make Laki history’s deadliest eruption. The impact was beyond Iceland, where the eruption led to a decline in temperatures in the northern hemisphere. Winter temperatures in the US, for example, dropped 10 degrees Fahrenheit in 1783, and remained below normal for several years afterwards. Laki’s deadliest impact was not in the US or North America, either, however.
The Laki Eruption’s deadliest impact was in Europe and the northern hemisphere southeast of Iceland. The summer of 1783 had been a particularly hot one, and a rare high pressure zone formed over Iceland that year, which caused winds to blow to the southeast. Thus, when Laki began spewing prodigious amounts of sulfuric dioxide into the sky, they were carried by the winds from Iceland in a southeasterly direction.
Wherever those winds arrived, they brought misery with them. Laki’s gasses caused crop failures in Europe, draught in North Africa and India, Japan’s worst famine, as well as a historic famine in Egypt, a sixth of whose population starved to death in 1784. It is estimated that the Laki Eruption and its aftermath caused the deaths of an estimated six million people, making it the deadliest volcanic eruption in human history. It also illustrated how low energy but large volume eruptions over an extended period can have a greater impact than massive explosive eruptions.
The city of Antioch in the Roman province of Syria, modern Antakya in Turkey, was rocked by an extremely intense earthquake on December 13th, 115 AD. The upheaval caused widespread devastation and high loss of life in the region, destroying not only Antioch, but also the nearby city of Apamea, and inflicting significant damage upon Beirut as well.
The tremors also triggered a tsunami that slammed into the eastern Mediterranean coast. It caused extensive damage as far south as the seaport of Caesarea in the Roman province of Palestine, whose harbor was wrecked by the wall of water. It is estimated that about 260,000 people lost their lives, with many more injured and/or made homeless. Emperor Trajan was in the city at the time, and he barely survived the disaster.
In 115 AD, Antioch was a flourishing and economically vibrant Greco-Roman city on the Orontes River. It was the Roman Empire’s third biggest metropolis after Rome and Alexandria. The city owed its success to its location at the closest terminus of the Persian Royal Road, which linked the Mediterranean with Mesopotamia and Persia.
That made Antioch a trading center and entrepot for goods between the Roman and Persian worlds. Unfortunately, Antioch’s location had the misfortune of being near the junction of three tectonic plates – the African, Anatolian, and Arabian – whose friction made the region particularly susceptible to large earthquakes.
5. Tossing People and Trees in the Air Like Water Drops Shaken Off a Wet Dog
As described by the Roman historian Cassius Dio, the Antioch Earthquake was preceded by a loud and bellowing roar. Then the ground started to violently vibrate and shake, tossing people and entire trees up into the air as if they were water drops shaken off a wet dog’s fur.
Entire buildings were lifted off the ground, then violently slammed back to earth. Many were killed or injured by falling debris, and many more by buildings collapsing atop and burying them. The aftershocks, which continued for days, killed and injured many of those who had survived the first day’s tremors.
When the earthquake struck Antioch, the Roman emperor Trajan and his chief deputy and successor, the future emperor Hadrian, were wintering in the city, overseeing preparations for a military campaign against Parthia. Because Antioch served as headquarters for the war against Parthia, the city and the surrounding region were even more crowded than usual. The presence of legions encamped nearby, as well as the camp followers and other civilians engaged in support activities for the Roman army, swelled Antioch’s population.
Trajan managed to escape via a window from the building in which he had been housed, and was fortunate to suffer only light injuries. As buildings and debris kept falling due to aftershocks, the emperor and his entourage relocated to the open hippodrome, or race track, where they erected tents and set up house. His deputy Hadrian also escaped with only slight injuries. Both oversaw the recovery and rebuilding process, which was begun by Trajan, and after his death in 117, was continued and completed by his successor, Hadrian.
Sometime between 1642 – 1540 BC, Santorini in today’s Greece experienced one of the most powerful volcanic eruptions in recorded history. It was about four times as powerful as the gigantic Krakatoa eruption of 1883. The explosion sundered the island of Thera, and wiped out the flourishing Minoan settlement of nearby Arkotiri and surrounding islands.
Known as the Minoan Eruption of Thera, the event gave rise to the legend of the vanished civilization of Atlantis, which was doomed by a natural catastrophe and swallowed by the sea. Beyond legend, however, the Minoan Eruption was one of history’s most impactful natural disasters, with consequences not only to its own era, but with knock on effects and a chain of causation leading directly to the world in which we live today.
In addition to the immediate devastation of Thera and surrounding islands, the Minoan Eruption produced powerful tsunamis. They struck and devastated Crete, contributing to the decline of its Minoan civilization, and paving the way for its extinction. The Minoans were the Mediterranean’s greatest naval power, as well as the dominant power of the Aegean, including what became Greece and the Greek world.
A trading power, the Minoans were oriented towards Egypt and the Eastern Mediterranean, and were strongly influenced by those civilizations. While the Minoans flourished, the Aegean world in their thrall was by necessity oriented in the same direction, and strongly influenced by the Egyptian and eastern civilizations as well.
The Minoan Eruption weakened Crete and its Minoan civilization sufficiently to create a power vacuum in the Aegean. It was filled by the emerging Mycenaeans in mainland Greece. They went on to conquer Crete and destroy the Minoans, and became the dominant power of the Aegean. However, unlike the Minoans, the Mycenaeans’ energies were focused not on trade with Egypt and the Levant, but on colonizing the Aegean, the western coast of Asia Minor, the Black Sea coast, and the western Mediterranean.
That change of orientation significantly reduced Egyptian and eastern influences upon the Greeks, and the trajectory of their civilization when it flourished centuries later, long after the Mycenaeans had themselves disappeared. The Greeks ended up with a civilization and culture distinct from Egypt and the eastern Mediterranean, rather than becoming an extension and outpost of those civilizations. That had knock on effects on western civilization, which is founded upon that of the ancient Greeks. An argument could be made that today’s western civilization and its impact on the modern world would not exist but for the Minoan Eruption of the second millennium BC.
